The cell membrane regulates substrate intake, waste excretion, mineral balance, gas exchange, and reception and translation of chemical and physical stimuli. The membrane is a precisely fashioned supramolecular assembly of phospholipids, simple proteins, glycoproteins, and lipoproteins. Enzymes and transport proteins form part of its structure. Specific molecules at the surface serve as receptors for a variety of hormones, especially those with peptide- or amino acid-derivative structure. The interaction of a hormone with its membrane receptor may modify rates and direction of substrate transport and give rise to "secondary messages" that modulate other cell functions.
Present concepts will be reviewed, with
