They did not observe any liposomal (vesicular) transport and the experiment didn't work because they were missing a compound referred to as motor protein.
<h3>What is Motor protein?</h3>
This type of protein falls under the category of molecular motors which have the ability to move in the cytoplasm of cells. This is done by the conversion of chemical energy into mechanical work which is aided by the hydrolysis of ATP which serves as the energy currency of cells.
We were told that the microtubules were spontaneously lengthening and shortening but there was no liposomal transport which means there were no molecular motors to fuel the process when the experiment was performed.
This was because of a lack of motor protein which would have aided the movement of the liposomes which therefore explains the reason why it was chosen as the most appropriate choice.
