Factors that can increase the rate of diffusion include increasing the concentration gradient, increasing temperature, decreasing the distance for diffusion, increasing surface area, and reducing the size of the molecules diffusing. Factors that can decrease the rate of diffusion include decreasing the concentration gradient, decreasing temperature, increasing the distance for diffusion, decreasing surface area, and increasing the size of the molecules diffusing.
The rate of diffusion should also increase due to the increased likelihood of substrate-carrier complex formation. The rate will increase proportionally with the increase in carriers until a threshold is reached and a plateau in rate will occur. This is designated as Vmax
Oxygen diffusion increases as the need increases. It is a matter of supply and demand.
Temperature affects the rate of diffusion because higher temperatures increase the kinetic energy of particles, causing them to move faster and collide more frequently. This increased movement results in quicker diffusion as particles spread out more rapidly. Conversely, lower temperatures decrease particle movement and slow down the rate of diffusion.
The net increase or decrease of individuals over time is determined by comparing the birth rate and immigration rate to the death rate and emigration rate. A positive difference indicates a net increase, while a negative difference indicates a net decrease in the population.
Decrease in temperature and increase in pressure.
