WebMar 20, 2024 · By 'H carrier', I think the author means 'a proton plus an electron carrier' or a H atom carrier. When PQ accepts an electron, is may also pick up a proton from the outside (it now has accepted a H, that is a proton plus an electron). If the electron is donated to another acceptor, a proton may be lost on the inside. WebDec 27, 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 photosynthetic …
