00:01 Okay, this question says, you have first the following formula.

00:04 This carbon dioxide reacts with water and by means of the enzyme carbonic alkanes you are going to produce carbonic acid, okay? and by means of the same enzyme you are going to produce hydrogen ions and bicarbonate.

00:17 This is the reaction that you have here.

00:19 And it says, review this formula and discuss the mechanisms involving the forward and reverse components of the reaction by answering the following.

00:28 It says, when carbon dioxide and water combine to form carbonic acid, discuss the respiratory mechanisms involved to regulate the levels of carbon dioxide.

00:36 So for example, when you hyperventilate, it means when you increase the work of breathing or you increase your respiratory rate, what is going to happen? well, when you increase your ventilatory rate, what is going to happen is that you're going to increase the excretion of carbon dioxide.

00:58 You're going to excrete more carbon dioxide because you are hyperventilating.

01:01 So if you increase the excretion of carbon dioxide in your body, you're going to have decreased amounts of carbon dioxide.

01:08 So in this case, what is going to happen? you're going to have less production of hydrogen ions.

01:14 And if you have less production of hydrogen ions, what is going to happen is that the ph is going to increase.

01:21 So this is what is going to happen if you hyperventilate.

01:24 And the opposite is going to happen when you hypoventilate.

01:26 It means if your respiratory rate is decreased.

01:29 If your respiratory rate is decreased, you're going to retain more carbon dioxide.

01:34 And hence, you're going to produce more hydrogen ions.

01:36 And hence, you're going to decrease the ph and you're going to have acidosis.

01:42 Then it says, explain why exaggerated respiration and misincreased ventilation help to decrease the levels of hydrogen ions.

01:48 And as i mentioned, because when you hyperventilate, you're going to excrete more carbon dioxide and you're going to have less carbon dioxide...
