What organelles will it pass through

Q1. Suppose you are the lead scientist in a cytology lab, studying active transport and “cell eating.” You have placed a radioactive marker on a bit of food that was taken into the cell through endocytosis. Trace the pathway this particle would probably take while moving from outside the cell to inside. What organelles will it pass through? Where will it be located within these organelles?

Q2. What is intracellular Cl- concentration if the membrane is permeable to Cl- and Cl- is at electrochemical equilibrium at the membrane voltage of -84 mV (negative inside)? Extracellular Cl- concentration= 107mM. Show the calculation.
