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.

The answer is it begins at the PYLORIC SPHINCTER and ends at
the ILEOCECAL SPHINCTER. The pyloric sphincter is a group of smooth muscle at
the joint between the pylorus of the stomach and the duodenum of the small
intestine. It plays a vital role in digestion, where it acts as a valve to
controls the flow of moderately digested food from the digestive to the small
intestine. Ileocecal is a sphincter muscle valve that split up the small
intestine and the large intestine.
