BiologyNervous systemA2/A-levelWJEC Created by: rhiannonCreated on: 15-10-13 19:42 What is the typical value for a resting potential? -70mv 1 of 10 Membrane is said to be _________ Polarised 2 of 10 How are Sodium ions and potassium ions passed across the membrane? by active transport via a sodium ion potassium ion pump 3 of 10 Sodium ions are transported ______ of the axon Out 4 of 10 Potassium ions are transported _____ the axon Into 5 of 10 How many sodium ions are pumped out and how many potassium ions are pumped in 3 sodium ions, 2 potassium ions 6 of 10 What does this create? Uneven distribution of charge 7 of 10 Sodium ion channels ________ Close 8 of 10 Potassium ion channels ________ Open to allow potassium ions to diffuse out 9 of 10 Which is more positively charged, outside of the axon or inside? Outside 10 of 10
