They are strong reducing agents ( very negative redox potentials ) and function as electron carriers , for example in photosynthesis and nitrogen fixation 它们是强的还原性物质(很低的氧化还原电位)以及作为电子载体起作用,如在光合作用和固氮作用中。
On the other hand , the slow component of df is ascribed to the state qb - the next electron carrier of deoxidized side in ps ii . furthermore , we testified that the third component with lifetime much greater than the time of the registration period ( which is presented as a constant ) , is corresponds to the recombination of p680 + and the backward transport electron from ps i 延迟荧光的衰减动力学依赖于从q回流的电子( electron )与氧化态的p680 ~ + ,其中快相延迟荧光成份源于q _ a ~ -上电子回流与p680 ~ +的复合产生,慢相成份源于q _ b ~ =上电子的回流与p680 ~ +的复合产生。
