B)UCP-1;muscle
C)thermogenin;brown adipose

Question

Quizplus · Accepted Answer

Nonshivering thermogenesis utilizes the protein channel thermogenin, which is present in high levels inside the mitochondria of brown adipose tissue. Therefore, the best choice is C, thermogenin in brown adipose tissue. UCP-1, on the other hand, is another name for thermogenin, but it is not present in high levels in muscle or white adipose tissue. UCP-2 is not involved in nonshivering thermogenesis.
