Fractionation of carbon isotopes in oxygenic photosynthesis Calvin cycle during the day, when stomata are closed to prevent water loss, and the light reactions can drive the necessary ATP and NADPH production. This pathway differs from C4 photosynthesis because CAM plants separate carbon by storing fixed CO in vesicles at night, then transporting it for use during the day. Thus, CAM plants temporally concentrate CO to improve Rubsico efficiency, whereas C4 plants spatially concentrate CO in bundle sheath cells. The distribution of plants which use CAM photosynthesis includes epiphytes (e.g., orchids, bromeliads) and xerophytes (e.g., succulents, cacti). In Crassulacean acid metabolism, isotopic fractionation combines the effects of
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
