Membrane Bioenergetics

Vladimir P. Skulachev

en Limba Engleză Paperback – 23 aug 2014

Membrane bioenergetics is one of the most rapidly growing areas within physico-chemical biology. Main aspects treated in this book include energy conservation and utilization by membrane-linked molecular mechanisms such as intracellular respiration, photosynthesis, transport phenomena, rotation of bacterial flagella, and the regulation of heat production.
