There are 4 organic molecules that we studied, lipids, carbohydrates, amino acids, and proteins (nucleic acids). all of them are polymers except lipids. dehydration reaction is the chemical reaction that links the together by removing a form one monomer and an from a second molecule creating a between these molecules. the and the will be bonded as well to form a water molecule. on the other hand, is a chemical reaction that down introducing a water molecule and breaking the covalent between the monomers in the polymers.

Dehydration reaction is the chemical reaction that links the MONOMERS together by removing a HYDROGEN ATOM form one monomer and an OH GROUP from a second molecule creating a COVALENT BOND between these molecules. The H ATOM and the OH GROUP will be bonded as well to form a water molecule. On the other hand, HYDROLYSIS is a chemical reaction that BREAK down POLYMERS introducing a water molecule and breaking the covalent between the monomers in the polymers.

Explanation:

Carbohydrates, proteins and nucleic acids are polymers of simpler sugars, amino acids and nucleotides respectively. Monomer molecules are joined together to form a polymer by dehydration reactions and a water molecule is released. On the other hand, hydrolytic reactions break down polymers into monomers by adding water molecules to them.

For example, a dehydration reaction joins two amino acids together by a peptide bond (a specific type of covalent bond that joins the amino acids) to form a dipeptide. During the reaction, one amino acid loses an H atom and the other loses its OH group to release a water molecule.

Breakdown of proteins into amino acid occurs by hydrolytic reactions in which water molecules are added to amino acids to breakdown the peptide bonds between them.

an active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. the substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme
