Multiple Choice
In glycolysis, ATP molecules are produced directly by which process?
A
ATP synthase-driven chemiosmosis across the inner mitochondrial membrane
B
Oxidative phosphorylation in the electron transport chain
C
Direct transfer of phosphate from NADH to ADP
D
Substrate-level phosphorylation
Verified step by step guidance1
Understand that glycolysis is a metabolic pathway that breaks down glucose into pyruvate, producing ATP in the process.
Recognize that ATP production can occur via two main mechanisms: substrate-level phosphorylation and oxidative phosphorylation.
Recall that oxidative phosphorylation involves ATP synthase and chemiosmosis in the mitochondria, which is not part of glycolysis but rather occurs in the electron transport chain.
Identify that substrate-level phosphorylation is the direct transfer of a phosphate group from a phosphorylated intermediate to ADP, forming ATP, and this occurs during glycolysis.
Conclude that in glycolysis, ATP molecules are produced directly by substrate-level phosphorylation, not by ATP synthase-driven chemiosmosis or oxidative phosphorylation.
