The Krebs cycle is also known as what?

The Krebs cycle is correctly known as the Citric Acid Cycle. This cycle is a crucial component of cellular respiration, taking place in the mitochondria of cells. It is responsible for the oxidation of acetyl-CoA to carbon dioxide and plays a significant role in generating energy in the form of ATP, as well as reducing equivalents (NADH and FADH2) that are used in the electron transport chain.

The term "Citric Acid Cycle" comes from the first product formed in the cycle, citric acid (or citrate), which is produced when acetyl-CoA combines with oxaloacetate. This cycle also serves as a metabolic hub, connecting not only the metabolism of carbohydrates but also lipids and proteins, facilitating the catabolism and anabolism of various biomolecules.

In contrast, other options like the Glycolytic cycle, Fatty acid cycle, and Protein cycle do not accurately describe the Krebs cycle; they refer to distinct metabolic pathways involved in carbohydrate breakdown, fatty acid metabolism, and protein metabolism, respectively. Understanding this distinction is essential for grasping the interconnectedness of various pathways in cellular metabolism.
