What is it called when substances move past the membrane without using energy?
Passive transport is when substances move past the membrane without using any energy.
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
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 substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
What are 2 ways that substances across the cell membrane without using energy?
simple diffusion, facilitated diffusion, and osmosis (water)
Substances that move across a cell membrane without using energy?
by simple diffusion, facilitated diffusion, and osmosis.
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
What is moving materials through a cell membrane without using energy is called?
Passive Transport
Assisted transport of a molecule across the cell membrane without an expenditure of energy is known as?
Any movement of molecules into or out of a cell without the expenditure of energy is called diffusion. If the molecule uses special channels to diffuse through the membrane (again, not expending energy), it is called facilitated diffusion.
What is it called when a molecule moves a membrane through a protein channel without using energy?
passive transport
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!!!
