Question
Chapter 39, Problem 15TYPSS
Summary Introduction
To review:
An experiment designed to illustrate the use of drug vanadate, which poisons proton pumps, to test the hypothesis that phosphate ions enter cells via an H+/HPO4 2 cotransporter.
Introduction:
The plasma membrane contains large amount of water; thereby, leading to high concentration of hydrogen within cell. The proton pump is a transmembrane protein involved in proton transport from a low region of concentration to a high concentration region across the cell membrane, mitochondria and other cell organelle.

A researcher created a group of osteoblasts with an Esp mutation that prevented the production of a functional Esp product (mutant).
