Bioenergetics is about how living cells obtain, transfer, and use energy to power all their activities. It focuses on the flow of energy through biological systems—from extracting energy from nutrients, to capturing that energy in carriers like ATP, to using it for cellular work, growth, and maintenance. This makes it distinct from metabolism in general, which covers all chemical reactions in a cell, not just energy changes. It’s not a general physics topic about energy, and it isn’t limited to ecosystems’ energy conservation. The concept centers on energy transformations and the cellular mechanisms that drive biological processes.
