Prior to entering the Krebs Cycle, each pyruvate molecule loses electrons, hydrogen ions, and a carbon, forming an energy-rich molecule of
|
|
Acetyl-CoA
|
|
|
Citrate
|
|
|
Oxaloacetate
|
|
|
Malate
|
Explanation:
Detailed explanation-1: -During the Krebs cycle, energy stored in pyruvate is transferred to NADH and FADH2, and some ATP is produced.
Detailed explanation-2: -In the process, electrons and a hydrogen ion are transferred to NAD to form high-energy NADH. Acetyl-CoA enters the Krebs cycle by combining with a four-carbon acid called oxaloacetic acid. The combination forms the six-carbon acid called citric acid. Citric acid undergoes a series of enzyme-catalyzed conversions.
