1) how the sequential oxidation, hydration, and oxidation in beta-oxidation is parallel to the succinate to OAA part of the TCA cycle.
2) A statement in the notes goes as such: “the E0’ of FAD is more positive than the E0’ of NAD “explain what this means in terms of reduction or oxidation and how it applies to elections affinity?
Answer 2:- Eo is known as standard of redox potential. Eo is considered as zero for solution containing 1 M hydrogens atoms in equilibrium with hydrogen gas. This is taken as reference value for Eo. If a compound In a solution has a greater tendency to give up electrons than H2, it is considered to have negative standard of redox potential. Similarly, if the compound has tendency to accept electrons, it is considered to have positive standard of redox potential. FAD has Eo of -0.05, while NAD has Eo of -0.32, thus the Eo of FAD is more positive than Eo of NAD.
