Gases diffuse down a ____ gradient.
A) volume
B) temperature
C) osmotic
D) partial pressure
E) chemical
Partial Pressure
The pressure that a single component of a gas mixture would exert if it occupied the entire volume of the mixture at the same temperature.
Osmotic Gradient
A difference in the concentration of solutes across a semipermeable membrane, which drives osmosis, the movement of water to balance solute concentrations.
- Expound on the chemical operations in gas exchange, highlighting the role of enzymes and the theory of concentration gradient.
- Gain an understanding of how gases are transferred across the respiratory membrane and what factors play a role in this process.

Final Answer :
D
Explanation :
Gases diffuse down a partial pressure gradient, which means they move from higher concentrations of pressure to lower concentrations of pressure. This is because gases naturally spread out to fill any available space, and will move from areas of higher pressure (i.e. more particles in a given area) to areas of lower pressure (i.e. fewer particles in a given area) until the pressure is equalized.
