Question

question 28
what is a common chemical reaction mechanism by which cells make polymers from monomers?
decreasing the ph
hydrolysis reactions
dehydration reactions
the formation of ionic bonds between monomers

Explanation:

Dehydration reactions, also known as condensation reactions, are common in cells for polymer formation from monomers. In a dehydration reaction, a water molecule is removed as a covalent bond forms between two monomers. Hydrolysis is the reverse process, breaking polymers into monomers. Changing pH doesn't directly make polymers from monomers, and ionic - bond formation between monomers isn't the main mechanism for polymer synthesis in cells.

Answer:

C. dehydration reactions
