Question

Why we will not get any energy if we try to eat coal?

• A. Because coal is not edible
• B. We do not have the enzymes which are needed for the breakdown of coal
• C. Coal cannot be digested
• D. Coal is a fuel it cannot be eaten

Answer 1

The correct option is B

We do not have the enzymes which are needed for the breakdown of coal

Any material or substance that we eat as food will only provide us energy when our body has enzymes to break the complex molecules of that substance into simpler ones to release energy. In case of coal, we do not have the enzymes to breakdown it.
