What type of tissue stores energy?

• A. Adipose tissue
• B. Epithelial tissue
• C. Muscle tissue
• D. Connective tissue

Answer: (A)

Energy storage in the body is carried out by adipose tissue. It is made up of adipocytes that store energy as triglycerides within lipid droplets. This stored fat is highly energy-dense, providing a long-term reserve that can be mobilized when needed, such as between meals or during activity. Hormones trigger lipolysis to release fatty acids into the bloodstream to fuel other tissues. Beyond storage, adipose tissue also helps insulate and cushion the body. Epithelial tissue forms coverings and barriers, muscle tissue is primarily for contraction and rapid energy use, and connective tissue is a broad category that includes many tissues; among them, adipose tissue specializes in storing energy.
