Hello.
00:02
So here in this question, few statements are given and we have to find that which statement is true that is for passive transport across a biological membrane.
00:13
So let's see what are the statements given.
00:17
Here the statement 1 or a is saying that passive transport, this is dependent on both solute electrochemical gradient and atp.
00:27
Statement 2 is saying that passive transport, this is a reverse.
00:31
And statement c is saying that posit transport is reversible and here the statement d is saying that posit transport can be provided by channels not by carrier transporters and here the e statement e is saying that positive transport is driven by a solute electrochemical gradient so let's see this statement one by one and find out which one is the true or which state how many statements are true here so here starting with the statement of one that is a here they are passive transport this is dependent on solute electrochemical gradient yes it is dependent on solid electrochemical gradient what we understand uh from the solute electrochemical gradient uh this is actually the driving force uh that determine the passive transport of solute across a member but it is also saying it is dependent on atp so what we know for passive transport there is no use of any energy any type of energy atp is energy in other words simple words we can say it's energy but in passive transport there is no use of any energy so here statement a is not coming to the statement b that passive transport here this is irreversible.
02:01
So yes, the statement saying that it is irreversible means we can understand here a transporter can provide transport only in one direction.
02:14
Here one direction.
02:16
So this statement is also false because passive transport is reversible.
02:25
So there this is false and here c statement that this is reversible.
02:30
Reversible means here a transporter can provide transport in both the direction.
02:34
We can see this in a diffusion, which is a diffusion, which is a type of passive transport.
02:41
So here this process is reversible.
02:44
Means we can see it transport in both the directions.
02:48
So here statements see this is true.
02:52
So here we can write as the true statements.
02:58
Statements are the first one is here it's c.
03:04
And now coming to the statement d, it's saying that passive transport, this can be provided by channels, but not by carrier transporter...
