Question

aerobic respiration uses the citric acid cycle, oxidative phosphorylation, and another step. what is the missing step? carbon fixation glycolysis the light dependent reaction the calvin cycle

Explanation:

Aerobic respiration has three main stages: glycolysis (breaks down glucose into pyruvate), the citric acid cycle (further breaks down pyruvate - derived molecules), and oxidative phosphorylation (generates ATP using electron transport). Carbon fixation, light - dependent reactions, and the Calvin cycle are part of photosynthesis, not aerobic respiration. So the missing step in aerobic respiration is glycolysis.

Answer:

B. glycolysis
