aerobic respiration, particularly the electron transport chain, and you are able to measure the intracellular pH as well as the pH in the immediate extracellular area or periplasm. In an actively respiring cell. which side of the plasma membrane would have the lower pH? The pH on the extracellular side would be lower than the pH on the cytoplasmic side. The pH on the cytoplasmic side would be lower than the pH on the extracellular side. The pH on both sides of the membrane would be the same.

Step 1
Step 1: In the electron transport chain, electrons are passed along a series of protein complexes, which pump hydrogen ions (protons) from the mitochondrial matrix to the intermembrane space. Show more…

Compare the pH of the mitochondrial matrix and the intermembrane space. The pH is lower in the matrix. The pH is lower in the inter membrane space. The pH in both regions is the same. The comparison of the pH varies from moment to moment depending on energy needs of the cell.

Calculate the minimum pH difference across a membrane that could, support the formation of 1.0 mM ATP from Pi and 1.0 mM ADP at pH 7 at 25 degrees.

DRAW UU The graph here shows the pH difference across the inner mitochondrial membrane over time in an actively respiring cell. At the time indicated by the vertical arrow, a metabolic poison is added that specifically and completely inhibits all function of mitochondrial ATP synthase. Draw what you would expect to see for the rest of the graphed line, and explain your reasoning for drawing the line as you did.
