Does oxygen and carbon dioxide moving from alveoli to capillaries requires energy?
It does not require energy. It move down the concentration gradient naturally.
Why does oxygen diffuse in and carbon dioxide diffuse out?
In the alveoli, oxygen diffuses into the blood that the capillaries carry due to a concentration gradient that exists there as oxygen conc is higher in the alveolar sacs than in the blood capillaries. Similarly carbon dioxide diffuses out of the blood capillaries into the alveolar sacs down the concentration gradient. The constant flow of blood is there to ensure this concentration gradient is established at all times.
Where would carbon dioxide concentration be the highest?
The carbon dioxide concentration would be the highest where the oxygen is low.

Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
Where does oxygen pass into your blood?
Oxygen diffuses into the blood in the lungs and binds to the hemoglobin since the oxygen concentration is high and the carbon dioxide concentration is low. The blood is pumped to the body. The hemoglobin releases the oxygen to the tissues because here, the concentration of oxygen is low and that of carbon dioxide is high.
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
Is Oxygen diffusion rate affected by the pressure gradient of carbon dioxide?
No According to my utas quiz :)
Why exhaling carbon dioxide can not put out a fire?
When you exhale, you are not exhaling carbon dioxide. You are exhaling air with a slightly higher-than-normal concentration of carbon dioxide and a slightly lower-than-normal concentration of oxygen. Carbon dioxide extinguishes fire by forcing oxygen away from the fuel, but the air you exhale still has more than enough oxygen to support combustion.
Does air entering the alveoli have a high level or a low level of carbon dioxide?
The alveoli have high concentrations of oxygen, especially when compared to venous blood. This concentration gradient is why oxygen diffuses across the alveolar wall into the bloodstream.
Why is the oxygen -carbon dioxide cycle important?
It regulates the carbon dioxide concentration of our atmosphere, keeping temperatures moderate.Read more: What_is_the_importance_of_carbon_dioxide_oxygen_cycle
