Imagine a charged molecule called "FinalExamium" andpretend that every cell in the human body has to maintain steadylevels of FinalExamium in the cytoplasm. Presume FinalExamiumdoes not exist outside of human cells and that synthesis ofFinalExamium is an endergonic process. FinalExamium isconsumed in the process of translation, so levels of FinalExamiumdrop more rapidly as the rate of translation increases. Which ofthe following must exist in the cell (or cell membrane)? Choose every correct answer:
a.
An enzyme that regulates movement of FinalExamium across thecell membrane
b.
A molecule that binds to FinalExamium and changes shape
c.
A molecule that uses an energy source (like ATP) to catalyze achemical reaction involved in the synthesis of FinalExamium
