Which of the following is a primary function of adipose connective tissue?

• A. Transporting oxygen
• B. Secreting hormones
• C. Producing movement
• D. Energy storage

Answer: (D)

Verified step by step guidance

1. Step 1: Begin by identifying the type of tissue mentioned in the problem—adipose connective tissue. Adipose tissue is a specialized type of connective tissue primarily composed of fat cells (adipocytes).
2. Step 2: Understand the primary functions of adipose tissue. These include energy storage, insulation, cushioning of organs, and serving as an endocrine organ by secreting hormones like leptin.
3. Step 3: Compare the listed options with the known functions of adipose tissue. For example, transporting oxygen is a function of blood, secreting hormones is a secondary function of adipose tissue, and producing movement is a function of muscle tissue.
4. Step 4: Focus on the correct answer, 'Energy storage,' which is the primary function of adipose tissue. Adipocytes store energy in the form of triglycerides, which can be broken down into fatty acids and glycerol when the body needs energy.
5. Step 5: Conclude by emphasizing that while adipose tissue has secondary roles, its primary function is energy storage, making it essential for maintaining energy balance in the body.
