Living organisms can be thought of as heat machines and metabolism as the inner workings of the machine. The metabolism converts energy from the combustion of food into useful work (mostly chemical work that makes new material for the living cell) so efficiency (useful work rather than wasted heat) can be maintained. Human metabolism has two goals. First, we obviously must maintain energy production, the useful part of which is usually measured by the availability of biological intermediates that can drive life processes. Second, we must maintain more or less constant levels of blood glucose.Read More
