What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What is the name of cellular process in which materials are moved across a membrane from an area of low concentration to an area of high concentration?
active transport
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.
How does the cell membrane pass materials?
The cell membrane passes materials through a process called passive or active transport. Passive transport uses the natural movement of molecules from an area of high concentration to low concentration, while active transport uses energy to move molecules against their concentration gradient. Additionally, the cell membrane contains specific transport proteins that facilitate the movement of molecules in and out of the cell.
How do small molecules get through the cell membrane against a concentration?
How do small molecules get through a cell membrane
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
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
Is the process in which molecules move across a 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
What is the function of active transport moving small molecules and ions across cell membrane?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What helps to allow materials to cross the plasma membrane?
Materials cross the plasma membrane through processes such as simple diffusion, facilitated diffusion, and active transport. These processes involve the movement of substances across the lipid bilayer of the membrane with the help of transport proteins or by utilizing energy to move against a concentration gradient.
How is passive transport from active transport?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
