In noncompetitive inhibition

• the inhibitor binds to a different part of the enzyme causing a change of shape.

• the inhibitor binds to the active site of the enzyme causing a change of shape

• the substrate bind to the active site.

• the substrate and inhibitor are the same shape.

The induced fit model of the enzyme-substrate interaction can possibly overcome competitive inhibition by

• increasing concentration of the substrate.

• decreasing concentration of the substrate.

• increasing the concentration of the enzyme.

• changing the active site.

___ are proteins that act as organic catalysts.
