2、s down the tuhules,its volume is reduced and its composition altered by the processes of tubular reabsorption(removal of water and solutes from the tubular fluid)to form the urine that enters the renal pelvis.A comparison of the composition of the plasma and an average urine specimen illustrates the
3、 magnitude of some of these changes and emphasizes the manner in which wastes are eliminated while water and important electrolytes and metabolites are conserved.Lesson 7Renal function and micturition Furthermore,the composition of the urine can be varied,and many homeostatic regulatory mechanisms m

24、ed to as“receptor”.Not only must the chemical messenger be recognized,but the combination of it with receptor must initiate the series of biochemical events that result ultimately in a biological event.Thus,the concept of receptor implies that the same molecule that has the binding or recognition si
25、te can participate normally in the initiating event in cell activation.This part of the molecule may be referred to as“effector”.In all likelihood,the same molecule contains both“recognition”and“activation”regions,which may be separate,identical,or partially overlapping.Many of the receptors for che
26、mical messengers have now been isolated and characterized.These proteins are not static components of the cell,but their numbers increase in response to various stimuli,and their properties change with changes in physiologic conditions.When a hormone or neurotransmitter is present in excess,the numb
27、er of active receptors generally decreases (down regulation),whereas in the presence of a deficiency of the chemical messenger,there is an increase in the number of active receptors (up regulation).There are also cross stimulation effects,one substance affecting the number or the affinity of recepto
28、r for other substances,or both.Receptor-mediated endocytosis is responsible for down regulation in some instances.As noted above,ligands bind to their receptors in the membrane and the ligand-recepor complexes move laterally in the membrane to coated pits,where they are taken into the cell by endocy
29、tosis(internalization).This decreases the number of receptors in the membrane.Some receptors appear to be recycled after internalization,whereas others are only replaced by de novo synthesis in the cell.Internalization is too slow a process to explain the rapid actions of hormones,but it has been ar
30、gued that some of the slower actions of hormones may be due to the action of internalized hormone within the cell.Limiting scope of work(1)This problem is concerned with the study ofThe problem of deals largely with the determination of The problem they have advanced bears on the elucidation ofThe p
