Detailed explanation-1: -If you were preparing for hibernation, however, or a long distance migration, you would want to use fat for storage because fat stores, per gram, twice as much energy as carbs or protein, and can therefore last the distance.
Detailed explanation-2: -Fats are the primary long-term energy storage molecules of the body. Fats are very compact and light weight, so they are an efficient way to store excess energy. A fat is made up of a glycerol, which is attached to 1 to 3 fatty acid chains.
Detailed explanation-3: -The bear’s metabolism is very low during hibernation, it does not require much energy to maintain its body, thus glycogen stores are quickly filled and the excess nutrients get converted to triglycerides which are stored for the long term in fat cells.
Detailed explanation-4: -Lipids contain amino acids necessary for protein synthesis. Answer: B.) Lipids store energy and vitamins that animals need.
