Document Summary
Glucose is preferred molecule for atp production. One molecule of atp is produced from glycolysis. Nadh (an electron carrier) is created and carries electrons to the proton gradient at the end. 2 pyruvate molecules are created for every one glucose molecule. This is because glucose has 6 carbons, which split into two molecules of 3 carbons each. Pyruvate processing releases co2 and more nadh. Releasing co2 allows the molecule to fit into the citric acid cycle because a carbon was taken out (was too large with 3 carbons) Acetyl coa (a 2 carbon molecule) is produced from each pyruvate. The citric acid cycle is continuous (no end point) Atp is produced in this cycle (oxidative phosphorylation) Glycolysis is a series of 10 chemical reactions. Enzymes are used to lower activation energy, then atp is used to begin glycolysis (no heat involved in glycolysis) Start with a glucose molecule, give it atp (phosphorylate it) to give it energy.
