Title: Week 8 - Unit 3_2: Membrane Transport Mechanism
Course: Biochemistry

Introduction

The plasma membrane is a selective barrier that maintains distinct internal and external environments by controlling the passage of molecules into and out of the cell. Several mechanisms are used for the transport of molecules across the membrane.

Expectations

This lesson is on transport across the cell membrane, we will learn in detail about the types of transport across the membrane

Course outline

1. Transport across the plasma membrane
2. Passive transport
3. Active transport
4. Bulk transport

Learning outcomes

At the end of this unit, you should be able to

- Distinguish different mode of transports across the biological membrane
- Compare simple diffusion and facilitated diffusion.
- Differentiate between channel proteins and carrier proteins.
- Predict the direction of water movement by osmosis.
- Distinguish between endocytosis and exocytosis.
- Illustrate how endocytosis can be specific.
