Physiologically normal intracellular pH is most commonly between 7.0 and 7.4, though there is variability between tissues (e.g., mammalian skeletal muscle tends to have a pHi of 6.8–7.1). There is also pH variation across different organelles, which can span from around 4.5 to 8.0. pHi can be measured in a … Visa mer Intracellular pH (pHi) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid.
