1. If a sensory neuron is voltage-clamped at -70 millivolts in normal saline (so all ion channels can work) you would expect to see: a)relatively little current flow, since this is near the resting potential, where the membrane potential is mostly balancing the concentration gradients for the various ions b)a large positive current inward as potassium enters the cell c)a large positive current inward as sodium enters the cell d)a large positive current outward as sodium leaves the cell 2....

17. Which of the following statements are accurate? A. Neurotransmitters can act as ligands. B. Acetylcholine is a neurotransmitter. It can bind to an acetylcholine receptor on the surface of a cell. If this receptor is also a sodium channel, we would call acetylcholine a ligand and its receptor a ligand-gated receptor. C. Neurotransmitters can act as chemical signals between two neurons. D. Diffusion is a type of passive transport and does not require energy. Sodium channels are an example...
