The first step of the Krebs cycle involves the condensation of acetyl-CoA and oxaloacetate to form citrate, catalyzed by the enzyme citrate synthase. This reaction is irreversible and initiates the series of reactions that ultimately lead to the production of energy-rich molecules like ATP.

What is a chemical equation for Krebs cycle?

The Krebs cycle is a series of chemical reactions that occur in cells to generate energy. A simplified chemical equation for the Krebs cycle is: Acetyl-CoA + 3NAD+ + FAD + GDP + Pi + 2H2O ---> 3NADH + FADH2 + GTP + 2CO2 + CoA + 3H+ This equation summarizes the conversion of acetyl-CoA into carbon dioxide and energy-carrying molecules such as NADH and FADH2.
