Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Larger polymers are formed when monomers are joined together by a ____ reaction.
A
dehydration synthesis
B
digestion
C
hydrolysis
D
redox
Explanation: 

Detailed explanation-1: -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-2: -As additional monomers join via multiple dehydration synthesis reactions, this chain of repeating monomers begins to form a polymer. Complex carbohydrates, nucleic acids, and proteins are all examples of polymers that are formed by dehydration synthesis.

Detailed explanation-3: -Large biological molecules often assemble via dehydration synthesis reactions, in which one monomer forms a covalent bond to another monomer (or growing chain of monomers), releasing a water molecule in the process.

Detailed explanation-4: -Dehydration synthesis is the creation of larger molecules from smaller monomers where a water molecule is released. This can be used in the creation of synthetic polymers such as polyethylene terephthalate (PET), or the creation of large biological molecules such as carbohydrate polymers and triglycerides.

Detailed explanation-5: -Dehydration synthesis is a key step in the formation of polymers, large molecule chains formed by linking together multiple monomer units (via dehydration, of course). In biology, dehydration synthesis forms large polymers commonly referred to as biological macromolecules.
