Unformatted text preview: wall. Feedback Inhibition Negative feedback inhibition is like a thermostat. When it is cold, the thermostat turns on a heater which produces heat. Heat causes the thermostat to turn off the heater. Heat has a negative effect on the thermostat; it feeds back to an earlier stage in the control sequence as diagrammed below. Many enzymatic pathways are regulated by feedback inhibition. As an enzyme's product accumulates, it turns off the enzyme just as heat causes a thermostat to turn off the production of heat. The end product of the pathway binds to an allosteric site on the first enzyme in the pathway and shuts down the entire sequence. Feedback inhibition occurs in most cells....
