Describe a form of active transport similar to the work of carrier proteins?
Molecules are moved through the cell membrane by 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
Active transport is the process of what?
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
During active transport substances move from regions of what?
in active transport, where do molecules always go
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.
How are the sodium ions moved out of the neuron?
by "sodium pump", a process involving active transport
Which molecules are moved into a cell against their concentration gradient the process is?
Always active transport when something is moved against it's concentration gradient. Excepting, perhaps cotrasport, though many biologists see active transport here also.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport
Describe several ways molecules are moved across a plasma membrane?
Diffusion, osmosis, facilitated transport and active transport- which requires energy to work.
What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Materials can be moved from a low concentration to a high concentration through?
The process that is able to move materials from low concentration to high concentration is called active transport. Active transport uses energy while diffusion does not use energy.
