Which molecule is the primary carrier of chemical energy in cells?

Explanation:
The main concept is that ATP acts as the cell’s energy currency. Its three phosphate groups store energy in the bonds between them, especially the bond linking the last phosphate. When a cell needs energy for processes like muscle movement, transport across membranes, or building molecules, ATP donates that terminal phosphate, forming ADP and inorganic phosphate and releasing usable energy. This ready-to-use energy makes ATP the primary carrier of chemical energy in cells. Glucose is a fuel that must be broken down to release energy, which then fuels ATP production. ADP and AMP are lower-energy forms; ATP is regenerated from ADP (and Pi) or from AMP through cellular respiration and other pathways.
