Answer:
The correct answer will be option- B and C.
Explanation:
The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.
The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.
Thus, Option-B and C is the correct answer.
