Fractionation of carbon isotopes in oxygenic photosynthesis product 3-phosphoglycerate is depleted in C due to the kinetic isotope effect of the above reaction. The overall C fractionation for C3 photosynthesis ranges between -20 to -37‰. The wide range of variation in delta values expressed in C3 plants is modulated by the stomatal conductance, or the rate of CO entering, or water vapor exiting, the small pores in the epidermis of a leaf. The δC of C3 plants depends on the relationship between stomatal conductance and photosynthetic rate, which is a good proxy of water use efficiency in the leaf. C3 plants with high water-use efficiency tend to
Do What You Do (Jermaine Jackson song) the past: "Why don't you do what you do / when you did what you did to me?" Its B-side is "Tell Me I'm Not Dreamin' (Too Good to Be True)", a duet with Michael Jackson. The song was sampled by Lil Wayne for "How Could Something" and by Chamillionaire for "Void In My Life". The music video was an imitation of "The Godfather" and supermodel Iman played Jackson's love interest who eventually betrays him by trying to shoot him. After his henchmen take her away, it is not revealed what happened to her. Do What You Do (Jermaine Jackson
