WebIn order for pyruvate, the product of glycolysis, to enter the next pathway, it must undergo several changes to become acetyl Coenzyme A (acetyl CoA). Acetyl CoA is a molecule that is further converted to oxaloacetate, which enters the citric acid cycle (Krebs cycle). The conversion of pyruvate to acetyl CoA is a three-step process. WebThe Citric Acid Cycle. In eukaryotic cells, the pyruvate molecules produced at the end of glycolysis are transported into mitochondria, which are sites of cellular respiration. If oxygen is available, aerobic respiration will go forward. In mitochondria, pyruvate will be transformed into a two-carbon acetyl group (by removing a molecule of ...

Acetyl-CoA - The Definitive Guide Biology Dictionary

The overall process of glycolysis is: Glucose + 2 NAD + 2 ADP + 2 Pi → 2 pyruvate + 2 NADH + 2 H + 2 ATP If glycolysis were to continue indefinitely, all of the NAD would be used up, and glycolysis would stop. To allow glycolysis to continue, organisms must be able to oxidize NADH back to NAD . How this is performed depends on which external electron acceptor is available. WebGlycolysis is the breakdown of glucose into two pyruvate molecules. This process does not require oxygen (it is anaerobic).
