The ATP Made During Glycolysis is Generated By

Question

The ATP made during glycolysis is generated by
A) substrate-level phosphorylation.
B) electron transport.
C) photophosphorylation.
D) chemiosmosis.
E) oxidation of NADH to NAD⁺.

Accepted Answer

The ATP generated during glycolysis is via substrate-level phosphorylation, which involves the transfer of a phosphate group from a high-energy molecule to ADP, forming ATP. This process is different from oxidative phosphorylation, which occurs during electron transport and involves the use of a proton gradient to generate ATP via chemiosmosis. Photophosphorylation similarly involves the use of a proton gradient, but it occurs during photosynthesis rather than glycolysis. The oxidation of NADH to NAD⁺ is a step in the electron transport chain and does not directly generate ATP during glycolysis.
