A

inner membrane of mitochondrion

19
Q

Citric Acid Cycle produces

A

2 ATP and 4 C0²

20
Q

Q

(ABIBS) stands for

A

(A)veolar Fluid
(B)asement Membrane of the
alveolar epithelium
(I)nterstitial Space
(B)asement Membrane of the capillary endothelium.
(S)imple Squamous Endothelium of the capillary

22
Q

Partial pressure of oxygen in the alveoli in the lungs =

A

104mmHg

23
Q

Partial pressure of carbon dioxide in the alveoli in the lungs =

A

40mmHg

24
Q

Describe how the Heering-Breur reflex works

A

When you inspire deeply, you stretch bronchioles and as the receptors stretch, they start sending action potentials to the medulla oblongata. If the action potentials are frequent enough, they inhibit the dorsal respiratory group. Once the dorsal group is inhibited, inspiration stops and expiration begins. (This is an example of negative-feedback)

25
Q

The more C0² in the blood plasma,

A

the lower the pH of the blood

26
Q

The level of carbon dioxide guides the chemical control of

A

ventilation

27
Q

Dalton’s law states that

A

the pressure exerted by a mixture of gases is equal to the sum of the partial pressure of each gas in the mixture.

28
Q

Using Dalton’s law, figure this problem out…

The different components of the air,
1 atmosphere of pressure is 760mmHg
Nitrogen = 74%
Oxygen = 20%
Water Vapor = 6%
Carbon Dioxide = 0.04%

What is the partial pressure of oxygen?

A

152mmHg

29
Q
