I understand membranes and transport, but I do not understand how I can calculate this. I understand regular membrane potential is between -40 to -80 mV. Please help explain the following .
1. If only potassium leakage determined membrane potential, what value would membrane potential have in millivolts?
2. What kind of plasma membrane molecule does phospholipase C act upon? (I understastand it cleaves the glycerophosphate bond)
3. What enzyme is needed to catalyze conversion of arachidonic acid into prostaglandin signal molecule??
4. The proteins that lipid-soluble signals like thyroid hormones must bind to for travel in the blood are called ??? (I understand that transport proteins that are water soluble transport them in the blood)
