The sodium-potassium pump does not run out of ions since ion exchange is essential for the action potential to take place and to maintain homeostasis.
The cell has variable concentrations of different substances compared to the environment that surrounds it, with significant differences with sodium and potassium.
- The main function of the sodium-potassium pump is to maintain homeostasis of the intracellular medium, controlling the concentrations of these two ions.
- In order to carry out the adequate exchange of sodium and potassium ions in the extra and intracellular medium, the cells need an active transport process that is carried out thanks to the sodium potassium pump.
- This process is needed for the maintenance and functioning of cells, and it is essential for the action potential to be executed, necessary for the transmission of electrical impulses from neuron to neuron.
Therefore, we can conclude that the sodium potassium pump produces an exchange of potassium ions for sodium ions which keeps the cellular system functioning properly.

Answer:
E = 1.5 x 10⁻¹⁷ J
Explanation:
The Rydberg equation for electronic transitions in the hydrogen atom is
1//λ = Rh x ( 1/n₁² - 1/n₂²)
where
Rh : Rydberg´s constant 1.09737 x 10 ⁷ m⁻¹
n₁ : Intial energy Level
n₂ : Final energy Level
But for non-hydrogen one electron ions such as He+ and Li2+ ²⁺ , the equation is similar but multiplied by Z²:
1/ λ = Rh Z² x ( 1/n₁² - 1/n₂²)
I will work this problem by fist calculating 1/λ and then use the equation E= hc/λ where
h : Planck´s constant 6.626 x 10 ⁻³⁴ J s
c : Speed of light 3 x 10 ⁸
1/ λ = 1.09737 x 10 ⁷ m⁻¹ ( 3² ) x ( 1/1² - 1/2² )
1/ λ = 7.4 x 10⁷ m⁻¹
E = 6.626 x 10 ⁻³⁴ J s x 3 x 10^8 m/s x 7.4 x 10⁷ m⁻¹
E = 1.5 x 10⁻¹⁷ J
Answer:
I think it is true, but I am not to sure.
Answer:
2.4 %
Explanation:
.15 mole * ( 23 + 16 + 1) gm / mole = 6 gm in solution
250 cm^3 of water solvent weighs 250 gm
6 gm / 250 gm = 2.4 %
For the first one you have to be very close to smell it, when lit the aroma fills the class because there is no ventilation and how there is no way for the gas to leave the room
