Question

which correctly shows the order of steps in aerobic cellular respiration?
glycolysis
citric acid cycle
pyruvic acid → acetyl - coa
electron transport chain
glycolysis
pyruvic acid → acetyl - coa
citric acid cycle
electron transport chain
glycolysis
citric acid cycle
electron transport chain
pyruvic acid → acetyl - coa

Explanation:

Aerobic cellular respiration first breaks down glucose through glycolysis. The pyruvic acid produced is then converted to acetyl - CoA. After that, acetyl - CoA enters the citric acid cycle, and finally, the electron transport chain uses the high - energy electrons from the previous steps to produce a large amount of ATP.

Answer:

The correct order is Glycolysis → Pyruvic acid → Acetyl - CoA → Citric acid cycle → Electron transport chain. So the middle option (Glycolysis → Pyruvic acid → Acetyl - CoA → Citric acid cycle → Electron transport chain) is correct.
