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
What Do You Take Me For? What Do You Take Me For? "What Do You Take Me For?" is a song by English singer Pixie Lott from her second studio album, "Young Foolish Happy" (2011). The song features American rapper Pusha T and was released on 4 November 2011 as the album's second single. The track received its first play on Capital FM on 26 September 2011.
