Question

during which phases of cellular respiration is atp produced via substrate - level phosphorylation?
i dont know yet
glycolysis and pyruvate processing
glycolysis and the citric acid cycle
the citric acid cycle and the electron transport chain
pyruvate processing and the citric acid cycle

Explanation:

Cellular respiration has three main stages: glycolysis, the citric acid cycle (Krebs cycle), and the electron transport chain. Substrate - level phosphorylation occurs when a phosphate group is directly transferred from a substrate molecule to ADP to form ATP. In glycolysis, 2 ATP molecules are produced via substrate - level phosphorylation. In the citric acid cycle, 2 ATP (or GTP, which is readily converted to ATP) are produced via substrate - level phosphorylation.

Answer:

Glycolysis and the citric acid cycle
