The gastric h' pump found in the plasma membrane of gastric mucosa cells maintains a cytostolic concentration of k of 145 mm and an h concentration of 3.16 x 10m . in the stomach, the concentration of k is 10 mm and the h ion concentration is 0.15 m. (a) (2 pts) what is the ph of the cytosol of gastric mucosa cells and what is the ph of the stomach? (b) (2 pts) what is the change in free energy of transporting 1 mole of h from the cytosol into stomach at 37 °c? f=96,500 j/mol. v, r = 8.3145 j/mol k. the transmembrane electrical potential is + 70 mv (cytosol - stomach ). (c) (2 pts) what is the change in free energy of transporting 1 mole of kfrom the stomach into cytosol at 37°c? f-96,500 j/mol. v,r-8.3145j/mol k. the transmembrane electrical potential is - 70 mv (stomach - cytosol). (d) (2 pts) what is the change in free energy of transporting 1 mole of h from the cytosol into stomach and 1 mole of k from the stomach into cytosol at 37 °c? f=96,500 j/mol v. r=83145 j/mol k. the transmembrane electrical potential is - 70 mv (stomach -- cytosol). (e) (2 pts) is this transport ex ergonic or endergonic? _ (f) (2 pts) under cellular conditions in the gastric mucosa cell, the free energy change for the hydrolysis of atp is around - 70 kj/mol. what is the change in free energy of transporting 1 mole of h' from the cytosol into stomach and 1 mole of k from the stomach into cytosol at 37 "c? 96,500 j/mol. v.r-8.3145 j/mol k. the transmembrane electrical potential is - 70 mv (stomach + cytosol),when the transport is coupled with atp hydrolysis? (g) (2 pts) what type of transport is this?
