Which common object contains phosphorus and is linked to the energy carrier molecule ATP?

• A. Matches; ATP
• B. Water; ATP
• C. Charcoal; ATP
• D. Salt; ATP

Answer: (A)

Phosphorus is essential for ATP, the cell’s energy currency, because ATP stores energy in the bonds between its phosphate groups. The energy released when ATP is converted to ADP comes from breaking those phosphate bonds. A familiar object that contains phosphorus is matches, whose heads historically used phosphorus compounds. That connection makes matches the best example of a common item linked to ATP through phosphorus. In contrast, water, charcoal, and salt don’t involve phosphorus in a way that ties to the phosphate bonds in ATP, so they don’t illustrate this relationship.
