Molecular and Cellular Biophysics

Logically organized from small-scale to large-scale systems, this text provides comprehensive coverage of both molecular and cellular biophysics using a quantitative approach. It first discusses the characteristics of living things and the evolution of life. The book then covers small-scale structures that include DNA, RNA, and hydrogen bonds, followed by large-scale systems, such as basal bodies, mitochondria, and vesicles. The author also examines the biophysical processes of oxidative phosphorylation, diffusion, exciton energy transfer, and cell division. In addition, the text includes numerous worked examples, exercises, references, and illustrations.

Résumé
From quantum theory to statistical mechanics, the methodologies of physics are often used to explain some of life's most complex biological problems. Exploring this challenging yet fascinating area of study, Molecular and Cellular Biophysics covers both molecular and cellular structures as well as the biophysical processes that occur in these structures. Designed for advanced undergraduate and beginning graduate students in biophysics courses, this textbook features a quantitative approach that avoids being too abstract in its presentation.Logically organized from small-scale (molecular) to large-scale (cellular) systems, the text first defines life, discussing the scientific controversies between mechanists and vitalists, the characteristics of living things, and the evolution of life. It then delves into molecular structures, including nucleic acids, DNA, RNA, interatomic interactions, and hydrogen bonds. After looking at these smaller systems, the author probes the larger cellular structures. He examines the cytoplasm, the cytoskeleton, chromosomes, mitochondria, motor proteins, and more. The book concludes with discussions on biophysical processes, including oxidative phosphorylation, diffusion, bioenergetics, conformational transitions in proteins, vesicle transport, subcellular structure formation, and cell division.
