Verified step by step guidance

Understand the question: The problem asks which process links monosaccharide units to form carbohydrate polymers. This involves identifying the biochemical mechanism responsible for polymer formation.

Recall the concept of dehydration synthesis: Dehydration synthesis, also known as a condensation reaction, is a process where two molecules are joined together by removing a water molecule. This is a key mechanism in forming carbohydrate polymers.

Relate dehydration synthesis to carbohydrates: In the case of carbohydrates, monosaccharides (simple sugars) are linked together via glycosidic bonds. These bonds are formed during dehydration synthesis when a hydroxyl group (-OH) from one monosaccharide and a hydrogen atom (H) from another are removed, resulting in the release of a water molecule (H₂O).

Compare dehydration synthesis with other processes: Hydrolysis is the reverse of dehydration synthesis, breaking down polymers into monomers by adding water. Phosphorylation involves adding a phosphate group, and oxidation involves the loss of electrons. Neither of these processes is responsible for linking monosaccharides into polymers.

Conclude the reasoning: Based on the biochemical mechanism, dehydration synthesis (condensation reaction) is the correct process for linking monosaccharide units to form carbohydrate polymers.
