Feedback inhibition definition microbiology

Webinhibition: [noun] the act of inhibiting : the state of being inhibited. something that forbids, debars, or restricts. WebMar 6, 2024 · Feedback inhibition always operates by allosterism and further, provides important and efficient control of an entire pathway. By inhibiting an early enzyme in a pathway, the flow of materials (and ATP hydrolysis required for their processing) for the entire pathway is stopped or reduced, assuming there are not alternate supply methods.
