What else can I help you with?
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.
What is the diffusion of particles without the use of energy?
Osmosis is an example of movement of particles from an area without the need of additional energy. If a state is not in equilibrium particles can move from one area to another without additional energy.
The movement of substances through a cell membrane without the use of cell energy?
Passive transport using osmosis and diffusion. Osmosis only applies to the movement of water down a concentration gradient across a selectively permeable membrane. DOH!!!
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
Is the movement of molecules across a membrane down the concentration gradient a passive or active process?
The movement of molecules across a membrane down the concentration gradient is a passive process.
What is the movement of the chest that brings air into lungs and takes out waste gases called?
The movement of the chest that brings air into the lungs is called inhalation, and it is facilitated by the contraction of the diaphragm and intercostal muscles. Exhalation is the process of removing waste gases from the lungs, which is typically a passive process where the diaphragm and intercostal muscles relax.
If the movement of molecules requires no energy?
it is called passive transport
Does passive or active processes account for the movement of fats and respiratory gases through the plasma membrane?
Passive processes, such as simple diffusion and facilitated diffusion, account for the movement of fats and respiratory gases through the plasma membrane. These processes do not require energy input and rely on the concentration gradient to drive the movement of molecules across the membrane.
What is the movement of gases in and out of a cell called?
When a gas moves in and out of a cell it is called diffusion.
What is the name for the movement of gases at the surface of an alveolus?
this is called respiration
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.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
What movement of gas molecules from a region of higher concentration to a region of lower concentration?
osmosis is the passive movement of a substance from a place where its concentration is higher, to another where its concentration is lower. This applies to gases, I guess
What name is given to the movement of gases?
The movement of gases is called diffusion. It is the process by which gases like oxygen and carbon dioxide move across a concentration gradient to reach equilibrium in a space.
What is the movement of sucrose molecules called?
The movement of sucrose molecules is called diffusion, which is the process of molecules spreading out from an area of high concentration to an area of low concentration. This movement occurs until equilibrium is reached.
What does PIR stand for in alarms?
Passive Infra Red. Units that detect movement.
