Your heart is the pump for your circulatory system. It is made of muscle and contracts in order to pump blood through your body. The arteries and veins are the roadways through which blood is transported to all parts of your body. Arteries carry oxygen-rich blood from your heart to the rest of your body.Veins return the blood to the heart after the oxygen has been used. Your body needs oxygen in order to function.he arteries and veins are the roadways through which blood is transported to all parts of your body.

This process recycles NADH to NAD + so that NAD + can be reused in glycolysis. At the end of the ETC, water (H 2 O) and ATP is made. Depending on how many NADH molecules are available, the electron transport chain makes a total of 32 or 34 ATP.
Full Answer. Oxidation of glucose, also known as glycolysis, is the process which releases energy stored in glucose by combining it with oxygen. During glycolysis, carbon, hydrogen and oxygen in one molecule of glucose recombine with six molecules of oxygen. The products of one molecule in glucose in glycolysis include six molecules of carbon dioxide, six molecules of water, and energy molecules called ATP and NADP.
