Citric Acid Cycle in Biochemistry: Steps, Enzymes, and Regulation via ADP/ATP Feedback
The Citric Acid Cycle (TCA cycle) is a central metabolic pathway in biochemistry characterized by its primary objective: the oxidation of acetyl-CoA to generate reduced electron carriers, specifically NADH and FADH2, for subsequent oxidative phosphorylation. This mechanism functions under strict allosteric regulation where ADP acts as an obligate stimulant signaling low energy status, while ATP, NADH, and FADH2 serve as negative feedback inhibitors preventing unnecessary substrate processing when cellular energy levels are sufficient.
