Question

the formation of a complex carbohydrate is what type of reaction?
hydrolysis
decarboxylation
dehydration synthesis
phosphorylation

Explanation:

In dehydration synthesis, monomers combine to form polymers with the loss of a water molecule. Complex carbohydrates are formed when monosaccharides (simpler sugar monomers) join together and a water molecule is released in the process, as shown in the reaction where two sugar - like structures combine and produce water. Hydrolysis is the reverse (breaking down polymers with water), decarboxylation involves removal of a carboxyl group as carbon - dioxide, and phosphorylation involves addition of a phosphate group.

Answer:

C. dehydration synthesis
