Question

Q3. A man does not eat for 2 days. The man feels very hungry. However, he can still walk around.
How does his body generate energy?​

Answer 1

Answer:

Though the man hasn't eaten for 2 days, he can still walk around thanks to the fats he might have consumed and the mitochondria. When a person consumes fat rich food sources, only some energy is used up and the rest is stored. When a need for this energy arises, the mitochondria converts this fat into ATP which is the energy currency of the body. This is the reason why the man has been able to walk though he hasn't eaten for 2 days.
