Answer:
The correct answer will be-true
Step-by-step explanation:
Phosphorylation is a set of reaction which adds a phosphate group to allow the formation of ATP molecule. This reaction could be of two types: substrate level and oxidative phosphorylation.
In the substrate-level phosphorylation, which requires a substrate molecule to proceed the formation of ATP molecule takes place during many process one of which is the glycolysis.
During glycolysis, the ATP molecules are produced using the carbon intermediates formed during the process which in the presence of enzymes form ATP molecule and the phosphorylated intermediates instead of Pi. Two substrate-level phosphorylation takes place during the process of glycolysis.
Thus, true is the correct answer.
