It can be described as the study of energy relationships and energy transformations and transduction in living organisms. It includes the study of thousands of different cellular processes and the many other metabolic and enzymatic processes that lead to production and utilisation of energy in forms such as ATP.
The goal of bioenergetics is to describe how living organisms acquire and transform energy in order to perform biological work. The study of metabolic pathways is thus essential to bioenergetics.
Glycogenesis, gluconeogenesis, and citric acid cycle are examples of bioenergetic processes.
