During which of the following phases of cellular respiration does substrate-level phosphorylation take place? During which of the following phases of cellular respiration does substrate-level phosphorylation take place? the citric acid cycle only glycolysis and the citric acid cycle glycolysis only oxidative phosphorylation only

Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.

Explanation:

Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
