👉 Interinhibition is a biological phenomenon in which an enzyme's activity is inhibited by another enzyme. This can occur when two or more enzymes are bound to each other and one of them has an altered activity, leading to decreased availability of the other enzyme for its own activity. In summary, interinhibition refers to the inhibition of an enzyme's activity due to the presence of a second enzyme that competes with it for substrate binding. This can occur in complex reactions involving multiple enzymes or within single enzyme
