Chapter 5.4, Problem 3C
Summary Introduction

To determine: The direction of net movement of particles along their concentration gradient.

Concept introduction: Diffusion is a process that is characterized by the net transfer of molecules down a concentration gradient that results in the unsystematic movement of particles. There are two main types of diffusion namely simple diffusion and facilitated diffusion.

Summary Introduction

To determine: Whether the direction of the net movement of particles along their concentration gradient would be different in facilitated diffusion when compared with simple diffusion.

Blurred answer
Students have asked these similar questions
In what direction is there a net movement of particles along their concentration gradient? Would your answers be different for facilitated diffusion compared with simple diffusion?
Without saturation of transport proteins and under the same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion?
What is the difference between simple and facilitated diffusion? Facilitated by which type of molecule does the term “facilitated” mean?
