Question 18 1 pts Imagine you are a cell biologist who is studying the properties of a transmembrane protein. You have successfully isolated it and can synthesize membranes with this protein and no others. You have observed that the protein has the following properties: (1) The permeability to Ca2+ increases when the membrane potential is exposed to an action potential. (2) These changes in permeability do not vary with the concentration of ATP. What can you safely conclude about the transmembrane protein from these observations? It uses secondary active transport to move Ca2+ across the membrane. It could function in the activation of smooth muscle. It could play a role in the release of neurotransmitter at a synapse. 00
