Fractionation of carbon isotopes in oxygenic photosynthesis values more similar to C3 plants. In contrast to terrestrial plants, where CO diffusion in air is relatively fast and typically not limiting, diffusion of dissolved CO in water is considerably slower and can often limit carbon fixation in phytoplankton. As gaseous CO is dissolved into aqueous CO, it is fractionated by both kinetic and equilibrium effects that are temperature-dependent. Relative to plants, the dissolved CO source for phytoplankton can be enriched in C by about 8‰ from atmospheric CO. Isotope fractionation of C by phytoplankton photosynthesis is affected by the diffusion of extracellular aqueous CO into the cell, the
What You Won't Do for Love (song) What You Won't Do for Love (song) "What You Won't Do for Love" is a blue-eyed soul-styled single recorded by Bobby Caldwell for his eponymous debut album (1978). It was written by Caldwell and Alfons Kettner and released in by Clouds Records domestically and by TK Records internationally. After gaining a reputation in Miami clubs as a talented musician, Caldwell was signed to an exclusive contract with TK Records in 1978 by TK Records president Henry Stone. Heading to the studio, Caldwell recorded his first album, which was given a redo after Stone felt the album was good but "didn't
