In some metabolic pathways, the regulatory enzyme is specifically inhibited by the end product of the pathway, which accumulates when the amount of this product exceeds the cell's needs. By inhibiting the regulatory enzyme (the first enzyme in the sequence), all subsequent enzymes operate at reduced rates because their substrates become depleted. A E1 B E2 C E3 D E4 P Feedback inhibition This type of regulation is called... A. End product stimulation.. B. Positive feedback. C. Negative feedback inhibition D. Positive feedback inhibition.
