2. Metabolic Pathways

3. Glycolysis Investment phase ATP added into system Payoff phase
ATP produced
Substrate level phosphorylation
Net gain- 2 ATP
2 NADH
Pyruvate
Cytoplasm

4. Glycolysis

7. Pyruvate Dehydrogenase
Gateway into Krebs
Oxidative decarboxylation
Produces NADH
Produces CO2
Produces acetyl Co A
Matrix of mitochondrion

8. Krebs Acetyl group enters Oxaloacetic acid Citric acid
2 oxidative decarboxylatons per cycle
2 ATP by substrate level phosphorylation
6 NADH
2 FADH
Matrix of mitochondrion

9. Electron Transport Chain
Embedded in inner membrane of mitochondrion
Proton gradient produced
Proton gradient drives ATP synthase
O2 as terminal electron acceptor
NADH – 3 ATP
FADH – 2 ATP
