Lipids have great functional significance in the body. What are the main functions of the lipids?

Correct answer: D. All of these

  • A. Energy storage and source
  • B. Mechanical protection and insulation
  • C. Structural component of cell membranes
  • D. All of these

Explanation

The correct answer is all of these. Lipids are versatile biological molecules that perform several key functions in the body. They are a major source of energy, stored in adipose tissues and used when energy demands exceed intake. Lipids also provide mechanical protection, cushion organs, and insulate the body. Additionally, they are fundamental components of cell membranes, contributing to membrane structure and function. Options A, B, and C each highlight one of these roles but do not cover the complete range of lipid functions.
