Chapter 4, Problem 4RQ

Summary Introduction

To review:

The mechanisms of transporting nutrients in prokaryotes and eukaryotes along with the description of facilitated diffusion, coupled transport, ABC transporters, group translocation, and endocytosis.

Introduction:

All living organisms require nutrients to carry out their basic life processes. The transport and metabolism of nutrients plays a vital role in the life cycle of living organisms. The process by which the substances are transferred across the cell membrane is called transport. Some molecules can simply cross the phosphor-lipid bilayer, while others need special transport proteins to move across the membrane.
