Question

Which one is a conjugate enzyme?
A. Succinate dehydrogenase
B. Urease
C. Trypsin
D. Both A and B

Answer 1

Hint: Enzymes are the biomolecules that help in increasing the rate of biochemical reactions. These are colloidal organic macromolecules that are mostly proteinaceous in nature except ribozyme.

Complete answer:
Succinate dehydrogenase
> Conjugated enzymes are the enzymes containing a conjugated group or prosthetic group attached to it. For example, Succinate dehydrogenase is an enzyme present in the inner mitochondrial membrane that catalyzes the oxidation of succinate to fumarate. This enzyme has FMN (Flavin mononucleotides) or FAD (Flavin adenine dinucleotide) molecule as a prosthetic group.
> Another example of conjugate protein is nucleoprotein that has nucleic acid attached as a prosthetic group.
> Prosthetic groups are the non-protein part or the group that gets permanently attached to the enzyme. These are mostly organic factors but some are metallic also like iron, porphyrin of the cytochromes.
Urease
Urease is an enzyme found in bacteria, fungi, algae, plants and some invertebrates that catalyzes the hydrolysis of urea forming ammonia and carbon dioxide.
Trypsin
Trypsin is an enzyme that helps in the digestion process in humans in the small intestine. It is a proteolytic enzyme that is produced by the pancreas in an inactive form called trypsinogen.

Note: Conjugated or compound enzymes consist of cofactors that are associated with the apoenzymes of the enzyme. It can be either a prosthetic group or a coenzyme.
Coenzymes are associated with apoenzymes only during the course of catalysis and they are always organic in nature. They are generally derived from the vitamins and they act as the carriers of chemical groups or atoms or electrons.
