Document Summary
But when gtp is lost the microtubule shrinks really fast. This is because the individual protofilaments have weak bonds they separate when the cap is lost. But since the mico-dimers have strong bond, they stay together. And these leads to curling!! (the er and golgi are located in the cell body) *motor proteins use atp to move along the microtubules for transporting organelles. By the signal they can change their direction. Treadmillling range: at one point there, they reach a critical concentration(equilibrium) D. in a band that moves from the plus to the minus end. (this couljd be ans if it is pulse! Myosinii along actin filaments causes muscles to contract. A. dynein (to position near nucleus, it should move to ends,,,, so it is dynein) Myosin ii (+ end directed: microtubule motor proteins: They all couple atp hydrolysis with conformational changes to generate force. All move in a specific direction along filaments that have polarity (plus/minus end).
