Some medicines are delivered in capsules of artificial vesicles to be swallowed. Would this method be best...?

Question

..for delivering medicines that act on target proteins in the plasma membrane, the mitochondria, or the cytosol? Explain.
Thanks in advance, this was pretty tricky for me.

or delivering medicines that act on target proteins in the plasma membrane, the mitochondria, or the cytosol? Explain.

Its not asking what method is best, its asking which organelle is best targeted for using this type of medicine

Answer 1

There is really no "best" method for delivering medicines. Some medicines are proteins and would be digested by the gut if ingested. These would be better delivered intraveinously. An example of this would be insulin for diabetics. Vaccines have a variety of delivery methods. Polio is delivered on a sugar cube to the gut while flu vaccine is given intramusclearly in a shot. So it really depends on what you're trying to do.

Answer 2

You are referring to something called a liposome. Liposomes are used to get things into a cell, since by themselves, anything hydrophilic would not pass through the membrane. However, a ball of phospholipid can fuse with the plasma membrane, and deposit its contents into the CYTOPLASM. Liposomes can also be used to deliver contents to the plasma membrane. By embedding things into the membrane of the liposome, when it fuses with the cells membrane, the contents will be lodged in the cell membrane.
