Question

Conditions:

[Na+] outside = .3 mM

[Na+] inside the presynaptic cell = .01 mM

[dopamine] inside = .5 mM

[dopamine] outside = .001 mM

ΔGinward = RT ln [X] inside/[X] outside + z F Vm

F = 23,000 cal/mol V

R = 1.987 cal/ mol K

Membrane potential is .07 V

Temperature is 273 K

Using the attachment and information above, please answer the following questions below:

( Is the concentration of dopamine higher on the inside or the outside of the presynaptic cell? SHOW your work.

2.) Would the movement of dopamine INTO the presynaptic cell be active or passive? SHOW your work.

Expert Solution

Step 1

Active transport

It is defined as the transport of molecules across the cell membrane with the need of energy . In this movement the transport takes place against the concentration gradient, that is from high concentration to low concentration.
