g One can measure ATP production from isolated mitochondria in vitro (in a test tube). Changing the pH of the solution that the mitochondria are in results in a similar change the pH of the intemembrane space. If the pH of the solution that the isolated mitochondria are in is raised and everything else remains constant, what is the effect on ATP synthesis
Answer:
This will lead to an decreases in the ATPs synthesis. This is because low pH , high acidity favours ATP synthesis, because it increases the proton concentration for electrochemical gradients needed for energy that ATPase enzymes makes used of synthesis of ATPs.
Therefore a rise in the pH(low acidity) lowers protons levels, and therefore reduced electrochemical gradients , with a drop in energy for ATPs synthesis.

Which statement about enzymes is true?
An enzyme functions to increase the activation energy in a reacton.
Enzymes are proteins that function as catalysts in nonliving things.
Each enzyme can catalyze many different biochemical reactions.
Enzymes and substrates fit together like a lock and key.
Answer:
Enzymes and substrates fit together like a lock and key since, in one enzymatic reaction, only the correct substrate (i.e., the key) binds to its corresponding enzyme (i.e. the lock).
Explanation:
An enzyme (or catalyst) is one protein that has catalytic functions, being therefore capable of accelerating chemical reactions. The enzymes are known to control the rate of these chemical reactions (i.e., catalysis) without suffering alterations during these processes. Thus, the enzymes are proteins that catalyze chemical reactions that are not favored under normal conditions. Moreover, one enzyme may catalyze more than one chemical transformation, as well as the same reaction may be catalyzed by two or more enzymes.

Is it important before a blood transfusion to know blood types? Why? What are the benefits or consequences?
Answer:
It is extremely important to know all types of blood because if you donate the wrong type of blood to another person, he/she will get sick.
Explanation:
Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be extremely life-threatening.
The color of the mustard plant in Lab 4 (Natural Selection) was determined by a single gene with two alleles (Y or y). The Y allele was dominant to y allele, and Y gave us a green plant, and yy a yellow-green plant. You measure the following genotype frequencies: YY = 0.5; Yy = 0.25; yy = 0.25. You calculate the following Hardy-Weinberg Frequencies: YY = 0.30; Yy = 0.56; yy = 0.14 This population looks like it has evolved. We can tell this because : Group of answer choices
Answer and Explanation:
It occurs evolution whenever the allelic frequencies in the genic pool change. If the population is not in Hardy-Weinberg equilibrium, it is because one, some, or several of the model's assumptions are not met. If we want to know if a population is evolving, we must observe the frequencies of the population, and if they change over time. If there is a change, it might also be reflected in the phenotypic frequencies.
In the exposed example there was an evident change in the population genetic frequencies.
1) Genotype frequencies: YY = 0.5; Yy = 0.25; yy = 0.25
Genic or Alleleic frequency:
Frequency of y= f(q)= √0.25 =0.5Frequency of Y= f(p)= 1- 0.5 =0.52) Hardy-Weinberg Frequencies: YY = 0.30; Yy = 0.56; yy = 0.14
Genic or Alleleic frequency:
Frequency of y= f(p)= √0.14 =0.374
Frequency of Y= f(p)= 1- 0.5 =0.626
The allelic frequencies and hence the genotypic frequencies changes, so we can assume that there was evolution.
There are two different alleles for flower color, P and p. The image shows a purple sweet pea that is labeled with its two alleles for petal color. A purple sweet pea is labeled Upper P Upper P. Which is the genotype of the sweet pea?
Answer:
There is no diagram but the question can be answered using the description. The options to this question are:
Which is the genotype of the sweet pea?
A.heterozygous dominant
B.heterozygous recessive
C.homozygous dominant
D.homozygous recessive
The answer is C (homozygous dominant)
Explanation:
According to the question, a flower colour gene in a pea plant possesses two different alleles, P and p. Lettercase is used to illustrate that allele P (upper case) is dominant over allele p (lowercase) i.e P will be expressed over p in the flower colour gene.
According to the question, the pea plant exhibits a purple flower colour and is labelled as PP. This genotype is said to be homozygous because the same alleles (P) make up the plant's genotype. Since the allele P coding for purple coloration is dominant, the purple sweet pea is said to be HOMOZYGOUS dominant i.e. possess the same dominant alleles for that gene.

In perspective, with Earth being 4,500,000,000 years old and humans being around 1,400,000 years; how long out of a 24 day time period have we as humans been here.
Answer:
Day time period have we as humans been here: 26 seconds
Explanation:
4,500,000,000 years = 1 day
1,400,000 years = X
X = 0.0003111
1 day = 86,400 seconds
0.0003111 = X
X = 26 seconds
In term of the Earth in 24-hour clock, Homo sapiens appeared on our planet only in the last 26 seconds, it means that in geologic time, humans have existed for only a brief time period and thereby it is a relatively new species.
You are monitoring the metabolism of two different cultures of the same species of yeast, which you have labeled Culture A and Culture B. One of your observations is that Culture A is using up about 10 times the amount of glucose per unit of time as Culture B. Which one of the following conclusions could you reasonably draw regarding these cultures?
A. Culture A would be accumulating lactic acid.
B. Culture A is being grown aerobically; Culture B is being grown anaerobically.
C. Only Culture A is recycling its NADH back to NAD+.
D. Culture A and Culture B are synthesizing the same amount of ATP per unit of glucose in glycolysis.
E. None of the above conclusions could be drawn from the information given.
Answer: D
Explanation: The experiment was set up using the very same species of yeast labeled differently. What this means is that they are of the same type or kind and thus would exhibit similar features from feeding to the metabolism of the food they take and subsequent production of by-products of the fermentation process. In this regard, therefore, the reasonable conclusion that can be drawn regarding these cultures is that both cultures A and B are synthesizing the same amount of ATP per unit of glucose in glycolysis (the cellular degradation of the simple sugar glucose to yield pyruvic acid, and ATP as an energy source).

When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
In experiment #2 you are asked to use the scientific method to develop and execute a method of separating a mixture of sand, salt and iron pellets. Imagine you are in a lab and notice that a plate of bacteria grow faster in the presence of sunlight. After that single observation, you come to the conclusion that sunlight causes bacteria to grow fast. What would be the next step in the scientific method for this experiment?
Answer:
1. separation can be done with help of magnetic bar and filtration.
2. the next step will be testing the hypothesis.
Explanation:
1. Separation of iron pellets from sand, and salt first
Use a magnet
Due to magnetic force iron pallets will attach with it and separation will occur from sand and salt.
After separation of iron pallets, add water to mixture of sand and salt and heat until salt get dissolved then filter the salt water.
This will help in separating all three components of mixture to separate.
2. Bacteria growth
Hypothesis must be tested-
In this case a hypothesis and conclusion is represented. Conclusion is provided that in presence of sunlight growth of bacteria is faster. So the hypothesis must be verified by scientific experiment to be a valid theory by measuring or monitoring growth in presence of sunlight.
Suppose a certain drug is tested in the laboratory and is found to create holes in both mitochondrial membranes. Scientists suspect that the drug will be harmful to human cells because it will inhibit.
A. The formation of alcohol C. Glycolysis
B. Oxidative phosphorylation D. Kreb’s cycle
Answer:
The options to this question is incomplete, the correct options are:
A) the citric acid cycle.
B) oxidative phosphorylation.
C) glycolysis.
D) the citric acid cycle and oxidative phosphorylation
The answer is D
Explanation:
Cellular respiration is an important metabolic process carried out by the cells of living organisms including human cells. Aerobic cellular respiration involves three main stages viz: Glycolysis, Kreb's cycle, and Oxidative phosphorylation. These three processes occur to bring about the breakdown of glucose to synthesize ATP.
Glycolysis occurs in the cytoplasm while Kreb's cycle and Oxidative phosphorylation both occurs in the matrix and intracellular membrane of the Mitochondrion respectively. Hence, a drug that causes holes in both mitochondrial membranes will affect both Kreb's cycle and Oxidative phosphorylation.
The stimulus interval has a profound effect on the contraction force of the muscle. In your own words explain what happened when the muscle was stimulated in rapid succession. At which interval did the volunteer's muscle twitches begin to merge together (summate)
Answer:
The skeletal muscle is stimulated by means of action potentials that are caused by the neuromotor plate. These action potentials are one after the other and can become cumulative once the muscle fibers pass the refractory phase of the action potential.
The refractory stage is that stage in which action potentials are not admitted, therefore where the muscle fibers do not accept stimuli to contract.
Once this refractory stage is over, more action potentials can be admitted, which would be summative and the muscle fiber would contract with greater power.
Explanation:
If a muscle is repeatedly stimulated, the contraction will be weaker or the muscle will fatigue more easily, triggering muscle failure.
If the muscle is stimulated with a longer pause between contraction and contraction, the action will be performed with more power.

Assume that plant weight is determined by a pair of alleles at each of two independently assorting loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 4 g to weight and that each allele represented by a lowercase letter contributes 1 g to weight. If a plant with genotype AA BB is crossed with a plant with genotype aa bb, what weights are expected in the F_a progeny?
A. 1 g
B. 4 g
C. 8 g
D. 10 g
Answer: choice D. 10g
Explanation:
The cross is AABB x aabb so the F1 progeny would have AaBb genotype.
The question states that dominant alleles(uppercase letters) contribute 4g and recessive ones contribute 1g to the weight of the plant.
so for AaBb we would have 4+1+4+1=10g.
