The term you are looking for is "redox reaction." This is short for reduction-oxidation reaction, which describes a chemical process involving the transfer of electrons between two species. In every redox reaction, one substance is oxidized (loses electrons) and another is reduced (gains electrons). This concept is fundamental in various biochemical processes, such as cellular respiration and photosynthesis, where redox reactions play a crucial role in energy production and storage.

In biological systems, redox reactions are often coupled with other metabolic pathways, allowing organisms to efficiently convert energy from nutrients into forms that can be used for cellular functions. This is particularly important in reactions involving molecules such as NADH and FADH2, which carry electrons in the electron transport chain during oxidative phosphorylation.

Overall, redox reactions are essential for maintaining the energy balance in cells and are integral to numerous biochemical pathways.
