What is the function of adipocytes?

• A. To generate new red blood cells
• B. To store energy as fat
• C. To synthesize bile
• D. To transport oxygen

Answer: (B)

Adipocytes specialize in storing energy as fat. They pack fatty acids and glycerol into triglycerides inside lipid droplets when there's excess energy and can mobilize that fat later to supply energy to other tissues by breaking triglycerides back down into fatty acids and glycerol. They also contribute to metabolism through signaling molecules, but their main function is energy storage as fat. Gist for the other options: red blood cells are made in bone marrow to carry oxygen, bile is synthesized by the liver, and oxygen transport is the job of red blood cells, not adipocytes.
