Question

Which of the following correctly describes a holoenzyme? Apoenzyme + cofactor Cofactor + prosthetic group Cofactor + coenzyme Coenzyme + prosthetic group

Answer 1

Answer:

aloenzyme

Explanation:

The enzyme that lacks a needed cofactor. A holoenzyme is an enzyme with its required cofactor; it functions the same as an enzyme. Holoenzymes can be composed of many smaller parts called subunits. Other proteins can attach to enzymes to form a holoenzyme complex.

Answer 2

Apoenzyme plus cofactor is the correct description of a holoenzyme.

option A

Explanation:

• following is a specific type of enzyme just like any other in language requires a cofactor to take part in a chemical reaction.

• Actually the core enzyme does not take part in the chemical reaction it is a biocatalyst which speeds up the the rate of the reaction by the lock and key hypothesis.

• the lock is acted by the holloenzyme which is completed when the  effector is attached.

• Then the reactant attach resulting in a morphological change in the reactants resulting in the formation of a product.
