Read all the parts of this question before answering. Thermogenesis is a metabolic process used to generate heat in many homeothermic/endothermic/warm-blooded animals and a few species of plants. Thermogenesis involves an uncoupling protein that allows protons to flow from the intermembrane space back into the mitochondrial matrix. a. What two processes – which are normally energetically coupled – become uncoupled by the action of uncoupling proteins? b. What kind of a protein allows ions such as H+ to diffuse through a membrane?
