Key” enzymes probably help to determine the balance between alternative pathways, but in general they contribute no more to the rate of a particular pathway than any other enzyme in that pathway. The third type of mechanism depends on transport rates. If nutrients and metabolites are supplied more rapidly, the rate of each metabolic pathway that uses them will increase. Slower supply rates mean slower metabolism. Not much research has been done on this aspect of cellular homeostasis, so details are lacking.

A molecule of RNA is hundreds of times longer than a protein. A mitochondrion is three or four times longer still, and a great deal fatter than an RNA molecule. Cargoes of such widely different sizes are unlikely to be moved efficiently by a single mode of transport. Therefore, the cell has a variety of transport mechanisms. The main ingredient of a cell is water. e. 1015) water molecules. Picture a small lake fed by fast-flowing streams and drained by a large river; the level of water in the lake remains practically constant, and underwater currents flow, but no individual water molecule stays in the lake for long.

A cell that manufactures a hormone must build and maintain the requisite manufacturing and secreting equipment, so the relevant anabolic pathways are active as well. A cell that takes in more nutrients than it needs for its immediate catabolic and anabolic activities converts the excess nutrient into food reserves. Let us pause to reflect on the sizes of nutrient molecules – the products of food digestion such as glucose - and other molecules involved in metabolism. Recall the "grain of salt" image of a protein molecule in a cell (chapter 3).
