Figure 2.6: (a) Kinesin motors on a surface create a street and move attached microtubules. The micro-

tubules carry multilamellar vesicles. (b) The kinesin can move the microtubules, and with that the vesicles

move so fast that the vesicles hit each other with enough force to fuse into a lipid-tube system that mimics

the cellular endoplasmic reticulum (ER) (adapted from [19]).
