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 You Won't Do for Love (song) What You Won't Do for Love (song) "What You Won't Do for Love" is a blue-eyed soul-styled single recorded by Bobby Caldwell for his eponymous debut album (1978). It was written by Caldwell and Alfons Kettner and released in by Clouds Records domestically and by TK Records internationally. After gaining a reputation in Miami clubs as a talented musician, Caldwell was signed to an exclusive contract with TK Records in 1978 by TK Records president Henry Stone. Heading to the studio, Caldwell recorded his first album, which was given a redo after Stone felt the album was good but "didn't
