in total, how many molecules of nadh and fadh2 are produced during the oxidative metabolism of one molecule of glucose?
Answer:
Ten molecules of NADH, and two molecules of FADH2
Explanation:
Most of the usable energy obtained from the breakdown of carbohydrates or fats is derived by oxidative phosphorylation, which takes place within mitochondria. For example, the breakdown of glucose by glycolysis and the citric acid cycle yields a total of four molecules of ATP, ten molecules of NADH, and two molecules of FADH2. Electrons from NADH and FADH2 are then transferred to molecular oxygen, coupled to the formation of an additional 32 to 34 ATP molecules by oxidative phosphorylation. Electron transport and oxidative phosphorylation are critical activities of protein complexes in the inner mitochondrial membrane, which ultimately serve as the major source of cellular energy.

Why do muscles work in pairs
Answer:they only pull in one direction
Explanation:
Answer
Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.

during action potential, positively charged ________ ions move inside the cell.
Sodium ions move inside the side during action potential.
This stage of action potential is called depolarization.This open voltage gated sodium channel.What is action potential?
- Action potentials (those electrical impulses that send signals around body) are nothing more than a temporary shift (from negative to positive) in the neuron's membrane potential caused by ions suddenly flowing in and out of the neuron.
- It consists of phases:
depolarization overshootrepolarization.- An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

Explain your stepwise procedure for building the protein from DNA sequence
Answer:
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

All producers and autotrophs go through photosynthesis?
False ?
True ?
Because autotrophs produce their own food, they are sometimes called producers. ... Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.
Tumours can be life-threatening if tumour cells are able to grow through tissues from their original site, or detach and spread to other organs as secondary tumours. Tumours that can spread like this are called malignant tumours. What are the factors contributing to the development of malignant tumours
Answer:
malignant cells eventually acquire the ability to metastasize.
Explanation:
Cancerous tumors are called malignant neoplasms. When cells grow and divide more than they should, they can form tumors. Malignant neoplasms can spread to nearby tissues as well as to parts of your body that are far away.
What is tumor?A mass of aberrant tissue that develops when cells expand and divide faster than they should or do not die when they should. There are two types of tumors: benign, which do not cause cancer, and malignant (cancer).
Benign tumors have the potential to become quite large, but they do not metastasize (spread to neighboring tissues or other regions of the body) or invade. Malignant tumors have the potential to metastasize, or spread to neighboring tissues and invade them. In addition, they have the ability to travel throughout the body via the circulatory and lymphatic systems. Also referred to as a neoplasm.
Cancerous bumps are big, hard, painless, and sudden. The bulk will develop steadily. Cancerous lumps can be felt on the breast, testicle, neck, arms, and legs.

Diabetes is a disease where the body is unable to produce enough insulin in the pancreas to help lower the levels of blood glucose.
Which two organelles are most responsible for producing insulin in the pancreas?
A)
nucleus and ribosome
B)
nucleus and mitochondria
C)
ribosome and mitochondria
D)
Golgi apparatus and lysosome
Answer:
A) Nucleus and Ribosome
Explanation:
Diabetes can be a very chronic disease if not properly controlled, it mostly affect the aged people. If not properly treated it can in some cases lead to the death of the individual.
Diabetes occurs when the pancreas in the body system does not produce any insulin, the insulin is a type of hormone that is found in the body, this hormone helps to normalize the amount of blood sugar that is present in the human body.
The two organelles in the pancreas that is responsible for the production of insulin in the body is; nucleus and ribosome
What type of tissue comprises wood in woody stems?
Answer: Woody plants have an extra layer of protection on top of the epidermis made of cork cells known as bark. The vascular tissue of the stem consists of the complex tissues xylem and phloem which carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.
Explanation:
Bark protects woody plants' epidermis with cork cells. Xylem makes up most of a stem's wood, while phloem is in the bark.
What makes up most of a woody stem?Many shrubs and plants have woody stems. The most notable distinction between the two kinds of stems is that woody stems are mostly made of firm cork rather than soft epidermis. As the cork ages, it develops bark and hard woods.
The inner and outer derivative products of the vascular cambium are secondary xylem (wood) and phloem. The primary constituents of xylem are dead cells with thicker cell walls rich in cellulose, hemicelluloses, and lignin. Xylem serves as the plant's mechanical support system and conductor of water and minerals.
