Verified step by step guidance
1
Understand the primary function of carbohydrates in the human body. Carbohydrates are essential macromolecules that serve as a major source of energy.
Recognize that carbohydrates are broken down into glucose, which is used in cellular respiration to produce ATP, the energy currency of the cell.
Consider the options provided: membrane construction, structural molecules, building genetic material, and lipid storage. Evaluate each option in the context of carbohydrate function.
Membrane construction and structural molecules are primarily associated with proteins and lipids, not carbohydrates. Building genetic material involves nucleic acids, and lipid storage is related to fats.
Conclude that the main role of carbohydrates is energy storage and release, as they are metabolized to provide energy for various cellular processes.
