Enzymes that are always present, regardless of the amount of substrate, are <u>constitutive enzymes.</u>
We can define enzymes as a biological catalysts that are almost always proteins. It accelerates a particular chemical reaction in the cell. Each enzyme molecule found in a cell is unique and tailored to a particular chemical reaction.
Constitutive enzymes are one of the enzymes that are always present in constant amounts regardless of the physiological demand or the substrate concentration. They are continually produced because they are essential for preserving cellular functions or structure. They are also known as "housekeeping enzymes" because they are constantly formed and vital for maintaining the cell's regular metabolic processes. Production of constitutive enzymes is always unaffected by an inducer's presence or absence.
