|
|
Hydrolysis creates monomers, and dehydration reactions break down polymers.
|
|
|
Dehydration reactions can occur only after hydrolysis.
|
|
|
Dehydration reactions assemble polymers, and hydrolysis breaks down polymers.

Detailed explanation-1: -(5.0 points) Which of the following best summarizes the relationship between dehydration reactions and hydrolysis? Dehydration reactions ionize water molecules and add hydroxyl groups to polymers; hydrolysis reactions release hydroxyl groups from polymers.
Detailed explanation-2: -Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.
Detailed explanation-3: -Which of the following best summarizes the relationship between condensation (dehydration) reactions and hydrolysis? a. Condensation reactions assemble polymers and hydrolysis breaks them down.
Detailed explanation-4: -Dehydration Synthesis The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”
Detailed explanation-5: -Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water, ” a reaction in which a water molecule is used during the breakdown. During these reactions, the polymer is broken into two components.
