The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, is a series of chemical reactions that takes place in the mitochondrial matrix. The overall goals of the Krebs cycle are to generate ATP, NADH, and FADH2 from carbohydrates through oxidative processes. During the Krebs cycle, acetyl-CoA derived from pyruvate is oxidized, releasing carbon dioxide and generating electron carriers to fuel the electron transport chain and produce more ATP through oxidative phosphorylation. The Krebs cycle occurs in two turns per glucose molecule and generates six NADH, two FADH2, and two GTP, which can ultimately produce between 25-32 ATP
