Examine the molecular model of the partial structure of the yeast atp synthase. which part of the molecule spans the inner mitochondrial membrane?

ATP synthase or Complex V spans the inner mitochondrial membrane. ATP synthase and respiratory chain are biochemically SEPARATE systems and they are linked only by PROTON MOTIVE FORCE. Proton motive force is generated by electron transport.

ATP synthase resembles a ball on a stick which locates in the inner mitochondrial membrane. The answer is FO rotor.

Some of her  assignments would be creation of drugs. she is a medical chemist after all so she'd need to have the necessary knowledge to make medicine which can later be sold in a pharmacy 

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
