00:01 Hello.

00:02 As per the question, there are the statement given about the facilitated diffusion and we need to find out which amongst them is not true or which among them is a false one.

00:17 So facilitated diffusion is what? simply a diffusion or transport of substance to put it in a simple words.

00:26 Transport of substance across the membrane, that is a plasma membrane, via some carrier proteins.

00:39 So there are some carrier proteins or there are also called as transmembrane proteins.

00:46 Those will help the substance to cross across the membrane.

00:52 Okay.

00:53 So let's see what are the given statements about the facetabre.

00:57 Diffusion.

00:59 First statement says that it requires atp.

01:03 Now as i mentioned it is a spontaneous process where there is no requirement of atp therefore this statement is false.

01:14 Second statement let's see it says the transport protein and the transport substance means the protein that is involved in transport that is the carrier protein as i said and the substance that has to be transported are specific to each other.

01:34 This statement is true.

01:36 Not all proteins can randomly carry any substance.

01:41 There should be some specificity to carry the substance...
