The rate of diffusion of a molecule into a cell is affected by which of the following factors?

The rate of diffusion is significantly influenced by factors such as the concentration gradient, temperature, and the size of the molecule. A greater concentration difference across a membrane typically accelerates diffusion, while higher temperatures increase molecular movement, facilitating faster diffusion. Additionally, smaller molecules usually diffuse more readily than larger ones due to less resistance in the surrounding medium. Another cool aspect is the role of the membrane's permeability. Cell membranes are selective barriers; they allow certain molecules to pass through more easily than others. For example, nonpolar molecules tend to diffuse across membranes faster than polar molecules, which may require specific transport proteins to aid their journey into the cell!
