What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What two forces drive the passive transport of ions across a membrane?
The two forces that drive passive transport of ions across a membrane are concentration gradient and electrochemical gradient. The concentration gradient occurs when ions move from an area of higher concentration to an area of lower concentration, while the electrochemical gradient is established by the combined forces of the ion's concentration gradient and the electrical charge across the membrane.
When the concentration of a substance differs from one area to another this is called concentration?
This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport is the process that requires cellular energy to move a substance against its concentration gradient. This process uses ATP to pump molecules across the cell membrane, creating a concentration gradient where the molecule is more concentrated on one side of the membrane than the other.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What term describes the difference in the concentrations of a substance across a cell's membrane?
The term that describes the difference in concentrations of a substance across a cell's membrane is called the concentration gradient. This gradient drives the movement of substances such as ions or molecules across the membrane through processes like diffusion or active transport to achieve equilibrium.
What two forces drive the passive transport of ions across a membrane?
The two forces that drive passive transport of ions across a membrane are concentration gradient and electrochemical gradient. The concentration gradient occurs when ions move from an area of higher concentration to an area of lower concentration, while the electrochemical gradient is established by the combined forces of the ion's concentration gradient and the electrical charge across the membrane.
When there are different amounts of a substance on either side of the cell membrane an gradient results?
osmosis

This is called a concentration gradient, which represents the difference in concentration of a substance between two locations. The substance will naturally move down the concentration gradient from areas of higher concentration to lower concentration through processes like diffusion or active transport.
Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
What facilitated passive transport across a cell membrane?
concentration gradient
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
