Vitamins and Coenzymes

A class of organic compounds needed in the human body for normal activities is known as vitamins. They are characterized into two parts depending upon their solubility in water. They can act as coenzymes, cofactors, or prosthetic groups for enzymes.

Question

Classify each phrase as describing a competitive inhibitor, uncompetitive inhibitor, or mixed (mixed noncompetitive) inhibitor.
Note that Km refers to apparent Km ·
Competitive inhibitor
structurally similar to substrate
when present, Km of enzyme will decrease
prevents substrate from binding enzyme
Uncompetitive inhibitor
when present, Vmax of enzyme is unaffected
binds enzyme-substrate complex only
Answer Bank
Mixed inhibitor
binds either enzyme or enzyme-
substrate complex
when present, Km of enzyme will either
increase or decrease
