Cellular Respiration: Glycoysis

Glycolysis is the breakdown of glucose into pyruvate in the cytoplasm

ATP is required for the phosphorylation of glucose and intermediates during the energy investment stage of glycolysis This leads to the generation of more ATP during the energy pay off stage and results in a net gain of ATP

Dehydrogenase enzymes remove hydrogen ions and electrons and pass them to the coenzyme NAD forming NADH The hydrogen ions and electrons from NADH are passed to the electron transport chain on the inner mitochondrial membrane

In aerobic conditions pyruvate is broken down into an acetyl group that combines with coenzyme A forming acetyl coenzyme A
