A kinesin that is transporting a secretory vesicle uses approximately 80 ATP molecules/s. Each ATP provides a kinesin molecule with an energy of about 0.8 × 10-19 J. If the velocity of the kinesin is 800 nm/s, can you determine the force the kinesin is exerting, if you assume that all the ATP energy is used (100% efficiency)? If you can, find it and give your answer in newtons. If not, answer with 0.

The force is  

Explanation:

From the question we are told that

     The rate at which ATP molecules are used is

       The energy provided by a single ATP is  

       The velocity of the kinesin is  

The power provided by the ATP in one second is  mathematically represented as

substituting values

Now  this power is mathematically represented as

Where  F  is  the force the kinesin is exerting

  Thus  

substituting values

when it gains or loses electrons

less than one you can't create energy
