Biochemistry of Enzymes Quiz

Enzymes are proteins that act as biological catalysts, accelerating biochemical reactions in the human body. They have various functions such as aiding in digestion and eliminating toxins.

The two identified sites within enzymes are the catalytic site, which is involved in catalysis, and the substrate binding site, where reactants called substrates bind to the enzyme.

If enzymes are found in high quantity in the blood serum, it indicates tissue damage, giving enzymes diagnostic value. Enzymes can also be used as drugs.
