cytosolic pH is tightly regulated and maintained to 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 1 Give a name to each cotransport protein e g ion1 ion2 symporter etc Percent maximal rate of ion transport 100 Na Na HCO3 CI 6 8 7 0 Intracellular pH 7 2 7 4 HCO3 7 6
