What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
How does CO2 cross the cell membrane?
No, carbon dioxide does not need a transport protein to cross the cell membrane. It can pass through a membrane by diffusion.
How do substances get in and out of a cell if they are to big to pass through the cell membrane?
Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.
Movement of water across a cell membrane?
they pass through channels in the cell membrane
What is the process by which materials enter and leave the cell through the cell membrane?
Either active transport, passive transport, or facilitated diffusion
What do transport dos?
Transport proteins help move (or "transport") large molecules that aren't able to pass through a cell's membrane, through said cell membrane through means of diffusion.
Can Hydrogen peroxide pass through a cell membrane?
yes, H2O2 passes through cell membrane through passive transport.
Function of the cell membrane of a cell?
The transport of molecules into and out of the cell through osmosis and diffusion
When a cell uses energy to transport a particle through the cell membrane to an of higher concentration the cell is using?
Active transport
These structure are passageways from the nucleus that transport proteins through the cell?
cell membrane
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.

The movement of materials through a cell membrane without using the cells energy?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
What transport may need to use energy to pass through cell membrane?
active transport
What is an example of active transport through a cell membrane?
Osmosis. Osmosis is the diffusion of water through a selectively permeable membrane. I'm assuming you mean active transport of plasma into a red blood cell.
