Brown fat found in small hibernating animals and infants has a protein that acts like DNP We would therefore expect brown fat to heat production because Decrease it is more dense that regular white fat This limits O2 diffusion thereby decreasing the rate of aerobic metabolism and therefore heat generation Decrease it contains more mitochondria This increases the efficiency with which glucose catabolism is coupled to ATP Synthesis and therefore less of the chemical energy of catabolism is lost as heat Increase it is more dense than regular white fat so it is a better temperature insulator By maintaining the temperature of the organism closer to the optimal temperature for enzymes metabolism and therefore heat generation is maintained Increase it contains a protein that forms a pore in the inner mitochondrial membrane This allows H to diffuse down its gradient without the energy being captured and coupled to ATP Synthesis The energy is lost as heat
