BIO Macromolecules quiz
Which of the following best summarizes the relationship between dehydration reactions and hydrolysis? a. Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers. Hydrolysis creates monomers, and dehydration reactions break down polymers . ANS: B PTS: 1 TOP: Self-Quiz Questions. In hydrolysis, a large molecule is broken down into smaller components, with the addition of a molecule of water. The digestion of foods is an example of. Quiz over chapters 5 and 6 in Campbell and Reece book. best summarizes the relationship between dehydration reactions and hydrolysis? Dehydration reactions accur in plants, and hydrolysis happens in animals.
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. In the dehydration synthesis reaction depicted above, two molecules of glucose are linked together to form the disaccharide maltose.
In the process, a water molecule is formed. At the same time, the monomers share electrons and form covalent bonds. As additional monomers join, this chain of repeating monomers forms a polymer.
Different types of monomers can combine in many configurations, giving rise to a diverse group of macromolecules. Even one kind of monomer can combine in a variety of ways to form several different polymers: During these reactions, the polymer is broken into two components: In the hydrolysis reaction shown here, the disaccharide maltose is broken down to form two glucose monomers with the addition of a water molecule.
These reactions are similar for most macromolecules, but each monomer and polymer reaction is specific for its class.
For example, in our bodies, food is hydrolyzed, or broken down, into smaller molecules by catalytic enzymes in the digestive system. This allows for easy absorption of nutrients by cells in the intestine. Each macromolecule is broken down by a specific enzyme. For instance, carbohydrates are broken down by amylase, sucrase, lactase, or maltase.

Proteins are broken down by the enzymes pepsin and peptidase, and by hydrochloric acid. In biology, these processes involve the formation of Polymers, these are molecules covalently linked together. These are formed when water is removed from a chemical equation then monomers small molecules bond together. In order to break the bonds, water must be added to the equation.
To further understand this, detailed information regarding the difference between hydrolysis and dehydration synthesis is discussed below. Hydrolysis Hydrolysis means separating with the use of water.
In Chemistry, Hydrolysis is a chemical reaction with water, in which a macromolecule is separated into smaller molecules.
Difference Between Hydrolysis and Dehydration Synthesis
On the other hand, in Biology, this process involves water to split polymers into monomers. The bottom line is Hydrolysis occurs when water is added to the equation to break it down or separate it.
In our bodies, Hydrolysis is the main process to release energy. When we eat food, it is digested or broken down into substances so the body can absorb it and convert it to energy.
Synthesis of Biological Macromolecules - Biology LibreTexts
Foods, having complex molecules are broken down into simple molecules. When energy is needed for biosynthesis, ATP is hydrolyzed and stored energy is released for utilization. Dehydration Synthesis Dehydration means to take away water, and synthesis means to build or create something.
