Question

modeling aerobic cellular respiration
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 begins with glycolysis, which breaks down glucose into pyruvate. Then pyruvate is converted to acetyl - CoA. After that, the citric acid cycle (Krebs cycle) occurs, and finally, the electron transport chain.

Answer:

The second diagram (Glycolysis → Pyruvic acid → Acetyl - CoA → Citric acid cycle → Electron transport chain) is correct.
