Document Summary
Traditionally, metabolic reactions have been divided into anabolic and catabolic reactions. Another oversimplification is the statement that processes are irreversible. If a reaction has a delta g and an equilibrium constant associated with it, this is an affirmation that reactions are basically reversible. The direction in which an equilibrium may lie, however, will be determined one directionally. Atp gains its high energy from phosphoanhydride bonds. The hydrolysis of such high energy bonds is responsible for high energy release. Therefore, atp is coupled for reactions that are energetically unfavorable. The glycolytic pathway can be carried out in the presence or absence of oxygen and yields a final product of acetyl-coenzyme a (acetyl-coa), which is fed into the second part of a carbohydrate catabolic pathway. Good fuel is highly reduced and soluble in water. Reduction of compounds to make atp is associated with oxidation of intermediates in carbohydrate catabolism.
