acceptori

Acceptori is a term used in several languages as the plural form of acceptor. In scientific contexts it designates an entity that accepts something, such as electrons, protons, or a chemical group, during a process. The precise meaning depends on the discipline and language.

In chemistry and biochemistry, an acceptor is a substance that receives an energetic particle or group. Electron acceptors are central to redox reactions: they draw electrons away from donor species. In biology, the concept is prominent in respiration and photosynthesis. For example, molecular oxygen acts as the final electron acceptor in aerobic respiration, while NADP+ serves as an electron acceptor in the light reactions of photosynthesis. Lewis acids can also be described as electron pair acceptors in various catalytic and coordination chemistry contexts.

In materials science and catalysis, acceptors refer to species that receive atoms or functional groups during a transfer step or a reaction, influencing reaction pathways and product formation.

Language notes: Acceptori is the plural form used in non-English texts for the same concept. In English, the standard plural is acceptors. The term derives from Latin accipere, meaning “to take” or “to receive.”
