When two sides of a membrane are in contact with each other, the distribution of ions will alter as a result of the binding of a signal molecule to a ligand-gated ion channel.
<h3>
What is a ligand-gated ion channel?</h3>
Ligand-gated ion channels (LGICs) are membrane proteins that are structurally integral and feature a pore that permits the controlled passage of particular ions across the plasma membrane. The electrochemical gradient for the permeant ions drives the passive ion flux.
When a chemical ligand, such as a neurotransmitter, attaches to the protein, ligand-gated ion channels open. Changes in membrane potential cause voltage channels to open and close. When a receptor physically deforms, as in the case of pressure and touch receptors, mechanically-gated channels open.

Answer:
Explanation:
You cant if the path is crooked then speed wont help but throw you off the track over and over.
La respuesta es 3 ohmios
Resistencia total = (1/12 + 1/4) ⁻¹
= (1/3) ⁻¹
= 3 ohmios
Por ejemplo, dos resistencias, R1 y R2 están en serie, la resistencia combinada es R1 + R2.
Cuando se conecta en paralelo, la resistencia total es el recíproco de (1 / R1 + 1 / R2)
En este caso las resistencias están en paralelo
Espero que esto ayude, que tengas un día bendecido!
