In a metabolic pathway, both __________ help to keep reaction rates within normal ranges by either speeding them up or slowing them down.
A) coenzymes and cofactors
B) ligand and protein interactions
C) feedforward activation and feedback inhibition
D) affinity and substrate concentration
E) lock -in -key and induced -fit models

Question

Quizplus · Accepted Answer

Feedforward activation and feedback inhibition are regulatory mechanisms in metabolic pathways that adjust the speed of reactions to maintain homeostasis. Feedforward activation speeds up reactions further down a pathway in anticipation of increased demand, while feedback inhibition slows down reactions when the product of a pathway accumulates to sufficient levels, preventing overproduction.
