Brown fat cells produce a protein called Thermogenin

Q. 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?

A) Both ATP synthesis and heat generation will be increased.

B) Both ATP synthesis and heat generation will be decreased.

C) ATP synthesis will be increased and heat generation will be decreased.

D) ATP synthesis will be decreased and heat generation will be increased.

E) Both ATP synthesis and heat generation will remain the same.

 

Answer:  D (ATP synthesis will be decreased and heat generation will be increased). To study more about thermogenin function in brown fat cells, click here.
