Using hydrogen in his experiments Bohr showed that an electron spins around the atom nuclei at a specific/discrete radii (orbital levels). Electrons at every orbital level spin at a discrete angular momentum and energy. When the electron moves one orbital level down, it releases a photon of energy specific to the jump (that is, of a particular spectrum that is unique to the atom). When the electron goes up an orbital level, energy (of a specific spectrum) is absorbed. This emission and absorption spectrum varies across atoms and is calculated as (delta)E = hf where;
E = energy
h = Planck's constant
f = frequency

If a person blood sugar is 120 mg/mL that person already have diabetes mellitus. Diabetes mellitus is a medical condition in which the level of glucose in the blood is very high because the glucose were not able to enter the body cells. The condition is usually cause by absence or inadequate level of insulin in the body.
