The action potential spreads through an axon by Group of answer choices depolarizing adjacent membrane to threshold, triggering
Step2247 [10]

The action potential spreads through an axon by depolarizing adjacent membrane to threshold.

  • K+ departs the cell after Na+, which enters the cell first. Ions can move freely across the axon membrane because of the difference during the action potential.
  • Because sodium contains a positive charge, the neuron becomes more positive and depolarized. Potassium channels take longer to open. As soon as the cell does open, K+ rushes out, reversing the depolarization known as repolarization.
  • Sodium channels close during the peak of the action potential when potassium leaves the cell. When potassium ions are effluxed, the membrane potential is lowered or the cell becomes hyperpolarized.
  • Outside of the cell, the concentration of Na+ is greater than inside the cell. while the concentration of K+ is  is greater inside the cell than outside.

How many different codons can code for the amino acid tryptophan (Trp)?
