Animals store a great deal more energy in fats than in glycogen. Fats also store more energy per gram than glycogen. Which is a reason for having some energy stored in glycogen, rather than using fats alone?
a. Glucose can be released very quickly from glycogen to provide energy
b. Glycogen is for longer-term energy storage for cases such as prolonged starvation
c. Glycogen can be transported in the blood more easily than fats
d. Energy released from glycogen is highly targeted for the use in particular tissues associated with the lymphatic system
