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. Pyruvate Oxiation: Refer to pg 126

6. Krebs Cycle: Refer to pg 126-127

8. Oxidative Phosphorylation: Pg 128

10. 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
