Krebs Cycle (citric acid cycle)
enzymes process pyruvate releasing CO2 and producing NADH and acethl CoA. then the cycle starts with a two carbon acetyl group being added to a four carbon compound, forming citrate, which is degraded back to the starting four carbon compound. for each turn of the cycle. 2 CO2 are released.
the energy yeild is 1 ATP, 3 NADH, 1FADH2
