Bioenergetics is the subject of a field of biochemistry that concerns energy flow through living systems. This is an active area of biological research that includes the study of thousands of different cellular processes such as cellular respiration and the many other metabolic processes that can lead to production and utilisation of energy in forms such as ATP molecules. This book presents current research from across the globe in the study of bioenergetics, including Cell ATP production by mitochondria; bioenergetics of closed ecological systems; bioenergetics of thermus thermophilus; as well as screening and studying photosynthetic mutants.
