We have to eat in order to carry out all of our bodily processes. what type of energy trasformation is taking place when we use that digested food in order to run? a) thermal to chemical b) chemical to mechanical c) mechanical to chemical d) electrical to chemical

B) chemical to mechanical

Explanation:

Let us understand how digestion works in our body.

When we intake food which has chemical energy it comes into contact with acids and enzymes which breakdown the constituents into a form in which the body can use it. When carbohydrates in the food interact with the acids and enzymes they are converted to glucose. This glucose is then absorbed by the stomach and small intestines. The glucose is then released to the bloodstream.

When we need to use energy the glucose is the fuel that provides this energy.
