- Discuss why the following affect the rate of diffusion:molecular size, temperature, solution density, and thedistance that must be traveled.Usually , rates of diffusion vary inversely with molecular weights; so smaller molecules diffuse faster than do larger ones. In cells, however, calcium ion diffuses more slowly than does cAMP. Propose a possible explanation.Simple diffusion is defined as the movement of?
- • What are the ionic differences between the extracellular and intracellular fluids? • Give the theory of the diffusion process.Two students are discussing the effect of concentration gradient on diffusion. Student A says, “The higher the concentration gradient, the slower the rate of diffusion.“ But student B thinks the opposite. Who is correct?Diffusion is the movement___.
