Question

How many ATP are produced in glycolysis and TCA Cycle?

Answer 1

TCA cycle:

1. The Tricarboxylic acid (TCA) cycle, commonly known as the Krebs or citric acid cycle, is the primary source of energy for cells and is an essential component of aerobic respiration.
2. The TCA cycle and glycolysis are both parts of the cellular respiration process.
3. In living organisms, cellular respiration occurs when food materials are broken down and the energy released is stored in the form of ATP, which is used to perform a variety of essential functions.
4. The primary respiratory substrate is carbohydrate.
5. Glycolysis occurs in the cytoplasm of all living creatures and is the first step in cellular respiration.
6. Because it does not require oxygen, it can also be found in anaerobic organisms.
7. It's a multi-step enzymatic reaction in which glucose is partially oxidized and two molecules of pyruvate are formed.
8. In glycolysis, there is a net gain of 2 ATPs.
9. 2 ATPs are produced in the TCA cycle per glucose molecule (2 acetyl CoA).
