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 You Need (song) What You Need (song) "What You Need" is a song recorded by the Australian band INXS. It is the leadoff track from their 1985 album, "Listen Like Thieves". "What You Need" was the first single off the album in Australia and New Zealand, while it was in USA and Europe the second single after "This Time" and was the band's first American Top Ten hit, peaking at #5 on the "Billboard" Hot 100 singles chart. After the album "Listen Like Thieves" was recorded and ready to be given to the record label for inspection, producer Chris Thomas was worried that
