AIn blood and lymph
BIn brain and retina
CIn skin and bone
DIn liver and muscle
Answer & Solution
Correct answer: D. In liver and muscle
1. Glycogen is a polymer of glucose and is the energy storage molecule in animals.
2. It is made and stored in both liver and muscle.
3. When adequate adenosine triphosphate is present, excess glucose is shunted into glycogen for storage.
4. Having a store means adenosine triphosphate can be produced for a longer period during exercise.
