Cellular Respiration and Fermentation
Citric Acid Cycle
Acetyl (2C) + Oxaloacetate (4C) = Citric Acid
Net yield of 1 turn: 2 CO2, 3 NADH, 1 FADH2, & 1 ATP
Glycolysis (10 steps)
Cleavage
Steps 4-5
6 carbon molecule broken
Energy Liberation
Steps 6-10
2 NADH & 4 ATP
Energy Investment
Steps 1-3
2 ATP hydrolyzed
Fermentation
Organic molecules are broken down without any net oxidation
Produces less ATP then phosphorylation
Breakdown of Pyruvate
Broken down by pyruvate dehydrogenase.
Net yield: 2 acetyl, 2 Co2 & 2 NADH
Oxidative Phosphorylation
Requires oxygen
Net yield: 1/2 O2 + 2H = H2O
Involves electron transport chain
Up to 30 ATPs
Oxidation by ETC
H+ electrochemical gradient
Series of redox reactions
Two strategies
O2 as final electron acceptor in electron transport chain =
Anaerobic respiration
ATP only via substrate-level phosphorylation =
Fermentation
ATP synthase
Harnesses free energy
Protons can only pass through ATP synthase.
