Which stage of cell respiration produces co2:
a. glycolysis
b. fermentation
c. citric acid cycle
d. electron transport chain

C : Citric acid Cycle

Explanation: Cell respiration or Cellular respiration is term by which food energy is converted into the usable energy source Adenosin triphosphate ( ATP ). Cell respiration is a set of metabolic reactions , processess and pathways.

Citric acid cycle is set of reactions by which maximum amount of CO2 is released. In Citric acid cycle acetyl CoA undergoes releactions in presence of necessary enzymes by which CO2 is released .
