What gas diffuses through cell membranes so that respiration can take place?
oxygen
Where does oxygen gas come from in photosynthesis?
The splitting of water by the process of photolysis in photosystem II. There the electrons and protons are used in the process of photosynthesis but oxygen gas is a byproduct that diffuses out of the stomata into the atmosphere.
What makes the concentration of oxygen low in the alveolus?
Oxygen diffuses into the blood capillary
How do your eyes get oxygen?
Oxygen first dissolves in the tears and then diffuses throughout the cornea to keep it healthy
Which gas diffuses fastest in and out of body tissues?
Nitrogen
What gas diffuses at the same rate as nitrogen?
Oxygen
Name the gas that moves in and out of body cells?
Oxygen diffuses into cells. Carbon dioxide diffuses out.
Oxygen diffuses into the blood from the?
o2 diffuses into blood from alveoli of lungs through the respiratory membran.
Which gas diffuses faster O2 or CO2 and how much faster?
oxygen
Which gas diffuses faster SO3 or O2?
Oxygen diffuse faster.
What gas diffuses through cell membranes so that respiration can take place?
oxygen
What gas diffuses most rapidly Carbon Dioxide or methane or nitrogen or oxygen or chlorine?
carbon dioxide
Where does oxygen gas come from in photosynthesis?

What gases oxygen nitrogen helium or hydrogen which diffuses most rapidly at twenty-five degrees centigrade?
This gas is hydrogen.
How does ventilation help maintain a difference in oxygen concentration?
As it circulates, the oxygen diffuses into the blood via the alveolar wall, this then transfer the oxygen to the red blood cells, as diffusion occurs at this point, oxygen diffuses from a high concentration to a low concentration, so the oxygen diffuses into the blood whereas the CO2 diffuses into the alveoli and then out of the mouth when we expire.
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
What two body systems work together for gas transport?
RESPIRATORY system (lungs) brings oxygen-containing air into tiny air sacs called alveoli where the oxygen diffuses into the CIRCULATORY SYSTEM (blood vessels) and carbon dioxide diffuses out of the blood vessels which is then exhaled.
