The Krebs Cycle produces a total of 2 ATP molecules per cycle.
Other notes about this stage include the following:
- The Krebs Cycle, also known as the citric acid cycle or tricarboxylic acid cycle, takes place in the mitochondria.
- It is the second stage of aerobic cellular respiration, following glycolysis.
- The cycle begins with the breakdown of a molecule of glucose, resulting in the production of NADH and FADH2, which carry high-energy electrons to the electron transport chain.
- Through a series of chemical reactions, the Krebs Cycle generates ATP, NADH, FADH2, and carbon dioxide.
- The cycle is called a "cycle" because it starts and ends with the same molecule, oxaloacetate, which is regenerated for the next cycle.
- The Krebs Cycle produces high-energy electron carriers (NADH and FADH2) that are crucial for the final stage of cellular respiration, the electron transport chain, in which the majority of ATP is produced.
