  1. Aerobic Respiration Chapter 3.2 McGraw-Hill Ryerson Biology 12 (2011)

  2. Aerobic Respiration • Aerobic Respiration: catabolic pathways that require oxygen • Anaerobic respiration: catabolic pathways that exclude oxygen

  3. You are going to learn all of this Refer to pg 123 for a summarized table Refer to section 3.2 frequently to ensure knowledge of material

  4. Glycolysis: Be sure to refer to pg 124-125

  5. PyruvateOxiation: Refer to pg 126

  6. Krebs Cycle: Refer to pg 126-127

  7. Oxidative Phosphorylation: Pg 128

  8. Summary of Aerobic Respiration • Refer to pg 130 Glycolysis - Happens in cytoplasm - Yields 2 net ATP, and 2 NADH (but must enter mitochondria) Pyruvate Oxidation - Pyruvate is oxidized into acetyl-CoA and CO2 is released - Pyruvate molecules move from cytoplasm into mitrochondrion - NADH is formed per pyruvate (so 2 since 1 glucose can make 2 pyruvates) Krebs Cycle - Happens in Mitochondrial matrix - Yields 1 ATP per acetyl-CoA (2 acetyl-CoA is made from 1 glucose molecule) - 2 CO2 molecules released per acetyl-CoA (Thus 4 is released from 2 acetyl-CoA) - 3 NADH + 1 FADH2 released per acetyl-CoA (Thus 6 NADH and 2 FADH2 from 2 acetyl-CoA) Oxidative Phosphorylation - Happens in mitochondria and involves inner mitochondrial membrane - Uses the NADHs and FADH2s to form ATP molecules (3 per NADH, 2 per FADH2) *NADH from glycolysis must cross mitochondrial membrane in eukaryotes and thus is converted into FADH2
