The best answer is ATP (Adenosine triphosphate).
Metabolism is a term referring to the overall processes by which energy is obtained by an organism. In man it begins with the digestion process, and ends with cellular respiration.
Food molecules are broken down into their monomer units through the digestive process. Carbohydrates are broken into glucose units. Glucose is taken in by cells and used in cellular respiration to produce ATP, which is the form of energy that cells use.
Cellular respiration involves three stages namely glycolysis , Krebs cycle and electron transport chain. From one molecule of glucose, the number of ATP molecules generated through cellular respiration is 36 to 38 molecules.

Answer:
The correct answer will be option A.
Explanation:
The atrioventricular valve is one of the four valves present in the heart the function of which is to stop the back flow of the blood from the ventricles to the atrium.
These valve opens and closes in response to the change in the pressure of the blood in atrium and ventricles. The valve opens when blood is pumped form the atrium to ventricles which causes the papillary muscles to relax while the valve closes when the ventricles push the blood to the arteries. This causes the papillary muscle to contract which causes the chordate tendineae to create tension ad close the valve.
Thus, option A is the correct answer.
