Enzymes are a kind of protein that is there in all types of living organisms. They are mostly secreted by a source and work as a catalyst in living organisms. They mainly guide several biochemical reactions happening inside organisms. They are majorly produced by plants, animals, bacteria, and fungus.
Regulation of enzyme activity is necessary to coordinate distinct metabolic processes. Enzymes can be managed by other molecules that either increase or reduce their activity. Molecules that increase the activity of an enzyme are commonly known as activators, while molecules that decrease the activity of an enzyme are known to be inhibitors.
