- Discuss why the following affect the rate of diffusion:molecular size, temperature, solution density, and thedistance that must be traveled.arrow_forwardIdentify and explain two examples of diffusion you have experienced. Provide specific details in your explanation relating to the concept of diffusionarrow_forwardThis graph shows facilitated diffusion of a compound across a cytoplasmic membrane and into a cell. As the external concentration of the compound is increased, the rate of uptake increases until it reaches a point where it slows and then begins to plateau. This is not the case with passive diffusion, where the rate of uptake continually increases as the solute concentration increases. Why does the rate of uptake slow and then eventually plateau with facilitated diffusion?arrow_forward
- Discuss the difference in the solute concentration gradient and rate of diffusion between simple diffusion and facilitated diffusion.arrow_forwardProvide an example of how multiple membrane transport proteins typically work together to move a molecule across a membrane (your example can be general or use hypothetical proteins).arrow_forwardWhich of the following are features of facilitated diffusion? There may be more than one correct answer, select all that apply. Requires energy Movement assisted by proteins Can include passive diffusion Depends on ATP hydrolysis Can include ion transport down its concentration gradient in a cell (high to low concentration)arrow_forward
