Describe the movement of Na+ and K+ when a Na+/K+ pump is working. Make sure to indicate how many molecules are being transported, which direction they are moving (into or out of the cell), and whether they are moving via active or passive transport.
Homework Answers
The moving of Na+ and K+ ions across the cell plasma membrane is an active transport, and it uses ATP for the movement of ions across the membrane.
The sodium-potassium pump is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continually pumps sodium ions out of the cell and potassium ions into the cell, powered by ATP. For each ATP that is broken down, it moves 3 sodium ions out and 2 potassium ions in. As the cell is depleted of sodium, this creates an electrical gradient and a concentration gradient, both of which are put to use for many tasks.

Roles of the Na+/ K+ pump 1. Maintain the Nat/K+ concentration gradicnt across the plasma membrane. (That's obvious) 2. It plays a role in maintaining the resting membrane potential. Why? 3. The steep electrochemical gradient of Na+ is used in "coupled active transport" (coupled pumps). If the Nat/K+ pump stops, then these Na+ coupled transport mechanisms will also eventually stop. Explain The apical surface of the epithelial cells that line the lumen of the gut contains a symport that used...

1. Animal cells have a Na,K pump that couples the energy of ATP hydrolysis to transport 3 Na ions out of the cell and 2 K ions into the cell. Inside astrocytes, the concentration of Na is 20 mM and the concentration of K is 130 mM. The extracellular concentrations of Na and K are 145 mM and 5 mM, respectively. Calculate the energy required for the transport of Na and K , with this stoichiometry; assume that the cell...

How can dissolved materials be moved from the outside to the inside of a cell when the inside concentration of the material is higher than the outside concentration? a. Molecules can be moved into a cell against their concentration gradient if that transport is coupled with osmotic transport of water into the cell. b. Substances can be moved against a concentration gradient by pumps that do work using the energy provided by ATP hydrolysis. c. Some channels are capable of...

Draw/Describe how the Na+/K+ pump functions. Use specific details, present steps in chronological order using a cause/effect - if/then approach: “if ___(cause) occurs, then ____(effect) happens). Include concentrations gradients (before and after), membrane proteins, direction of molecule flow (into/out of, from high to low/low to high, up/down or with/against the gradient). Include any additional details you feel are relevant. What type of transport is this? What is the overall role of the pump?
