What Role Do Enzymes Play in Biological Activities?
Enzymes are crucial in mediating the biological activities of substances. They can activate or deactivate chemicals, altering their toxicity. For instance, the liver enzyme cytochrome P450 metabolizes many drugs and chemicals, transforming them into more water-soluble forms for excretion. However, this process can sometimes result in the formation of reactive metabolites that are more toxic than the parent compound.
