ribosomes

Introduction: Transport processes are based on the movement of matter when a force is exerted upon them (1). Diffusion, centrifugation, and electrophoresis are all based on forces causing movement or flow of particles. Diffusion is the migration of particles based on a concentration gradient. Sedimentation and electrophoresis are two transport processed in which the force exerted serves to separate particles. Sedimentation depends upon an increase in centrifugal force to cause a flow of matter. Electrophoresis is …
