In the stomach, parietal cells are responsible for the formation of the gastric juice. During acid
secretion, the pH in the stomach is estimated to be pH = 2, whereas parietal cells maintain an
intracellular pH =7.35. The transmembrane potential of parietal cells is typically -70 mV. Body
temperature 37°C.
1) Calculate the proton gradient concentration across the parietal membrane
2) Calculate the free energy change associated with the secretion of 1 mole of H*
3) Do you think that Ht transport can be driven by ATP hydrolysis at the ratio of one
molecule of ATP per H* transported? You can use your textbook or other sources to
check AG for ATP hydrolysis
4) If H* where free to move back to into the cell, calculate the membrane potential that
would be required to prevent them to do so
A lab made cell consisting of an aqueous solution enclosed in a semipermeable membrane is immersed in a beaker containing a

Liposomes are simply vesicles with a phospholipid bilayer that contain an inner aqueous compartment. Hydrophilic compounds could be carried in the buffer inside the liposome or hydrophobic drugs within the membrane itself. For instance, the Moderna and Pfizer mRNA vaccines actually use liposome technology to deliver the SARS-CoV-2 spike mRNA to human cells. The liposomes fuse with the plasma membrane allowing the contents of the liposome to enter the cytosol of cells. Of course, once the mRNA is in the cytosol is can be translated to protein on a ribosome. Explain why nucleic acid won’t get through the plasma membrane on its own. Discuss the energetic restrictions to movement through the membranearrow_forwardhosphate buffered saline (PBS) is a buffer solution commonly used in biological The buffer helps to maintain a constant pH. The osmolality and ion concentrations of the solution usually match those of the human body. You need to prepare a stock solution at pH 7.00 with NaH2PO4 and Na2HPO4 (pKa =7.21). What would be the respective concentration of these substances if you wish to obtain the final phosphate concentration [HPO4 −2] + [H2PO4 −] = 0.3 M?
