Q

What is more efficient than glucose?

A
  • Fats are a more efficient food source because they are more reduced
17
Q

The more (oxidized or reduced) a carbon atom is, the more free energy is released upon oxidation

A
  • Reduced
18
Q
  • Activated carriers are often derived from?
A
  • Vitamins
19
Q

What is the difference between NAD+ and NADP+?

A
  • NAD+ is used in catabolic rxns

- NADP+ is used in anabolic rxns and has the 2’ hydroxyl phosphorylated
