A plot of velocity vs substrate concentration for allosteric

A plot of velocity vs. substrate concentration for allosteric enzymes level off because

substrate levels are low resulting in a slow reaction velocity.

substrate levels are high leading to slow reaction velocity

the active sites are saturated resulting in maximal velocity.

the active sites are nearly empty, which limits inhibition and results in maximal velocity.

Solution

The active sites are saturated resulting in maximal velocity.... allosteric enzymes dont follow michaelIs-menten kinetics they follow a sigmoid curve, but the reason for level off is same which is active site saturation.

Hope it helps
