Below find the structures for ibogaine and cocaine.
Ibogaine and cocaine inhibit the dopamine active transporter (DAT). This transporter is a secondary active transporter, and depends on the primary active transporter Na+/K+ ATPase. Ibogaine had a Kι = 2 μM, and cocaine a Kι = 0.64 μM respectively.
(a) Define secondary active transport.
(b) Is ibogaine an effective treatment for cocaine based on DAT binding?
Ouabain is a specific inhibitor of the active transport of sodium ions out of the cell and is therefore a valuable tool in studies of membrane transport mechanisms. Which of the following processes in your own body would you expect to be sensitive to inhibition by ouabain? Explain your answer in each case.
a) Facilitated diffusion of glucose into a muscle cell
b) Active transport of dietary phenylalanine across the intestinal mucosa
c) Uptake of potassium ions by red blood cells
d) Active uptake of lactose by the bacteria in your intestine
What limits the activity of intracellular mediators, such ascGMP, and phosphorylated proteins?

There is a sodium gradient across the synaptic vesicle membrane, and it provides the driving force for the transport of neurotransmitter into the vesicle. c.) There is a proton gradient across the synaptic vesicle membrane, and it provides the driving force for the transport of neurotransmitter out of the vesicle. d.)
