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.
In diffiusion movement of particles across a membrane is drven by what differences?
In diffusion, the movement of particles across a membrane is driven by an electrochemical gradient-the ion's concentration gradient and the membrane potential. Substances will passively diffuse down their concentration gradient to where they are less concentrated. Since the inside of a cell is negative compared to its outside, the membrane potential will drive the passive transport of cations into the cell and anions out of the cell due to electrostatic attractions.
What is the energy of hydrogen ion gradient created across the inner mitochondrial membrane used to make?
The hydrogen falls down its electrochemical gradient, from an area of high concentration to an area of lower concentration, through the ATP synthase and provides the force to power this synthase and synthesize ATP.
Where do ions diffuse across membrane to specific ion channels?
down their electrochemical gradients.
What facilities passive transport across a cell membrane?
concentration gradient.

Is concentration gradient a form of potential energy?
w hen solute concentrations differ on the two sides of a membrane
Ions diffuse across membranes down their what?
Its an active transport and use sodium channel generally _____ Diffusion is itself a pathway of travel across a cell membrane. Diffusion can be "simple diffusion" which is simply an ion moving across the membrane anywhere, or "fascilitated diffusion", where an ion moves across the membrane in a specific channel. Either way, diffusion involves the movement of that ion along its concentration gradient and requires no energy. Active transport is not the same as diffusion. Active transport requires energy.
Why is a sodium potassium pump important in organisims?
Na/K ATPase is essential in maintaining the electrochemical gradient across the cell membrane. The electrochemical gradient generated by transporting Sodium out and Potassium in is used in secondary active transport, maintanence of osmotic balance, and most importantly, action potential generation and propagation in muscle and nerve cells.

In photosynthesis an H plus ion gradient froms across what?
across the thylakoid membrane
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What facilitated passive transport across a cell membrane?
concentration gradient
What facilities passive transport across a cell membrane?
concentration gradient.
