3. Explain the differences and similarities between substrate phosphorylation versus oxidative phosphorylation. Where in the cell does each take place. What coenzymes/cofactors are involved and what is the new ATP production of each mechanism? 4. Describe the Alanine Cycle in gluconeogenesis. What substrate is involved, and what tissue does it primarily occur in? When does the body utilize the Alanine cycle and why? 3.
