Final answer:
An energy-bearing molecule composed of carbon, hydrogen, nitrogen, oxygen, and phosphorus atoms is adenosine triphosphate (ATP).
Step-by-step explanation:
An energy-bearing molecule composed of carbon, hydrogen, nitrogen, oxygen, and phosphorus atoms is adenosine triphosphate (ATP). ATP is the main source of energy in cells and is used for various cellular processes, such as muscle contraction, active transport, and synthesis of macromolecules. It consists of a nucleotide with three phosphate groups.
