Ive already answered A) and B). If they are wrong let me know but otherwise I just included them to show background information on the problem. Thanks!!

14.)

(A) (1 pt) Draw the structure of 1-myristoyl-2-linoleoyl-3-phosphatidylserine in the ionic form that would predominate at physiological pH. What is the net charge of this molecule at physiological pH? ANSWERED: net charge is -1

(B) ( 3 pts) In the plasma membrane of erythrocytes, the concentration of phosphatidylserine on the extracellular side of the membrane is 2.32 microM, the concentration of phosphatidyl serine on the cytosolic side of the membrane is 615.56 microM. The transmembrane potential is -70 mV going from the extracellular side of the membrane into the cytosol. What is the free energy change associated with the transverse diffusion of phosphatidylserine from the extracellular side of the membrane to the cytosolic side. Show your work and clearly state your units. T = 37oC, F = 96,500 J/mol(V), R = 8.3145 J/mol(K)

ANSWERED: 21.14 kJ/mol

(C) ( 2 pts) Name the protein that transports phosphatidylserine from the extracellular side of the membrane to the cytosolic side.________________________________-

(D) ( 2 pts) How does this protein make this transport exergonic?

(E) ( 2pts) This is an example of what type of transport?___________________________________
