How Would You Explain The Connection Between Glucose Entering The Body and Energy Created By The Body To A Friend?

Glycolysis was the first biochemical pathway elucidated. In glycolysis, one molecule of glucose, which is a six - carbon compound, is converted to frucotse - 1,6 - bisphosphate. This compound eventually gives rise to two molecules of pyruvate, which is a three - carbon compound. The glycolytic pathway involves many steps that include the reactions in which metabolites of glucose are oxidized. Each reaction in glycolysis is catalyzed by an enzyme specific for that reaction. In each of two other reactions, one molecule of ATP is hydrolyzed for each molecule of glucose metabolized; the energy released in the hydrolysis of these two ATP molecules makes coupled endergonic reactions possible. In each of two other reactions, two molecules of ATP are produced by phosphorylation of ADP for each molecule of glucose. At the end of glycolysis, there is a total of 32 ATP produced for the body to use as energy. This process is ongoing and is essential for life.
