I. Glucose + 6 O2 6CO2 + 6H20 + ENERGY! II. Glycolysis a. Takes place in the cytoplasm b. 10 enzyme catalyzed reactions c. d. Energy investing: 2 ATP are needed to give us 2 G3P molecules (a 3C molecule) e. Energy harvesting: 2 NADH + 4 ATP are produced by substrate level phosphorylation. III. Anaerobic respiration: a. Lactic Acid fermentation: NADH + H+ is oxidized to NAD+, so it can be used again in glycolysis. i. Pyruvate (3C) lactic acid (lactate) also (3C) b. Alcoholic fermentation: NADH + H+ is oxidized to NAD+, so it can be used again in glycolysis. i. Pyruvate (3C) Ethanol + CO2 IV. Pyruvate Oxidation **from here on I’m only using 1 pyruvate, so to find the total # of everything, multiply by 2) a. Pyruvate + CoA+ NAD+ Acetyl CoA + CO2 + NADH + H+ b. We need the energy in Acetyl CoA in order to start the Citric Acid Cycle V. Citric Acid Cycle a. Takes place in the matrix b. 8 reactions c. Products (outcome): 2CO2 + 1ATP+ FADH2 + 3 NADH + H+ (Oxaloacetate is regenerated)
