Cell Membranes & Transportation – සෛල පටල හරහා පරිවහනය සිදුවන ආකාර

In cellular biology, membrane transport refers to the collection of mechanisms that regulate the passage of solutes such as ions and small molecules through biological membranes, which are lipid bilayers that contain proteins embedded in them. The regulation of passage through the membrane is due to selective membrane permeability – a characteristic of biological membranes which allows them to separate substances of distinct chemical nature. In other words, they can be permeable to certain substances but not to others.

Transport types
-Passive diffusion
-Active and co-transport
Secondary active transporter proteins
-Pumps
Membrane selectivity
-Electrolyte selectivity
-Non-electrolyte selectivity

This video will introduce you about all kinds of transportation techniques via cell membranes. This video clearly explains, make it simple to understand.
