WebThis reaction releases the CoA group resulting in the formation of a six-carbon molecule called citrate. Step 2 – In the next step, citrate gets converted into an isomer of citrate called the isocitrate. This is a two-step process and occurs simultaneously. A citrate molecule first loses a water molecule and then gains one to form isocitrate. WebThe TCA cycle is a crucial metabolic mechanism that produces reducing equivalents in the form of NADH and FADH2 and energy in the form of ATP. The cycle is started by adding acetyl-CoA to the pathway and supplying a substrate for subsequent events in the production of citrate from oxaloacetate and acetyl-CoA.
