Question

what is the structural importance of the cell membrane to the cell and explain in detail the physiological importance and function in the cell.

Answer 1

Cell membrane is made up of phospholipids which are amphipathic in nature and forms bilayer and proteins which are of two types- integral and peripheral proteins. Cell membrane provides shape to the cell and do not allow the direct contact of the cell with the environment. It acts as a semipermeable membrane which only it allows the movement of selective molecules.

Cell membrane possess channels which allow the movement of ions, solutes through it across the cell to maintain the ion and solute concentration balance in the cell. It also possess receptors to which hormones bind and carry out signal transduction pathways leading to different functiona of the enzymes present within the cells.
