Detailed explanation-1: -Enzymes are a specialized class of proteins responsible for catalyzing chemical reactions within the cell and thus are ideal drug targets.

Detailed explanation-2: -Enzymes Are Powerful and Highly Specific Catalysts This is the case for the large and very important class of proteins called enzymes. As described in Chapter 2, enzymes are remarkable molecules that determine all the chemical transformations that make and break covalent bonds in cells.

Detailed explanation-3: -The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-4: -The highly specialized proteins which catalyse biological reactions are known as enzymes.

Detailed explanation-5: -In biology, some enzymes are highly specialized and catalyze specific reactions with few or only one substrate while other enzymes are promiscuous and can catalyze reactions using a variety of substrates.
