What is one way that materials pass through the cell membrane that requires no energy from the cell?

A process that requires no energy input is passive.
One passive process used by materials crossing a cell membrane is diffusion.
Examples:
- oxygen diffuses through the phospholipid bilayer into a cell that is respiring aerobically.
- carbon dioxide diffuses out of cells through the phospholipid bilayer.
Facilitated diffusion (diffusion through transport proteins: channel and carrier proteins) is a form of diffusion, and so it is also passive.
Another passive process is osmosis. This is the process by which water crosses a cell membrane either into or out of the cell, but always into the solution that has the higher total concentration of solutes.

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.
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 movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
When an input of energy is required to move material through a cell membrane what transport takes place?
Active transport requires energy to move substances across a cell membrane against their gradient.
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.
Active transport involves what?
Active Transport requires first of all Energy which is obtained from respiration and secondly a selectively permeable membrane through which movement of materials can take place.
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 two processes transport materials through the semi-permable membrane?
Considering the cell membrane itself, processes include diffusion, osmosis, facilitated diffusion (passive processes that do not require energy) and active transport (an active process that requires energy).
How is active transportation different from passive transportation?
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.

What is moving materials through a cell membrane without using energy is called?
Passive Transport
How do you use active transport in sentence?
it is the movement of materials through cell membrane using energy
What is the movement of material through a cell membrane that requires energy?
Active transport. The sodium-potassium pump is an example of this.
