Multiple Choice
Which of the following statements best describes how monomers combine to form macromolecules?
A
Monomers spontaneously assemble into polymers without any chemical reaction.
B
Monomers are linked by ionic bonds during the process of polymerization.
C
Monomers combine through hydrolysis, which adds water to break bonds.
D
Monomers are joined together by dehydration synthesis, releasing water molecules as covalent bonds form.
Verified step by step guidance1
Understand the concept of monomers and macromolecules: Monomers are small, basic molecular units that can join together to form larger molecules called macromolecules, such as proteins, carbohydrates, and nucleic acids.
Learn about dehydration synthesis: Dehydration synthesis is a chemical reaction where monomers are covalently bonded together, and a water molecule is released during the process. This is the primary mechanism for forming macromolecules.
Contrast dehydration synthesis with hydrolysis: Hydrolysis is the opposite process, where water is added to break covalent bonds between monomers, breaking down macromolecules into smaller units.
Recognize the role of covalent bonds: During dehydration synthesis, monomers are linked by covalent bonds, which are strong chemical bonds formed by the sharing of electrons between atoms.
Apply the concept to the problem: The correct statement is that monomers are joined together by dehydration synthesis, releasing water molecules as covalent bonds form. This process is essential for building macromolecules in biological systems.
