Caption

Kinesin with vesicle is attached with two "feet" to the cell's microtubule. This is a safe and stable time period. The kinesin untethers its back foot and moves it forward. This is a vulnerable time period when the whole complex could lose its grip. Finally the loose foot attaches to the microtubule in front and the system is once again stable.
