This is an MCQ-based quiz on the topic of Enzymes - Structure, Classification, and Function.
This includes Explanation, Structure, Classification, Examples, Action, Mechanism, Interactions, Factors, Functions of Enzymes, and many more.
The nature of an enzyme is
What is the count of genes that determine the synthesis of one enzyme?
This enzyme was first isolated and purified in the form of crystals
A __________is a biocatalyst that increases the rate of the reaction without being changed.
Enzyme increases the rate of reaction by lowering the activation energy.
What is the nature of an enzyme?
What is an apoenzyme?
Name the coenzyme of riboflavin (B2)?
Enzyme-driven metabolic pathways can be made more efficient by ________.
Grouping enzymes into multienzyme free-floating complexes
Concentrating enzymes with specific cellular compartments
Fixing enzymes into membranes so they are adjacent to each other
All of these
Which statement about enzymes is true ?
Enzymes accelerate reactions by lowering the activation energy
Enzymes are proteins whose three-dimensional form is key to their function
Enzymes do not alter the overall change in free energy for a reaction
All of these
With regards to enzyme action, this statement is incorrect
Malonate is a competitive inhibitor of succinic dehydrogenase
The substrate binds with the enzyme at its active site
The non-competitve inhibitor binds the enzyme at a site distinct from that binding the substrate
Addition of a lot of succinates does not reverse the inhibition of succinic dehydrogenase by malonate
In alcoholism, this enzyme is elevated
Acid phosphatase
Hepatitis
Serum glutamate pyruvate transaminase
Glutamyl transpeptidase
