Biology Question: Why are carbohydrates important molecules for energy storage?

Question

a. The C-H bonds found in carbohydrates store energy

b. The double bonds between carbon and oxygen are very strong

c. The electronegativity of the oxygen atoms means that a carbohydrate is made up of many polar bonds

d. They can form ring structures in the aqueous environment of a cell

I'm not sure about this one. I think the answer may be a. I would appreciate any help given. Thanks in advance.

Answer 1

a. The C-H bonds found in carbohydrates store energy

The C-H bond is a weak bond, which means that it stores a lot of energy. Carbohydrates are used for short term energy because they can be used for cellular respiration the fastest. Fats are used for long term because they have tons of C-H bonds. The draw back to fats, is that they have to first undergo beta oxidation cycles and other reactions so they can be used for cellular respiration. This process takes time.
