Isozymes: Definition, Occurrence and Characteristics | Enzymes

Isozymes: Definition, Occurrence and Characteristics! Definition of Isozymes: The enzymes that occur in a number of differ­ent forms and differ from each other chemically, immunologically and electrophoretically are called "Isoenzymes" or "isozymes". Occurrence of Isozymes: Isozymes are present in the serum and tissues of mammals, amphibians, birds, insects, plants and unicellular organisms. Examples: Isozymes of numerous dehydro­genases, and several oxidases, [...]

Enzymes Types: 4 Main Types of Enzymes

The following points highlight the four main types of enzymes. The types are: 1. Lactate Dehydrogenases 2. Transaminases 3. Creatine Kinase (CK or CPK) 4. Carbonic Anhydrase. Enzyme: Type # 1. Lactate Dehydrogenases: It is a glycolytic enzyme involved in the conver­sion of lactic acid to pyruvic acid and vice versa by the help of the coenzyme NAD. It exists [...]

Feedback Inhibition of Enzymes | Biochemistry

Learn about:- 1. Meaning of Feedback Inhibition 2. Control of Enzyme Synthesis –Induction 3. Control of Enzyme Synthesis -Repression and De-repression. Meaning of Feedback Inhibition: The changes in the concentration of substrates, coenzymes, activators or inhibitors affect the cata­lytic efficiency of an enzyme. Feedback inhibition inhibits the activity of an enzyme early in the biosynthetic pathway. In the biosynthetic reaction, [...]
