What happens during citric acid cycle?

Answer 1

The Citric Acid Cycle (Kreb's or Tri-carboxylic Acid Cycle) is the part of cellular respiration in which Pyruvic Acid is processed until a glucose molecule is made. * This 2-carbon fragment is donated to a molecule of oxaloacetic acid. * The resulting molecule of citric acid (which gives its name to the process) undergoes the series of enzymatic steps shown in the diagram. * The final step regenerates a molecule of oxaloacetic acid and the cycle is ready to turn again. Summary: * Each of the 3 carbon atoms present in the pyruvate that entered the mitochondrion leaves as a molecule of carbon dioxide (CO2). * At 4 steps, a pair of electrons (2e-) is removed and transferred to NAD+ reducing it to NADH + H+. * At one step, a pair of electrons is removed from succinic acid and reduces FADto FADH2. The electrons of NADH and FADH2 are transferred to the electron transport chain.

Answer 2

The production of ATP

The citric acid cycle is a central metabolic pathway that completes the oxidative degradation of fatty acids, amino acids, and monosaccharides. During aerobic catabolism, these biomolecules are broken down to smaller molecules that ultimately contribute to a cell's energetic or molecular needs.
