You are conducting research on a 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: If X is taken up by simple diffusion through the lipid bilayer, how will the rate of drug X entry into the cells depend on its concentration gradient ? Choose the 1 correct answer

Reminder: Cato, a Burmese cat, has lost interest in play and other activities. His cardiac output is in the normal range, but his heart rate is much higher than normal. His alveolar PO2 is higher than normal, while his alveolar PCO2 is lower than normal, and he is breathing hard all of the time. His arterial PO2 is lower than normal, as is his arterial percent hemoglobin saturation (below 70%). Question: Which diagnoses align with Cato’s symptoms? There are 3 possible answer.
