Mooresitesurface %J The Open Enzyme Inhibition Journal %D 2008 %I %R 10.2174/1874940200801010001] %X We examine theoretically the ability of diffusible cytoplasmic carriers to facilitate delivery of substrate to sites within biological membranes. Two processes are analyzed. In one, delivery of Ca to a site on a membrane surface is examined. As a contrasting example, chelator-supported diffusion to a uniform absorbing surface is considered. %U http://www.benthamscience.com/open/toeij/articles/V001/1TOEIJ.htm
