Spencer Ballantyne QUESTIONS When we say that something gives us ?energy,? what does that mean? What is a biological definition of energy? When people say that things, ?give you energy?, they can be referring to the affects other molecules like stimulants and amino acids can have on your body. Truly, they don?t provide any energy for your body, but they can raise you metabolic rate, thereby causing you to metabolize what is already stored in your body. Also, they may stimulate adrenaline production. Biologically, energy is the capacity to produce work or change. Energy is stored in your body in molecules, like carbohydrates and lipids. These carbohydrates can take the form of sugars, and the energy is transferred to your body when you eat them.
