Chapter 6, Problem 7cCP
Summary Introduction
To review:
The process of active transport, and differences between active transport and facilitated diffusion.
Introduction:
Specific transport proteins and channel protein mediate the passage of small molecules across the membrane. The molecules move from a region of high concentration to low concentration in the case of passive transport. There are three types of passive transports namely diffusion, osmosis, and facilitated diffusion.
