How many ATP or ATP equivalents would it take to translate the coding region of an mRNA that encoded 277 many amino acids? (Include the energy used to set up the ribosome, charge the tRNAs using an aminoacyl-tRNA synthetase, choose the correct tRNA, translocate the ribosome, and tear down the ribosome complex at termination. This answer will not include the energy required to synthesize the mRNA in the first place, only the energy to translate 1 polypeptide. I'm not sure...

1. Down at the ice skating rink you watch a customer try out the new exercise machine consisting of a large spring allowing the skater to oscillate back and forth. The skater (mass-64kg) is stretched 0.84m from equilibrium with a force 250N and remains at rest. At 0.84m from equilibrium, the skater is then pushed toward the equilibrium position. At a distance of 0.22m (from equilibrium), the skater has a speed of 2.4m/s. a) Starting with Newton's second law, show...
