How does transportation of substances take place through plasma membrane?
➸The plasma membrane or cell membrane is a lipid bilayer membrane in which proteins are embedded that separates the cytoplasm of the cell from the extracellular spaces.
➸It is selectively permeable that regulates the transportation of molecules
➸The transportation of molecules across the membrane can be active or passive.
1) Active transportation-
is the movement of molecules (ions, glucose and amino acids) across the membrane against the concentration gradient.
➸It requires cellular energy.
➸The protein molecules embedded within the membrane act as channels through which molecules can pass.
➸These proteins are called carriers i.e, the molecule attaches to the carrier protein which then transports that molecule into the cell.
2) Passive transportation-
is the movement of molecular substances across cell membranes along the concentration gradient without any energy.
They are of three types:-
a) Diffusion-
➸is the movement of molecules from the area highly concentrated to an area where the molecules are less concentrated.
b) Osmosis-
➸ is the diffusion of water molecules.
c) Filtration-
➸is the movement of water and solute molecules across the cell membrane due to hydrostatic pressure generated by the cardiovascular system.
