So, we will first identify and understand the process of diffusion in particular.
00:06
So, when we speak about diffusion, what we do understand that.
00:10
This occurs or involves the movement of the molecules written as mov representing movement and mol representing molecules or ions in particular from a region of higher concentration represented as h to a region of low concentration.
00:30
Represented as l.
00:32
It may or may not occur across the semi permeable membrane written as sm spm.
00:40
So this is about the diffusion.
00:43
So in diffusion there is no change involved.
00:46
So there is particularly no change that occurs or is involved as it is along the concentration gradient.
00:57
So written as c -o -n -c -g.
00:59
So along the concentration gradient but in active transport written as it movement of molecules occurs against the concentration gradient written as cg that is from the concentration of lower concentration to the higher concentration in particular now when we speak about the active transport in particular what we do understand from the process of active transport is that that the active transport energy is vital for movement.
01:37
So there is requirement of energy for the movement.
01:41
In this case, protein molecule is been used and this protein molecule functions as a molecular pump in particular.
01:54
So this facilitates as molecular pump which enables the cell to accumulate glucose or ions written as g or i against the concentration gradient again written as cg.
02:10
Here the metabolic energy required is adenosine triphosphate or atp...
