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 Cha' Gonna Do for Me highest charting album until her 80's-era breakthrough "I Feel For You". Its popularity among jazz audiences was likely due to the inclusion of the Dizzy Gillespie composition "Night In Tunisia" with a guest appearance by Gillespie himself as well as what today would be called a 'sample' of Charlie Parker's legendary four bar alto break from his 1946 recording of the title. Khan's vocal interpretation also features lyrics written by the singer herself. This album was nominated for Best R&B Vocal Performance, Female in 1981. Two tracks from the "What Cha Gonna Do For Me" sessions were only released as
