Question

in animal cells, glycogen is broken down to release energy to help with muscle contraction. a polymer like glycogen is broken down in a process called hydrolysis, where a water molecule breaks, or lyses, a bond in the polymer to make monomers. the model shows a hydrolysis reaction. complete the sentence. during a hydrolysis reaction, ____ are broken down into __ to release ____.

Explanation:

1. From the text: "A polymer like glycogen is broken down in a process called hydrolysis, where a water molecule breaks, or lyses, a bond in the polymer to make monomers." Also, the diagram shows a polymer (two sugar units linked) reacting with water to form two monosaccharide units. And the context of glycogen (a polymer) breaking down to release energy for muscle contraction.
2. So, during hydrolysis, polymers (like glycogen, or the polymer in the diagram) are broken down into monomers (the single sugar units) to release energy (as stated in the text about glycogen helping muscle contraction by releasing energy).

Answer:

During a hydrolysis reaction, \(\boldsymbol{\text{polymers}}\) are broken down into \(\boldsymbol{\text{monomers}}\) to release \(\boldsymbol{\text{energy}}\).
