Krebs' Cycle

Oxaloacetate is the 'regenerator' of the Krebs Cycle, as it is regenerated at the end of the cycle to combine with Acetyl-CoA to start the cycle again.

Before entering the Krebs Cycle, pyruvate is oxidized to form Acetyl-CoA.

2 FADH₂ molecules are produced from 1 molecule of glucose during the Krebs Cycle.

The Krebs Cycle produces 2 ATP molecules.

The majority of usable energy after the Krebs Cycle is contained in NADH and FADH₂.

The primary function of the Krebs Cycle is to generate energy through the oxidation of Acetyl-CoA, producing NADH, FADH₂, and ATP.

One turn of the Krebs Cycle produces 3 NADH, 1 FADH₂, and 1 ATP (or GTP), along with 2 CO₂.

Acetyl-CoA is the starting substrate for the Krebs Cycle, combining with oxaloacetate to form citrate.

NADH and FADH₂ are crucial electron carriers that transport electrons to the electron transport chain, leading to ATP production.

The Krebs Cycle is a key component of aerobic respiration, occurring in the mitochondria and requiring oxygen to fully oxidize glucose.
