Fractionation of carbon isotopes in oxygenic photosynthesis the bundle sheath cells. This limits the carbon available to RuBisCO, which in turn lowers its fractionation effect. This accounts for the overall delta value in C4 plants to be -12 to -16 ‰. Plants that use Crassulacean acid metabolism, also known as CAM photosynthesis, temporally separate their chemical reactions between day and night. This strategy modulates stomatal conductance to increase water-use efficiency, so is well-adapted for arid climates. During the night, CAM plants open stomata to allow CO to enter the cell and undergo fixation into organic acids that are stored in vacuoles. This carbon is released to the
What Do You Care What Other People Think? What Do You Care What Other People Think? "What Do You Care What Other People Think?": Further Adventures of a Curious Character (1988) is the second of two books consisting of transcribed and edited, oral reminiscences from American physicist Richard Feynman. It follows "Surely You're Joking, Mr. Feynman!". Richard Feynman received the Nobel Prize in Physics in 1965 for his contributions to the development of quantum electrodynamics. He is a theoretical physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, and the physics of the superfluidity of supercooled liquid helium, as
