Aerobic respiration and fermentationNAD+ vs NADH - answer oxidized form: NAD+
reduced form: NADH
FAD vs FADH2 - answer oxidized form: FAD
reduced form: FADH2
stages of cellular respiration - answer glycolysis
fermentation
cellular respiration
citric acid cycle
Glycolysis process - answer occurs in cytoplasm and does not require oxygen.
Glycolysis inputs and outputs - answer input: 1 glucose
2 ATP
2 NAD+
output: 4 ATP
2 NADH
2 pyruvate
fermentation process - answerconsists of glycolysis and reactions that regenerate
NAD+. Regeneration occurs by transferring electrons from NADH to pyruvate or
derivatives of pyruvate. The NADS+ can then be reused to oxidize sugar by glycolysis.
(conversion of pyruvate to Ethanol or Lactic acid). Occurs in cytoplasm and does not
require oxygen.
fermentation inputs and outputs - answerif no O2, pyruvate turn into 2 ethanol or 2
lactate
- regenerate NAD+ to repeat glycolysis
- does not need O2
- Output: 2 NAD+ & 2 ATP
the citric acid cycle process - answer1. 8 separate reactions, each catalyzed by a
different enzyme
2. completes the oxidation of glucose to CO2
3. Cycle begins and ends with a 4 C compound, oxlocacetate
4. for each acetyl-CoA molecule entering the cycle, the following are produced: 1 ATP.
3 NADH. 1 FADH2. 2 CO2.
Occurs inside the mitochondrial matrix in eukaryotes
