What is the Krebs cycle also known as?

The Krebs cycle is commonly known as the citric acid cycle due to its production of citric acid as one of its key intermediates. This cycle is a central part of cellular respiration, where acetyl-CoA, derived from carbohydrates, fats, and proteins, is processed to generate energy. The process involves a series of reactions that lead to the release of carbon dioxide and the generation of high-energy electron carriers, such as NADH and FADH2, which are crucial for the subsequent electron transport chain.

Glycolysis, on the other hand, is the precursor metabolic pathway that breaks down glucose into pyruvate and occurs in the cytoplasm, while the Krebs cycle takes place in the mitochondria. The electron transfer cycle, commonly associated with oxidative phosphorylation, involves the transfer of electrons through a series of proteins, but is distinct from the Krebs cycle itself. Fermentation is an anaerobic process that generates energy without the use of oxygen, contrasting with the aerobic processes of glycolysis and the Krebs cycle. Therefore, the alternative names do not apply to the Krebs cycle as accurately as the citric acid cycle does.
