Question

What type of phosphorylation occurs in glycolysis?

Answer 1

Glycolysis:

1. It is an oxidative process that occurs during both aerobic and anaerobic cellular respiration.
2. In this process, one glucose molecule is converted into two molecules of pyruvic acid.
3. It produces two molecules of pyruvate, ATP, NADH and water.
4. This process takes place in the cytosol of the cell.
5. Substrate-level phosphorylation is the type of phosphorylation that occurs in glycolysis.

Substrate level phosphorylation:

1. It is a type of chemical reaction.
2. In this reaction, a phosphate-rich compound (usually ATP) transfers its phosphate group to a substrate.
3. Example- ATP becomes ADP after transferring one of its phosphate groups to the substrate.
4. Glycolysis involves two substrate-level phosphorylation: 1,3-biphosphoglyceric acid to 3-phosphoglyceric acid and phosphoenolpyruvate to pyruvate.
