Question

The ATP produced during glycolysis are produced by
Options
A Substrate level phosphorylation
Correct Answer
B Oxidative phosphorylation
C Photophosphorylation
D Fermentation
Correct Answer

Option A is the correct answer.

Detailed Explanation

The ATP in glycolysis is generated directly when a high-energy phosphate group is transferred from an intermediate molecule (like 1,3-bisphosphoglycerate or phosphoenolpyruvate) to ADP. This is substrate-level phosphorylation.

Hint

Is the ATP made by a direct enzymatic transfer (substrate-level) or via a gradient (oxidative)?
