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. Your research suggests that drug X enters cat muscle cells by active transport mediated by a specific protein in the cell membrane. To further test this preliminary result, you develop a molecule very similar to X (let's call it Z). Z will bind to (and be transported by) the transporter protein, just like X. Question: You prepare two experiments. In the first experiment (A), you only add X to the bathing saline. In the second experiment (B), you add the same amount of X molecules into the saline as in A, plus an equal, additional amount of Z molecules. What would you most likely observe as you conduct these experiments:
