In the living adult human, the esophagus is about 25 centimeters long, and most of its length is within the thorax, directly anterior to the vertebral bodies.
<h3>What is the esophagus?</h3>
The esophagus is a like-tubular structure of the digestive system that serves to transport foods during digestion.
The esophagus is composed of muscular walls that link the pharynx structure with the stomach in the digestive system.
Moreover, the vertebral bodies are thick segment (bone) structures of the skeletal system.

Answer;
-ATP; Nuceotide.
ATP is the main source of chemical energy that drives all cellular work and belongs to the class of organic molecules known as Nucleotide.
Explanation;
-ATP, adenosine triphosphate, is a high energy molecule, powers (drives) nearly all forms of cellular work. Hydrolysis of ATP releases energy by transferring its third phosphate from ATP to some other molecule in a process called phosphorylation.
-ATP is a nucleic acid. Specifically it is a nucleotide. ATP is one of four nucleic acid bases that forms the polymer RNA. In metabolism, ATP is a form of stored chemical energy.
-ATP consists of the adenine nucleotide (ribose sugar, adenine base, and phosphate group, PO4-2) plus two other phosphate groups. Energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
