Answer:

B. It is the primary molecule in which cells store and use energy.

Explanation:

ATP (adenosine triphosphate) is an energy-carrying molecule found in the cells of all living organisms. It provides the energy necessary for many functions, such as muscle contraction, nerve impulse propagation, chemical processes, etc. It consists of three main structures:

  • the nitrogenous base called adenine
  • the sugar called ribose
  • a chain of three phosphate groups bound to ribose. This phosphate chain is the source of energy the cell uses.
