The protein is known as Uncoupling protein 1 (UCP1) that is present in inner mitochondrial membrane of brown adipose cells of mammals and other organisms undergoing hibernation.
Function:
The protein allows the organisms to produce metabolic heat that helps in the organism’s regulation of body temperature.
This protein can also serve as a source of carbon for the production of carbohydrates when organism faces the period of prolonged fasting and thus help the organism to survive.
The protein also helps in the movement of protons into the mitochondrial matrix that ultimately activate the electron transport chain and releases more and more heat for body’s maintenance.
<span>I think the correct answer is no. The sugars in the apple juice do not need to be broken down before used as an energy source. The sugar in the said drink are mostly fructose which can be metabolized by the body for use. Hope this answers the question.</span>
B is wrong because mitochondria would likely absorb the stain even if it was dead.(And most cells that have been treated are dead anyway). C and D are just throwaway answers, you usually want to avoid the word "always" when drawing conclusions.
