Which of the Following is NOT a Mechanism of Thermogenesis

Question

Which of the following is NOT a mechanism of thermogenesis in birds and mammals?
A)ram ventilation
B)brown fat
C)involuntary shivering
D)ATPase pump enzymes
E)voluntary muscle contraction

Accepted Answer

Ram ventilation refers to the process of extracting oxygen from water in fish and other aquatic animals, and is not a mechanism of thermogenesis in birds and mammals. The other choices - brown fat, involuntary shivering, ATPase pump enzymes, and voluntary muscle contraction - are all mechanisms that generate heat in these animals.
