...shown that the unit responsible for the transport of citric acid--essential for the combustion of fuels in all cells--across a cell membrane, can be altered by repression as well as by mutation. This discovery offers a powerful tool for approaching one of the least-understood aspects of cellular physiology--the remarkable capacity of cell membranes to select only certain substances for passage in and out of the cell...
Berry described the mechanism that acts in the cell membrane to permit the passage of substance as one of the major mysteries of cell physiology...
