Km remains the same and Vmax is reduced. What is the type of Enzyme inhibition?
Noncompetitive Inhibition
A type of inhibition in which the inhibitor bind to a site distinct from the substrate binding site. Two different types are:

Reversible Noncompetitive Inhibition (Only few Noncompetitive inhibition are reversible)
Irreversible Noncompetitive Inhibition (Most of Noncompetitive are irreversible).
Competitive Inhibition
Noncompetitive Inhibition
Uncompetitive inhibition
Suicide Inhibition
