Question

What are different types transport of components across cell membrane?​

Answer 1

Answer:

heres ur answer

Explanation:

There are two types of transport:-

   Passive Transport:

   This type of transport does not require any kind energy for it to be transported and is independent on the permeability of the cell membrane.

   This is divided into three types:

   Diffusion: Movement of particles from a region of higher concentration to a region of lower concentration.

   Osmosis: Movement of solvent particles from a less concentrated solution into a more concentrated one through a semi-permeable membrane.

   Facilitated Diffusion: It is the spontaneous transport of molecules or ions across a cell's membrane through a specific trans-membrane integral proteins (that are embedded to the lipid bilayer).

   Active Transport:

   This type of transport requires the use of energy in the form of Adenosine Triphosphate (ATP), which is produced by cell organelle called mitochondria.

   This is also divided into three types:

   Sodium-Potassium Pump: This usually helps in the transport of ions like sodium and potassium. It pumps three sodium ions out of the cell for every two potassium ions that is pumped in.The carrier is usually the ATP-ase.

   Exocytosis: The act of pushing the materials outside the cell membrane through the help of secretory vesicles.

   Endocytosis: The act of swallowing/engulfing the particles through the cell membrane.

Answer 2

Passive Transport Passive transport is the movement of molecules across the cell membrane and does not require energy.  It is dependent on the permeability of the cell membrane.  There are three main kinds of passive transport - Diffusion, Osmosis and Facilitated Diffusion.
