Which tissue is described as providing extra fuel for the body?

• A. Dermis
• B. Subcutaneous tissue
• C. Epidermis
• D. Muscle

Answer: (B)

Adipose tissue stores energy in the form of fat, serving as an extra fuel reserve for the body. This tissue sits in the subcutaneous layer just beneath the skin, where adipocytes hold triglycerides. When energy is needed, hormones trigger lipolysis to release fatty acids that cells can use for fuel. Besides providing energy, subcutaneous fat also offers insulation and cushioning for organs. The other tissues have different primary roles: epidermis is the outer protective skin layer, dermis contains structural and sensory components but doesn’t store fuel, and muscle is for contraction and movement, using energy rather than primarily storing it.
