If aerobic respiration follows glycolysis, pyruvate enters mitochondria. Glycolysis can also be followed by fermentation. Involves the transition reaction, the Krebs cycle, and the electron transport system. Takes place inside mitochondria. 50 and micro.
Mitochondrion has double membrane with an intermembrane space between outer and inner membrane.
Cristae are the inner folds of membrane that jut out into matrix. Matrix is the innermost compartment of a mitochondrion and is filled with gel-like fluid. Most ATP produced in cellular respiration is produced in mitochondria. Transition reaction connects glycolysis to the Krebs cycle. Reaction occurs twice for each original glucose molecule.
