Both monosaccharide and disaccharides traverse the walls of blood and lymph capillaries serious cavities freely by a simple process of diffusion. Their concentrations throughout the extracellular fluid are, therefore, uniform except as the equilibrium may be disturbed in local areas by exchanges of monosaccharide with cells. They traverse the glomerular filter with the same freedom.

Since carbohydrate are composed of units consisting of a carbon atom and a molecule of water, one molecule of oxygen will be required to oxidize a unit to CO 2 and water: C – H2 O + O2 = C O2 + H O2. The molecular respiratory quotient O2 consumed / CO 2 produced is [...]
