permeability of membranes: others appear to control the synthesis of certain enzymes. Evidently some hormones also control the activity of certain genes.

1. The cell is the site of a constant, complex, and orderly set of chemical changes collectively called metabolism. Metabolism is associated with a release of heat. The heat released is the same as that obtained if the same chemical change is brought about outside the living organism. This confirms the fact that the laws of thermodynamics apply to living systems just as they apply to the inanimate world. The pattern of chemical change in a living cell, however, is distinctive and different from anything encountered in nonliving systems. This difference does not mean that any chemical laws are invalidated. It instead reflects the extraordinary complexity of the interrelations of cellular reactions.

2. Hormones, which may be regarded as regulators of metabolism, are investigated at three levels, to determine their physiological effects, their chemical structure, and the chemical mechanisms whereby they operate. The study of the physiological effects of hormones is properly regarded as the province of the physiologist. Such investigations obviously had to precede the more analytical chemical studies.

3. The chemical structures of thyroxine and adrenaline are known. The chemistry of the sex and adrenal hormones, which are steroids, has also been thoroughly investigated. The hormones of the pancreas - insulin and glucagon - and the hormones of the hypophysis are peptides. The structures of most of these hormones have been determined. The chemical structures of the

plant hormones, auxin and gibberellic acid, which act as growthcontrolling agents in plants, are also known.

4. The first and second phases of the hormone problem thus have been well, though not completely. explored, but the third phase is still in its infancy. It seems likely that different hormones exert their effects in different ways. Some may act by affecting the permeability of membranes: others appear to control the synthesis of certain enzymes. Evidently some hormones also control the activity of certain genes

Определите, является ли утверждение: The sex hormones of the male follow a much simplier pattern than do those of the female.
