Q

what would happen to the process of CR if an inhibitor were introduced? how would this affect human health and survival

A

this would result in uncoupling and can be detremental to ones health. a case being “luft syndrome” where a woman was not producing ATP due to uncoupling and her body temperature spiked due to the thermal heat energy being produced
