The pH of apoplastic space … 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 … Visa mer Intracellular pH is typically lower than extracellular pH due to lower concentrations of HCO3 . A rise of extracellular (e.g., serum) partial pressure of carbon dioxide (pCO2) above 45 mmHg leads to formation of Visa mer There are several common ways in which intracellular pH (pHi) can be measured including with a microelectrode, dye that is sensitive to pH, or with nuclear magnetic resonance techniques. For measuring pH inside of organelles, a technique utilizing pH-sensitive green … Visa mer The pH within a particular organelle is tailored for its specific function. For example, lysosomes have a relatively low pH of 4.5. Additionally, fluorescence microscopy … Visa mer
