Protein synthesis is a process in which organelles work together
to synthesize a mature protein. Which statement best describes
the process by which mature functional proteins are produced?
The rough endoplasmic reticulum manufactures proteins and

Act as an electrical unit.
A variety of physiologic mechanisms are employed to transport
fluid and solutes across the cell membrane. Which one of them is
described by the equation J = [D(A) (Cin - Cout)]/X?
