What is true about passive transport?
The concentration gradient is the driving force.
What is true about all passive transports?
The concentration gradient is the driving force.
What is the driving force of the membrane?
The driving force is explained by two factors: voltage gradient and concentration gradient. When there are more ions inside of a cell than outside of a cell, the concentration gradient is pushing the ion to exit the cell. This is simple diffusion. If that ion carries a negative charge then it also wants to exit the cell because the outside environment is slightly more positive.So if you add both voltage gradient and concentration gradient you get the driving force. In the example above both gradients are pushing the ion outside of the cell. Sometimes you can have the gradients going in opposites and then the driving force will be determined on which gradient is stronger.
What is the random movement of molecules and ions down their concentration gradient called?
The random movement of molecules and ions down their concentration gradient (meaning from an area of high concentration to an area of low concentration) is called simple diffusion. Simple diffusion is related to the magnitude of driving force, permeability of the membrane, and surface area.
In order for molecules to move against the concentration gradient?
When you have one concentration (amount) of a molecule, connected to a higher or lower concentration through a permeable membrane (bridge), there is a natural force (heat) pushing the molecules to go from the higher concentration to the lower concentration until both sides have balanced (it is also called diffusion, this process is related to the laws of thermodynamics). Anyway this force the measurement of force for this movement is called the concentration gradient. For a molecule to move against this natural force is to against the concentration gradient, it requires an energy GREATER then that from diffusion or heat to push it. An example would be when there is an opposing electrical force strong enough that may push an electrically charged molecule against its concentration gradient.
What is needed to move particles from areas of low concentration to high concentration?
Because the concentration is going up so much energy is needed to do this. If the cell was going from a high concentration to a low, no energy is needed because it is already at a high concentration and its going lower you wouldn't need any energy to go lower at a high stance
What is the primary driving force of wind?
pressure gradient force
What is the driving force for fluid flow?
pressure gradient is
What are the three main driving forces of air motion?
Pressure Gradient Force Coriolis Force Friction Force Pressure Gradient Force Coriolis Force Friction Force
What is the primary driving force for osmosis?
Osmosis is the movement of water through a semi-permeable membrane. When there are different concentrations on either side, the water moves from the side that has the least concentration of solute to the side with the higher concentration of solute. So a different solute concentration drives osmosis.
What factors contribute to the membrane potential of a cell?
There are many factors that contribute to the membrane potential of a cell. The driving force of ions which are a summation of voltage gradient and concentration gradient are an important one. Also other proteins and amino acids contribute to the cell's membrane potential.
What is the energy of the hydrogen ion gradient created across the inner mitochondrial membrane use 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.
