A)in glycolysis
B)in the Krebs cycle
C)in both glycolysis and the Krebs cycle
D)during oxidative phosphorylation

Quizplus · Accepted Answer

Substrate-level phosphorylation occurs in both glycolysis and the Krebs cycle, where ATP is directly synthesized from ADP and a phosphate group using the energy released from specific reactions within these pathways.
