Question

Which of the following steps is associated with ATP formation (substrate level phosphorylation)?

Answer 1

Explanation:

Succinyl CoA to Succinic acid is a step in Krebs cycle. A 1,3 bis PGA to 3 PGA is a step involved in glycolysis or Calvin cycle. Conversion of PEP to pyruvate is also a step involved in glycolysis. During all of these steps ADP is converted to ATP. Hence ATP formation is seen in all these steps.

Thus, the correct answer is 'All of these.'
