Unit 2 – Cell Structure and Function

Microtubule videos

  1. Organelle movement along microtubules: LINK (so organelles are moved in this way by motor proteins, ex. Kinesins and Dyneins)
  2. Microtubule Dynamics: LINK (see how large the network of microtubules really is!)
  3. Kinesin Walking: LINK (here is what is happening at the cellular level, the motor protein Kinesin is, when powered by ATP, actually walking as it carries organelles or vesicles along the microtubules)
