The molecule used by most of the animals for long-term energy storage is:
Correct answer: C. Fat
- A. Glycogen
- B. Starch
- C. Fat
- D. Cholesterol
Explanation
Fat, or adipose tissue, is the molecule used by most animals for long-term energy storage. It is composed of triglycerides, which consist of three fatty acid molecules attached to a glycerol molecule. When energy is needed, fat stores can be broken down through a process called lipolysis, releasing fatty acids that can be used as an energy source.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
