Question
Chapter 10, Problem 9E
Summary Introduction
To explain: The reason for which H2O cannot pass through the KcsA K+ channel.
Concept introduction: Potassium ions passively diffuse from the cytoplasm to the extracellular space by trans-membrane proteins named as K+ channel. KcsA K+ channel is the K+ channel from Streptomyces lividans. KcsA is a 158-residue integral membrane protein.
