| electron microscopy |
a form of microscopy in which a beam of electrons deflected by electromagnets can magnify a specimen up to 400, 000 times its original size.

| electron microscopy |
The technique used to produce an enlarged image of a tiny object that utilizes an electron microscope, an instrument that uses a beam of electrons focused by an electron lens. This type of microscopy is necessary when items or features are too small to be imaged by light. In this case, the image is created by the bending/reflection of an electron beam rather than a light beam. enzyme Protein produced by living cells that catalyze the biochemical processes necessary to sustain life.

| electron |
An electron is a negatively charged particle found circling or orbiting an atomic nucleus. An electron, like a proton is a charged particle, although opposite in sign, but unlike a proton, an electron has negligible atomic mass. Electrons contribute no atomic mass units to the total atomic weight of an atom.
