Examples include transport of large molecules non-lipid soluble and the sodium-potassium pump. Types of passive transport.
Learning Objectives Back to Top Materials are exchanged between the cytoplasm and external cell environment across the plasma membrane by several different processes, some require energy, some do not. Note, however, most of the common examples of diffusion also illustrate other mass transport processes.
Fick's laws contain only one parameter: the Diffusion Coefficient. States of matter What is diffusion? The particles collide with each other or with their container. A simple illustration of this process can be seen using a glass of water and food coloring. This motion is called a random walk and is illustrated in [link].
