Yоu аre cоnducting reseаrch оn а muscle-wasting disease in cats, and you need to know how a potential drug molecule (let's call it X) enters the muscle. Is it simple diffusion through the lipid bilayer, protein-mediated diffusion, or some sort of active transport? Suppose that you can culture cat muscle cells in a petri dish, add X to the bathing saline, and measure the concentration of X inside the muscle after various periods of time. Question: What step below would be ESSENTIAL for measuring the transport RATE of X  (i.e., amount of X entering the cells per unit time)?
