Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
Which statement correctly describes the relationship between enzymes, coenzymes, and prosthetic groups?
Coenzymes are loosely bound organic molecules that aid enzyme function, while prosthetic groups are tightly bound non-protein molecules essential for enzyme activity.
Coenzymes are proteins that enhance enzyme activity, while prosthetic groups are lipids that inhibit enzyme activity.
Prosthetic groups are loosely bound inorganic molecules that aid enzyme function, while coenzymes are tightly bound protein molecules essential for enzyme activity.
Enzymes, coenzymes, and prosthetic groups are all types of proteins that catalyze biological reactions.
What is the term for a non-protein organic molecule that is tightly bound to an enzyme and essential for its catalytic activity?
Cofactor
Coenzyme
Prosthetic group
Activator
Which statement regarding coenzyme is incorrect?
They are organic molecules.
They are not consumed during the reaction.
They are essential for the activity of some enzymes.
They are tightly bound to the enzyme.
Enzyme often have additional parts in their structures that are made up of molecules other than proteins. When this additional chemical part is an organic molecule, it is called
Cofactor
Coenzyme
Substrate
Both (a) and (b)
An organic substance bound to an enzyme and essential for its activity, is called
Coenzyme
Holoenzyme
Apoenzyme
Isoenzyme
The substance, which is metal ion essential for the normal functioning of enzyme is called
Cofactor
Coenzyme
Holoenzyme
None of these
The tightly bound non-proteinaceous organic compound in enzyme, is
Coenzyme
Prosthetic group
Cofactor
Apoenzyme
The enzyme part, which combines with non-protein part to form a functional enzyme, is known as
Coenzyme
Holoenzyme
Apoenzyme
Prosthetic group
