Krebs Cycle and Cellular Respiration

Cellular respiration is a critical process in which cells convert glucose and oxygen into energy. This process occurs in various stages, primarily in the cytoplasm and mitochondria of the cell. One of the main components of cellular respiration is the Krebs cycle, which plays a key role in breaking down acetyl-CoA into carbon dioxide and high-energy electron carriers, such as NADH and FADH₂.

After the Krebs cycle, these high-energy electron carriers enter the electron transport chain, leading to the production of ATP, the main energy currency of the cell. Understanding the role of these processes in energy metabolism is crucial for comprehending overall biological functions.
