Na and Cl flows inside, K and Ca flows outside K and Ca flows inside, Na and Cl flows outside Na and K flows inside, Ca and Cl flows outside Na and Ca flows inside, K and Cl flows outside
Part 1: If a gated channel (not a pump) is specific for potassium ions and based on what you know about concentration gradients, when will the potassium ions move through the channel? a) Is gated channel transport using energy (ATP)? Part 2: Why does the sodium - potassium pump need to use energy (ATP)? a) Define active transport in your own words.
A cell has a membrane potential of -100 mV (more negative inside than outside) and has 1,000 times more calcium ions outside the cell than inside. Which best describes a mechanism by which Ca2+ enters this cell? facilitated diffusion of Ca2+ into the cell down its electrochemical gradient movement of Ca2+ into the cell through an ion channel down its concentration gradient passive diffusion of Ca2+ into the cell down its electrochemical gradient cotransport of Ca2+ into the cell with Cl- movement of Ca2+ into the cell through a carrier protein down its electrical gradient I know that the answer is 1 but please explain why. Thank you.
Given two cells that are identical in all ways except that extracellular concentration of Na+ ions is grater for cell A differ from that that in cell B if stimuli of identical strength were applied to each
DRAW IT Three of the events described in the figure are ion flow; change in membrane potential; andopening, closing, or inactivation of channels. Use these events to draw a simple circuit diagram for thepositive feedback that underlies the rising phase of the action potential.
What is the free energy change for the transport of calcium ions (Ca++) across a membrane from a region (left) where the concentration is 50 micromolar to a region (right) where the concentration is 50 micromolar? A membrane potential of 60 mV exists across the membrane where the right side is more negative than the left side. The temperature is 25 C.
How is the cell membrane like a battery? Membrane potential (think of the properties of a battery) Resting membrane potential Na+ and K+ ions -> -70 mV Na+/K+ pump Stored energy for work

TTX blocks K channel, and TEA blocks Na Channels. No change in the equilibrium potentail. TTX blocks Na channel and TEA blocks K Channels. The equilibrium potentials become less positive TTX blocks Na channel and TEA blocks K Channels. The equilibrium potential becomes more positive for both TTX blocks Na channel and TEA blocks K Channels. No change in the equilibrium potentail. TTX and TEA blocks Na channel. No change in the equilibrium potentail.
At the membrane of an axón, the action potential is -60 mV for K+ ions. Calculate the external and internal concentration ratios.
Watch this video (http://openstaxcollege.org/l/summation) to learn about summation. The process of converting electrical signals to chemical signals and back requires subtle changes that can result in transient increases or decreases in membrane voltage. To cause a lasting change in the target cell, multiple signals are usually added together, or summated. Does spatial summation have to happen all at once, or can the separate signals arrive on the postsynaptic neuron at slightly different times? Explain your answer.
