What is the electrochemical gradient of an ion?
spatial variation of both electrical potential and chemical concentration across a membrane. Both components are often due to ion gradients, particularly proton gradients, and the result can be a type of potential energy available for work in a cell
The movement of ions across cell membranes is an example?
Some ions are prevented from moving down their concentration gradients by ATP-driven pumps. Some ions move from high to low concentration gradients through membrane protein channels, and some ion gates in the membrane can open in response to electrical potential changes.
What is a difference in electric charge called?
The chemical gradient refers to the imbalance of substances across the membrane. The Electrical Gradient refers to the difference of charges between substances on different sides of the Membrane. The Electrochemical Gradient refers to the combination of the previous two gradients. The short answer is MEMBRANE POTENTIAL.
What are the steps in the generation of an action potential?
1. electrical signals are sent through nerves. 2. Travels down axon. 3. k+ +Na+ ions flow down concentration gradients to restore equilibrium.
What is the relations between electrical field and electrical potential?
The electrical field E = - dV/dr, the derivative of the electrical potential, V.
Which unit is used when measuring electrical potential?
The most common unit of electrical potential is the Volt (V)
When the electrical potential in a cell is in action versus a resting state the electrical charge reversal?
Action Potential
Where can find medicaton interactions?
Pharmacology books. (Technically, you find the interactions in the people taking the two drugs, but you may learn about the potential for interactions from the pharmacy.)
What is the voltage at the location of a 0.0001-Coulomb charge that has an electric potential energy of 0.5 joules?
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
What is a electrical current is produced when charges are accelerated by an electrical field to move to a position of potential energy that is?
potential energy
What is the electrical unit of potential difference?
Potential Difference is measured in Volts
What is energy stored due to interactions between objects?
potential energy
