Answer: FALSE
Explanation:
The plasma membrane has both Na –K channels across it walls. They are membrane transport proteins which hydrolyse ATP s for the active transport mechanisms for transport of sodium and potassium ions across the plasma membranes .
Naturally,there are more potassium ion channels than sodium channels in plasma membrane; potassium is also extracellular while sodium is extracellular
Therefore ,when some potassium ions diffused into the Axoplasm, from the extracellular medium;;some potassium ions still move out BACK into the extracellular environments. Not all potassium are restricted from leaving .
This leakage occurs because of more available potassium ions channels than sodium ions, and higher number of available potassium ions
Thus the answer is FALSE
the ratio of diffusion <u>is 3 sodium out to 2 potassium in </u>

Answer:
Las células de su cuerpo usan el oxígeno que respira para obtener energía de los alimentos que ingiere. Este proceso se llama respiración celular. Durante la respiración celular, la célula usa oxígeno para descomponer el azúcar. La descomposición del azúcar produce la energía que su cuerpo necesita.
