PLASMA MEMBRANE Cont.
FUNCTIONS
Centre of cellular respiration and oxidative phosphorylation in
prokaryotes
It act as permeability barrier and regulates the inflow and outflow of
materials
It helps to keeps up a constant physiological condition inside the cell
Selective transport of useful substances into the cell by active and
passive mechanisms and endocytosis
Elimination of wastes and release of secretory products by
exocytosis
, PLASMA MEMBRANE Cont.
Transmission of impulses in excitable cells ( Nerve cells & Muscle
Recognition and binding of some hormones (Insulin)
Recognition of foreign cells ( Recognition of bacteria)
Chemoreception in bacteria
Signal transduction – Response to external signals by a proces
signal transduction which involves binding of membrane recep
specific signal molecules called ligands.
