Question
Chapter 5, Problem 7RQ
Summary Introduction
To determine:
The protein that allows facilitated diffusion of water and also determines the experiment that demonstrated the function of this protein.
Introduction:
A cell membrane is made of different molecules like phospholipids, proteins, and cholesterol that contribute to the flexible nature of a cell membrane. A cell membrane is selectively permeable in nature which means it allows selective substances to enter the cell. The movement of molecules could be passive like in osmosis and diffusion, active transport or facilitated transport.
