Researchers investigating the mechanism of vesicle transport assembled a cell-free system that included microtubules, vesicles, and ATP. However, they observed no movement of transport of vesicles because the mixture was missing which of the following components?
A) mitochondria
B) contractile microfilaments
C) Golgi apparatus
D) motor proteins
