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.
Glycolysis Out of the cytoplasm it goes into the Krebs cyclewhere the acetyl CoA. It then mixes with CO2and makes 2 ATP, NADH, and FADH. Fromthere the NADH and FADH go into the NADHreductase, which produces the enzyme. TheNADH pulls the enzyme's electrons to sendthrough the electron transport chain.
