Problem:
How much energy is needed for the Na/K pump to move 3 Na out and 2 K in when
Nai (Na inside)= 9.2mM, Nao (outside)= 115, Ki (K inside)= 135mM and Ko (K outside)= 3mM?
Include the effects of membrane potential; it will have to be calculated based on the given ion
concentrations and PNa/Pk of 0.013.

  • Marine animal salt water transport process from blood into gland

    And, in fact, the same transporter, called the Na+/K+ ATPase, does both jobs. It uses the energy from the hydrolysis of ATP to actively transport 3 Na+ ions out of the cell for each 2 K+ ions pumped into the cell.

  • Action Potential and Ion Regulation

    Na concentration is greater outside the cell and K concentration is greater inside the cell. This ion exchange includes 3 Na pumped out of the cell and 2 K pumped into the cell. The K channel allows K ions to diffuse out of the cell.

  • Resting membrane potential maintenance

    Also, the membrane is way more impermeable to K+ ions than to Na+ ions.

  • Electrical Properties of an Individual Neuron and Implanting Electrodes into the Brains of Prisioners

    These channels can be voltage-gated, as in a change in membrane potential will trigger their activation (and deactivation), or ATP-dependent, such as the Na/K ATP pump.

  • Goldman equation

    In a very simple sense, the cell is a container full of water and dissolved ions -- Na and K are the ones we're primarily concerned with. There is a Sodium-Potassium pump that will pump potassium into the cell and sodium outside.

  • Aldosterone

    This translates into an adequate blood volume able to carry efficiently nutrients to the cell (like lipids and sugars supply necessary energy source and basic elements for the formation of hormones), and a "normal" blood pressure.

  • Nervous System

    (4) ____ proteins that span the membrane pump sodium and potassium ions against their concentration gradients across it by using energy stored in ATP.

  • Ionic and Covalent Bonding

    Property Explanation Melting point and boiling point The melting and boiling points of ionic compounds are high because a large amount of thermal energy is required to seperate the ions which are bound by strong electrical forces.
