Fractionation of carbon isotopes in oxygenic photosynthesis be less fractionated in C (ie, δC is relatively less negative) compared to C3 plants with low water-use efficiency. C4 plants have developed the C4 carbon fixation pathway to conserve water loss, thus are more prevalent in hot, sunny, and dry climates. These plants differ from C3 plants because the Calvin Cycle in C4 plants produces a four-carbon molecule, malate (rather than 3-phosphoglycerate), after fixation of CO. Malate, the four-carbon compound is the namesake of "C4" photosynthesis. This pathway allows C4 photosynthesis to efficiently shuttle CO to the RuBisCO enzyme and maintain high concentrations of CO within bundle sheath cells.
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
