Document Summary
Eukaryotic cells are much larger than the cells of prokaryotes. In unicellular eukaryotes this means being able to swallow archaea and bacteria. The relative small portion of cytosol reduces the effect of the surface area with. The fluid portion of the plasma membrane and these organelles respect to the amount of waste produced. I. e. if a fatty acid was damaged, it could be recycled in a different organelle. First, substrates become localized at high concentrations in an organelle. Second, if the substrate was used up in one part of the organelle, other substrates may enter that have a short distance to diffuse. Third, groups of enzymes can be in/ on the organelle to speed things up. These all work together to help speed things up by catalyzing the. 4 key differences between pro and eu cells preceding reaction. Eu chromosomes are found in in a membrane bound nucleus. Eu cells have a lot of internal membrane bound organelles.
