Final answer:
Dehydration synthesis is an endergonic process that requires energy to link monomer molecules together, releasing water for each bond.
Step-by-step explanation:
Dehydration synthesis (also known as condensation) is an energetically unfavorable process, therefore it is endergonic and requires energy. In a dehydration synthesis reaction, monomer molecules are linked together with the release of a water molecule for each bond formed. To form these bonds, energy needs to be supplied because the reaction involves making complex molecules from simpler ones. An example of this process is the formation of polymers like proteins or starches from monomers like amino acids or glucose. The energy required often comes from molecules like ATP (Adenosine Triphosphate), which, when hydrolyzed, release energy that can drive the endergonic reaction of dehydration synthesis.
