Top 6 what happens during the falling phase of the action potential

The falling phase of the action potential is caused by the inactivation of the sodium channels and the opening of the potassium channels. After approximately 1 msec, the sodium channels inactivate. The channel becomes blocked, preventing ion flow. At the same time, the voltage-gated potassium channels open.

What will occur during the falling phase?

Falling Phase: First, the voltage-gated sodium channels inactivate. Second, the voltage-gated potassium channels open (the delayed-rectifier potassium channels). The driving force pushes potassium out of the cell, causing the membrane potential to become negative againNeuroscience: A Journey Through the Brain – The Action Potentialsites.ualberta.ca › ~neuro › OnlineIntro › NeuronAPAbout Featured Snippets

What causes the falling phase of the action potential select the best answer quizlet?

What causes the falling phase of the action potential? Select the best answer. Voltage-gated sodium channels inactivate soon after opening, halting Na+ inflow, and most voltage-gated potassium channels open, causing a rapid outflow of K+. Both events combine to cause the falling phase of the action potential.Mastering Biology Chp. 37 Part 2 HW Flashcards – Quizletquizlet.com › mastering-biology-chp-37-part-2-hw-flash-cardsAbout Featured Snippets

What happens during the falling phase of the action potential quizlet?

The falling phase of the action potential results from closing sodium channels and opening potassium channels. Unlike sodium gates, potassium gates do not open immediately upon depolarization; it takes about 1 msec for them to open, and stay open as long as the membrane is depolarized.Chapter 4 Flashcards | Quizletquizlet.com › Science › Biology › BiophysicsAbout Featured Snippets
