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 would Jesus do? expression has become a snowclone, sometimes for humorous effect. For example, "What Would Jesus Buy?", "What Would Lincoln Do?", "What Would Brian Boitano Do?", "What Would Mary Marvel Do?", "What Would Johnny Cash Do?", and "What would Tintin do?". The term "What Would Jesus Do?" or "WWJD" is also perceived as a fundamental management and leadership principle given Jesus' methodology of going to the marketplace to preach and lead by example. In modern management principles, more academic and professional references are going to the gemba or Management by Walking Around. What would Jesus do? The phrase "What would Jesus do?"
