Question In animal cells the intracellular cytosolic pH is

Question In animal cells the intracellular cytosolic pH is tightly regulated and maintained t 7 2 Several types of cotransport proteins are involved in the regulation of the cytosolic pH As shown in the figure the activity of three cotransport proteins that regulate the cytosolic pH changes with pH The direction of ion transport is indicated above the curve for each protein Assume that all these three cotransport proteins are present in a cell explain how they help to maintain the cytosolic pH at about 7 2 by answering the following questions 2 For each protein use your best judgment to indicate the movement of which ion provides the driving force for the protein to pump other ion s across the cytoplasmic membrane Give a brief reason to support each answer 100 Percent maximal rate of ion transport 50 DO Na CI Na HCO 6 8 7 0 Intracellular pH 7 2 7 4 HCO 7 6
