Okay, this question here says as blood flows through systemic capillaries, let's go for each of the options.
00:07
Option a says by carbon it is converted to carbon dioxide.
00:10
And this is false because remember that in the systemic capillaries there is some type of exchange of gases where oxygen from the blood is going to go into the tissues and carbon dioxide from the tissues is going to go to the blood.
00:24
So the blood is going to become deoxygenated and carbon dioxide is going to be transported towards the lungs.
00:29
And one way of transport of this carbon dioxide is as bicarbonate.
00:33
Okay, so carbon dioxide is particularly going to convert into bicarbonate.
00:37
Option b says hydrogen ions bind to hemoglobin.
00:42
And this is also false because, or sorry, actually this option here is also true, okay? because in this case, this is one transport of carbon dioxide, okay? but there is another transport of carbon dioxide.
00:57
It is dissolved in the blood.
00:58
This is the second.
00:59
And the third one is as carbamino hemoglobin.
01:02
It means hydrogen ions bound to hemoglobin.
01:05
So this is actually true...
