Detailed explanation-1: -The energy produced during respiration is used in many different ways, some examples of what it is used for are: Working your muscles. Growth and repair of cells. Building larger molecules from smaller ones i.e. proteins from amino acids.
Detailed explanation-2: -During the process of respiration, oxidation of high energy food substances takes place in the cells of the living organisms to produce energy. The energy released in the process is in the form of the chemical substance called ATP ( Adenosine Triphosphate).
Detailed explanation-3: -Muscles need energy to produce contractions (Fig. 6). The energy is derived from adenosine triphosphate (ATP) present in muscles. Muscles tend to contain only limited quantities of ATP.
