Most of the major molecules of the cell - whether structural, like cellular equivalents of a building’s girders and beams, or mechanical, like enzymes that take apart or put together other molecules, ...Most of the major molecules of the cell - whether structural, like cellular equivalents of a building’s girders and beams, or mechanical, like enzymes that take apart or put together other molecules, are proteins. Proteins interact with a wide variety of other molecules, though any given interaction is usually quite specific. The specificity is determined in part by electrical attraction between the molecules.
