Which of these groups plays a major role in energy transfer in biological systems?

• A. Nucleic Acids
• B. Lipids
• C. ATP (Adenosine Triphosphate)
• D. Carbohydrates

Answer: (C)

Verified step by step guidance

1. Identify the primary function of each group mentioned: Nucleic Acids, Lipids, ATP, and Carbohydrates.
2. Understand that Nucleic Acids are primarily involved in the storage and transmission of genetic information.
3. Recognize that Lipids are mainly involved in long-term energy storage and forming cell membranes.
4. Learn that ATP (Adenosine Triphosphate) is the main energy currency of the cell, used for energy transfer in various biological processes.
5. Acknowledge that Carbohydrates are a primary source of energy, but ATP is directly involved in energy transfer within cells.
