In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
When would active transport be used by a cell?
Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
Which way do molecules move during active transport?
hii friends?? hws life?? i think acitve transport moves molecules throught the speed of light and it needs blood and carbon dioxide to go through this process!!! Good luck people who need this answer bye!!! by: gabriel
What process is used to move proteins against the concentrarion gradient?
this is called active transport, bc it uses energy and goes against the concentration gradient
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.

Active transport is used when molecules are moved across a cell membrane against their concentration gradient, from a low to a high concentration.
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
What is primary active transport?
Primary active transport is defined as utilizing energy in the form of ATP to transport molecules across a membrane against their concentration gradient. This means moving from a low concentration to a high concentration.
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration

How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
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 the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
