"what is true of the breakdown of polymers inside living cells? " a. it is energetically unfavorable. b. it is associated with a negative change in free energy. c. it occurs without the need for enzymes.

 B. It is associated with a negative change in free energy.

Explanation:

A polymer is an organic compose made of many simple molecules that are repeating structural units called monomers. Examples of polymers are DNA, lipids, carbohydrates and proteins.

Polymers are broken down into monomers in a process known as hydrolysis, which is a reaction that splits the bond between monomers. During these reactions, the polymer is broken into many components.

This process of breakdown is called catabolic reactions, which, as it was said, is the break down of larger molecules into smaller molecules through the hydrolysis of its bonds. This reaction releases energy which was found in the bond between this monomers. And, when energy is released, there is a negative change in free energy. This means there is more free energy available for the cell to be used.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition
