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?

Produce Heat

Explanation:

Thermogenin, also known as the uncoupling protein is produced by brown fat cells. It causes leads to the uncoupling of oxidative phosphorylation by allowing the transport of protons across the cell membrane and the energy is dissipated as heat.
