Question
Chapter 5.4, Problem 19CC
Summary Introduction
To determine: The type of particles that passes through the open channels.
Introduction: The membrane channels that are also known as transmembrane channels are the pores within the lipid bilayer of the cell membrane. These channels regulate the movement of particles across the membrane.
