Lecture 4.5: Krebs Cycle
Glycolysis occurs in all cells, and therefore can lay claim to being the heart of energy metabolism in all cells. However, it’s ability to transfer energy from organic compounds to ATP is very limited. Most of the available free energy that could be used to make ATP is wasted. However, when oxygen is available, and cell possess the metabolic pathways to utilize it, a great deal more energy can be extracted from compounds like glucose and used to regenerate ATP. Here, we study those metabolic pathways.
