Substrate -level phosphorylation accounts for approximately 100% of the ATP formed by the reactions of glycolysis.
The direct transfer of a phosphate group to ADP to form ATP is known as substrate-level phosphorylation. It accounts for all of the ATP produced by glycolysis reactions. The first substrate-level phosphorylation occurs when 1,3-diphosphoglyceraldehyde is converted to 1,3 diphosphoglyceric acid and 2 NADH2, resulting in the formation of 6 ATP. Substrate-level phosphorylation converts the 1, 3-diphosphoglyceric acid to 3 phosphoglyceric acid, which produces 2 ATP. The second substrate-level phosphorylation takes place when phosphoenolpyruvic acid is converted to pyruvic acid, which results in the formation of two ATP molecules.

Explanation: The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.
