- The balance between the chemical and electrical forces pushing potassium through potassium channels and across the membrane is represented by the potassium equilibrium potential.
- At the equilibrium potential of potassium, which is -80mV, there is no net movement of potassium ions.
<h3>At potassium's equilibrium potential, what happens?</h3>
- At equilibrium, the electrical potential gradient across the membrane precisely balances the gradient of K+ concentration.
- There is no net migration of K+ from one side to the other, despite the fact that K+ ions continue to traverse the membrane via channels.
<h3>How does potassium diffuse in order to influence the membrane potential?</h3>
- Potassium ions will flow down their concentration gradient, or towards the exterior of the cell, because the membrane is permeable to them.
- Although the membrane is not permeable to sodium, there is a concentration gradient that favors sodium diffusion in the opposite direction.

Hello, sorry this is a little late.
I believe the correct answer to your question, "an animals long period of inactivity during winter is called what" would be Hibernation.
Hibernation is when some animals (examples would be bears, and wild rabbits) sleep throughout the entire season of winter, when the temperature is too cold for them. They spend time before hibernation usually stocking up food, and creating a warm place for them to stay.
Hope this helps, and have a great day! :)
Answer:
The mechanisms of transport across the cell membrane are as follow: 1- simple diffusion, 2- facilitated diffusion, 3- primary active transport and 4-secondary active transport
Explanation:
The cell membrane is a selectively permeable structure capable of transporting substances by different mechanisms. Simple diffusion is a type of passive transport (i.e. does not require energy) where non-polar molecules (e.g. O2, CO2) pass across the membrane by a process that does not require energy from the cell. Facilitated diffusion is another type of passive transport where larger polar molecules (e.g., glucose and amino acids) pass across the membrane by using specific transmembrane integral proteins. On the other hand, primary active transport is a type of active transport that uses chemical energy (e.g., ATP) to move substances such as metal ions (Na+, K+, Ca2+) across the cell membrane against their concentration gradient. Finally, secondary active transport is another type of active transport where transporter proteins are used to couple the movement of ions (e.g., H+ protons) down their electrochemical gradient to the transport of another ions/solutes against their concentration/ electrochemical gradient.
