Hello students, in this question they have asked to indicate whether the given statements are true or false.
00:06
The first statement given is all ion channels are highly ion selective and an ion channel always only allows one type of ion to pass through.
00:19
This statement is true because ion channels are specialized protons that form pores in cell membranes which allows specific ions to pass through.
00:43
Different ion channels are selective for different ions such as sodium, potassium, calcium and chloride.
00:51
So an ion channel typically allows only one type of ion to pass through.
00:57
Therefore this statement is true.
01:00
B .s.
01:01
Transport of ions through ion channels is classified as passive transport.
01:06
This statement is also true because passive transport refers to movement of ions or molecules across a cell membrane without the need for energy input.
01:19
Ion channels facilitate passive transport of ions by allowing them to move down their concentration gradient from an area of high concentration to an area of lower concentration.
01:47
Hence this statement is also true.
01:50
Option c is nicotinic acetylcholine receptors are ion channel linked receptors.
01:58
This statement is false...
