Krebs Cycle

Krebs Cycle

Krebs Cycle Overview Krebs cycle is a cyclical process to: Also known as the citric acid cycle and the tricarboxylic acid cycle (TCA).

Krebs Cycle

Krebs Cycle: Step by Step join 2 carbon molecule with a 4 carbon molecule rxn type: enzyme: energy:

Krebs Cycle: Step by Step rearrangement of atoms with the help of H2O rxn type: enzyme: energy:

Krebs Cycle: Step by Step synthesis of CO2 and NADH rxn type: enzyme: energy:

Krebs Cycle: Step by Step CO2 release and energy molecule formation rxn type: enzyme: energy:

Krebs Cycle: Step by Step ADP phosphorylation to ATP rxn type: enzyme: energy:

Krebs Cycle: Step by Step FADH2 (energy molecule) formation rxn type: enzyme: energy:

FAD / FADH2 FAD – flavin adenine dinucleotide (oxidized form) FADH2 – flavin adenine dinucleotide (reduced form)

Krebs Cycle: Step by Step rearranging the molecule for the next reaction rxn type: enzyme: energy:

Krebs Cycle: Step by Step energy molecule formation & recreating molecules for Krebs cycle rxn type: enzyme: energy:

Krebs Cycle Summary two cycles of Krebs for EACH glucose molecule acetyl-CoA  oxaloacetate (per cycle) ___ CO2 released (per cycle) ___ NADH produced (per cycle) ___ FADH2 produced (per cycle) ___ ATP produced (per cycle)

Krebs Cycle: Big Picture Perspective Many of the components of Krebs cycle are used in many other types of metabolic processes.
