- A Fats contain a greater proportion of oxygen atoms per carbon skeleton
- B Fats are more highly reduced (more C-H bonds)
- C Fats are built from longer unbranched carbon chains than glucose polymers
- D Fats are insoluble in water and stored within dedicated adipocyte vacuoles
Correct answer: B. Fats are more highly reduced (more C-H bonds)
Explanation: Fats have a higher degree of reduction (more C-H bonds, less C-O bonds) compared to carbohydrates. More reduced carbon means more electrons available for the ETC, yielding more ATP.
