Answer:
D. dehydration synthesis
Explanation:
Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).
Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.
