Detailed explanation-1: -Energy Metabolism and ATP Synthesis in Human Cells In most animal cells, adenosine triphosphate (ATP), a compound with high potential energy, works as the main carrier of chemical energy. In general, the energy to synthesize ATP molecules must be obtained from rather complex fuel molecules.

Detailed explanation-2: -Chemical energy stored within organic molecules such as sugars and fats is transferred and transformed through a series of cellular chemical reactions into energy within molecules of ATP. Energy in ATP molecules is easily accessible to do work.

Detailed explanation-3: -metabolism, the sum of the chemical reactions that take place within each cell of a living organism and that provide energy for vital processes and for synthesizing new organic material.

Detailed explanation-4: -Metabolism (pronounced: meh-TAB-uh-liz-um) is the chemical reactions in the body’s cells that change food into energy. Our bodies need this energy to do everything from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism.
