Intracellular pH (pHi) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid. The pHi plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pHi, biological cells may have compromised function. Therefore, pHi is closely regulated in order to ensure proper cellular function, controlled cell growth, and normal cellular pro… WebJan 1, 1998 · The change in cytoplasmic pH is sufficient to induce the expression of the MarA locus leading to changes in gene expression at other loci. pH SENSING Both adaptive gene expression and the ability to regulate pHi imply a capacity to sense changes in pH at the cell surface and in the cytoplasm.

WebJan 1, 2013 · The intracellular pH of living cells is strictly controlled in each compartment. Under normal conditions, the cytoplasmic pH (pHc) and the vacuolar pH (pHv) of typical plant cells are maintained at slightly alkaline (typically 7.5) and acidic (typically 5.5) values, respectively. A failure to maintain the pH homeostasis of cells leads to cell ... 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. WebAug 1, 1998 · Average cytoplasmic pH in trichoblasts (B) and atrichoblasts (C) was calculated from the ratio images using IPLabs image analysis software using a 5-10 μm region of the cytoplasm as indicated in the insets in A.
