Brown fat cells produce a protein called thermogenin in their mitochondrial inner membrane. Thermogenin is a channel for facilitated transport of protons across the membrane. What will occur in the brown fat cells when they produce thermogenin?

Question

Quizplus · Accepted Answer

When brown fat cells produce thermogenin, it allows for the facilitated transport of protons across the mitochondrial inner membrane. The movement of protons generates a proton gradient, which leads to an increase in heat generation (thermogenesis) and a decrease in ATP synthesis. This is because the energy produced from the electron transport chain is used to generate heat instead of ATP synthesis. Therefore, choice C is the best answer.
