This manual on "Dynamics of Membrane Proteins and Cellular Energetics" is the result of a FEBS-CNRS Course held in Grenoble and Besanc;{on in September 1987.' It appears to be, after the first, published in 1979 the fifth of the series. After focussing on the "Biochemistry of Membranes" (1979) it was the turn of "Membrane Proteins" (1981) and of Enzymes, Receptors and Carriers of Biological Membranes (1983), fo1- wed by "Membrane Proteins Isolation and Characterization" ( 1986) . Al though the central issue has always been the its components and its functions, each biological membrane, manual...
