Stage 1: Glycolysis

1

• Stage 1 Glycolysis
• Reactions occur in the cytosol. (10 steps)
• A 6-carbon glucose molecule is converted to two,
  3-carbon molecules of pyruvate.
• Two ATPs, two H2O and two NADHs are produced.
• Stage 2 into the mitochondria
• Reactions occur in the mitochondrial matrix.
• Each 3 carbon pyruvate is converted into a
  2-carbon group that combines with coenzyme A.
• Two CO2 and two NADH.

Stage 3 Krebs Cycle

• Reactions occur in the mitochondrion. (8 steps)
• Acetyl coenzyme A is degraded to carbon dioxide
  and energy is released
• four CO2 , six NADH, two FADH2 and two ATPs are
  produced
