Its energy source is glucose, which it is taking up from its environment via na/glucose symporters distributed throughout the surface of its plasma membrane. by briefly adding an inhibitor of all glucose breakdown, you are able to determine that glucose accumulates in the cell at the rate of 45 μm/hr. based on this number, how many μmoles of glucose must be entering the cell per hour? (assume that one-half of the volume of the cell is composed of organelles, and thus not available for diffusion of glucose)

One of the newest applications of cell technology is called cybrid embryos. this process involves replacing the nuclear material of an animal cell with human nuclear material. how might this process affect public policies about research by using stem cells? the same policies and concerns about the use of human embryonic stem cells would most likely apply. the embryos would most likely be treated like traditional animal embryos and regulated accordingly. the process of forming cybrid embryos would most likely be banned by government regulators. the embryos would be treated as regular cells because they are not fully human in origin.
