A New Look at Mechanisms in Bioenergetics is a collection of lectures given at the Robbins Lectures at Pomona College in April, 1973. The lectures contained in the book are based on laboratory works on oxidative phosphorylation. The text starts by defining oxidative phosphorylation, and after which, began a series of discussions on the biochemical approach to the problem of photophosphorylation; functions and structure of membranes and the mechanism of phosphorylation coupled to electron transport; and the basic principle of the control that governs both glycolysis and oxidation. Biochemists and biologists will find the book interesting and amusing.
