WebInternal cytoplasmic pH can be estimated from the optimal pH of intracellular enzymes. For example, α-galactosidase from an alkaliphile, Micrococcus sp. strain 31-2, had its optimal catalytic pH at 7.5, suggesting that the internal pH is around neutral. The proportion of cell volume that is cytosol varies: for example while this compartment forms the bulk of cell structure in bacteria, in plant cells the main compartment is the large central vacuole. The cytosol consists mostly of water, dissolved ions, small molecules, and large water-soluble molecules (such as proteins). The majority of these non-protein molecules have a molecular mass of …
