Why must the breakdown of molecules for energy in the body occur in several steps, rather than in one step?
About half of the free energy stored in a fatty acid is converted to free energy stored in ATP, wheredid the rest of the free energy go?
Glycogen is not as reduced as fatty acids are and consequently are not as energy rich. Why isn’t all excess fuel stored as fatty acids rather than as glycogen?
