1.	Which of the following is not true regarding resting potential?(a) There is a potential difference across the plasma membrane(b) The potential difference is maintained by the Na-K pump(c) The outer surface of the membrane is negatively charged(d) The axonal membrane is polarizedThis question was posed to me in an interview for internship.I want to ask this question from Neuron-2 topic in chapter Neural Control and Coordination of Biology – Class 11
Answer» Correct answer is (c) The outer SURFACE of the membrane is negatively charged To explain I would say: The AXONAL membrane is positively charged on the outer surface and negatively charged on the inner surface. This MAKES the membrane POLARIZED. The potential DIFFERENCE is maintained by the Na-K pump.
