The transfer of electrons from one molecule to another is called an oxidation-reduction, or redox reaction. A molecule that loses electrons is oxidized; a molecule that gains electrons is reduced. Different molecules have different tendencies to gain or lose electrons, called the redox potential. crave brothers farm llcWitryna27 gru 2024 · Introduction. CO 2 is reduced and assimilated into carbon rich molecules via photosynthesis, 30%–60% of which are oxidized by respiration and released back to the environment as CO 2 during the plant lifecycle (Raich et al., 2014; Amthor et al., 2024).Beyond this simple comparison, however, the systems that underlie … crave brand cookies
