Why is ATP important in cellular processes?

• A. It functions as a catalyst in biochemical reactions.
• B. It serves as the primary energy currency of the cell.
• C. It acts as a structural component of cell membranes.
• D. It is a primary component of genetic material.

Answer: (B)

Verified step by step guidance

1. Understand the role of ATP (adenosine triphosphate) in cellular processes. ATP is a molecule that carries energy within cells.
2. Recognize that ATP is not a catalyst. Catalysts are substances that increase the rate of a chemical reaction without being consumed, whereas ATP is consumed to provide energy.
3. Identify that ATP is not a structural component of cell membranes. Cell membranes are primarily composed of lipids and proteins.
4. Clarify that ATP is not a component of genetic material. Genetic material is primarily composed of DNA and RNA.
5. Conclude that ATP serves as the primary energy currency of the cell, providing energy for various cellular activities such as muscle contraction, nerve impulse propagation, and chemical synthesis.
