Answer:

The answer is Fallicitated Diffusion. Also Osmosis, because it requires an input of energy and is accomplished through carrier proteins and channels. I'm really sorry if I'm wrong. I might be wrong :( sorry in advance if i am.

Answer:

True

Explanation:

plz give me brainiest

Answer:

True

Explanation: If you take a look at a periodic table you will see a decimal number for example 7 N (Nitrogen) 14.01, the 14.01 is the total AMU (atomic mass unit) of the element witch includes the valence electrons. Hence true would be the correct answer.

Answer: Without Golgi apparatus there would also be no way for the cell to produce various amounts of macro-molecules or transport enzymes out of the cell. I don't really know how else to answer it, sorry if this didn't help.

Answer:

yes!

Explanation:

hi, the atomic number of an element is usually right above the element symbol on the periodic table, and represents the amount of protons in the atom.

Answer:

D, core

Explanation:

Explanation:

How does energy control the loss of water to a hypertonic enviorment to avoid dehydration?

Answer:here the symbol M stands for the mass of the object, and V the volume. Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l). A block of wood has a mass of 8 g and occupies a volume of 10 cm3.

Answer:

[tex] H_2SO_4 [/tex]

Explanation:

In the first option, the compound [tex] HClO_3 [/tex] has 1 hydrogen atom and 3 Oxygen atoms. There are 3 times as many oxygen atoms as hydrogen atoms.

In the second option, the compound [tex] H_2SO_4 [/tex] has 2 hydrogen atom and 4 Oxygen atoms. That is 2:4 = 1:2. Therefore, there are twice as many oxygen atoms as hydrogen atoms.

In the third option, the compound [tex] H_2O [/tex] has 2 hydrogen atoms and 1 Oxygen atom. There are ½ times as many oxygen atoms as hydrogen atoms.

In the fourth option, the compound [tex] H_3PO_4 [/tex] has 3 hydrogen atoms and 4 Oxygen atoms. 4 oxygen atoms to 3 hydrogen atoms.

Answer:

Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.

Simplified diagram of pyruvate oxidation. Pyruvate—three carbons—is converted to acetyl CoA, a two-carbon molecule attached to coenzyme A. A molecule of coenzyme A is a necessary reactant for this reaction, which releases a molecule of carbon dioxide and reduces a NAD+ to NADH.

In eukaryotes, this step takes place in the matrix, the innermost compartment of mitochondria. In prokaryotes, it happens in the cytoplasm. Overall, pyruvate oxidation converts pyruvate—a three-carbon molecule—into acetyl two-carbon molecule attached to Coenzyme A—producing an t, N, A, D, H, end text and releasing one carbon dioxide molecule in the process. Acetyl  C, o, A, end text acts as fuel for the citric acid cycle in the next stage of cellular respiration.

Pyruvate oxidation steps

Pyruvate is produced by glycolysis in the cytoplasm, but pyruvate oxidation takes place in the mitochondrial matrix (in eukaryotes). So, before the chemical reactions can begin, pyruvate must enter the mitochondrion, crossing its inner membrane and arriving at the matrix.

In the matrix, pyruvate is modified in a series of steps:

More detailed diagram of the mechanism of pyruvate oxidation.

1. A carboxyl group is removed from pyruvate and released as carbon dioxide.

2. The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.

3. The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.

A carboxyl group is removed from pyruvate and released as carbon dioxide.

The two-carbon molecule from the first step is oxidized, and NAD+ accepts the electrons to form NADH.

The oxidized two-carbon molecule, an acetyl group, is attached to Coenzyme A to form acetyl CoA.

Step 1. A carboxyl group is snipped off of pyruvate and released as a molecule of carbon dioxide, leaving behind a two-carbon molecule.

Step 2. The two-carbon molecule from step 1 is oxidized, and the electrons lost in the oxidation are picked up 2 \text{NADH}NADHstart text, N, A, D, H, end text are generated from \text{NAD}^+NAD

Step 3. The oxidized two-carbon molecule—an acetyl group, highlighted in green—is attached to Coenzyme A (\text{CoA}CoAstart text, C, o, A, end text), an organic molecule derived from vitamin B5, to form acetyl \text{CoA}CoAstart text, C, o, A, end text. Acetyl \text{CoA}CoAstart text, C, o, A, end text is sometimes called a carrier molecule, and its job here is to carry the acetyl group to the citric acid cycle.

The steps above are carried out by a large enzyme complex called the pyruvate dehydrogenase complex, which consists of three interconnected enzymes and includes over 60 subunits. At a couple of stages, the reaction intermediates actually form covalent bonds to the enzyme complex—or, more specifically, to its cofactors. The pyruvate dehydrogenase complex is an important target for regulation, as it controls the amount of acetyl \text{CoA}CoAstart text, C, o, A, end text fed into the citric acid cycle^{1,2,3}

If we consider the two pyruvates that enter from glycolysis (for each glucose molecule), we can summarize pyruvate oxidation as follows:

Two molecules of pyruvate are converted into two molecules of acetyl \text{CoA}CoAstart text, C, o, A, end text.

Two carbons are released as carbon dioxide—out of the six originally present in glucose.

Why make acetyl \text{CoA}CoAstart text, C, o, A, end text? Acetyl \text{CoA}CoAstart text, C, o, A, end text serves as fuel for the citric acid cycle in the next stage of cellular respiration. The addition of \text{CoA}CoAstart text, C, o, A, end text helps activate the acetyl group, preparing it to undergo the necessary reactions to enter the citric acid cycle.
