What else can I help you with?
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 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.
Which term describes the difference in the concentration of a substance across a cells membrane?
concentration gradient
What term describes the different in the concentrations of a substance across a cell's membrane?
concentration gradient
A concentration gradient ceases to exist when?
A concentration gradient ceases to exist when there is an equal distribution of a substance across a space or membrane. This equal distribution results in no net movement of the substance from one area to another, causing the concentration gradient to reach equilibrium.
When there are different amounts of a substance on either side of the cell membrane is a what gradient results?
When there are different amounts of a substance on either side of the cell membrane the gradient result is called the concentration gradient. The permeability of the cell membrane will determine which substances can easily pass through the cell causing a change to the concentration gradient.

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.
