Energy fuels your body's internal functions, repairs, builds and maintains cells and body tissues, and supports the external activities that enable you to interact with the physical world. Animals need to absorb all of the glucose in their guts, so when the concentration of glucose in the intestine is lower than that in the intestinal cells, the glucose must move through a process called active transport, which requires energy from respiration. Active transport requires energy as it is working against a concentration gradient and needs energy to rotate the protein transporting the solute.
