Where Does Substrate-Level Phosphorylation Occur

Question

Where does substrate-level phosphorylation occur?
A)in glycolysis
B)in the citric acid cycle
C)in both glycolysis and the citric acid cycle
D)during oxidative phosphorylation
E)in glycolysis, the citric acid cycle and during oxidative phosphorylation

Accepted Answer

Substrate-level phosphorylation occurs in both glycolysis and the citric acid cycle, where a phosphate group is directly transferred to ADP to form ATP.
