Hormones kinetic principles

Kinetic principles that apply to hormone action... 

Althongh many hormones are involved in control of many biochemical and physiological processes, the kinetic principles nnderlying the mechanisms by which this is achieved are similar if not identical for each hormone. These principles are onthned nnder four separate headings. 

KINETIC PRINCIPLES THAT APPLY TO HORMONE ACTION... 

The quantity of any given solute being presented to the reabsorptive mechanisms is determined by the product of the GFR and the solute concentration in plasma. One of the features of any carrier-mediated process is its limited capacity. Binding of a substance to its transport protein follows the same principles as substrate binding to an enzyme or hormone binding to its receptor so we may appropriately liken the dynamics to Michaelis-Menten kinetics.
