Chapter 10, Problem 18CQ

Summary Introduction

To calculate: The time taken by 100 molecules of Valinomycin to transport enough K⁺ ions to change the concentration inside an erythrocyte of the given volume.

Concept introduction: Valinomycin is the characterized ionophore that specially binds to the K⁺ ion. It is a cyclic ionophore that contains ester linkage as well as peptide bonds, and D-amino acids and L-amino acids. Valinomycin is the channel-forming ionophore that forms transmembrane channels or pores through which the selected ions can pass through.
