Question
Chapter 5.4, Problem 3LO
Summary Introduction
To predict: The direction of water movement by osmosis.
Introduction: The movement of materials across the biological membrane may occur either passively or actively. Simple diffusion, osmosis, and facilitated diffusion are the three major types of passive transport. The major types of active transport are primary active transport and secondary active transport.
