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 is the movement of materials across a membrane that requires energy input, typically in the form of ATP. This process allows cells to move molecules against their concentration gradient, ensuring the proper balance of ions and molecules inside and outside the cell.
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.
What are the process in which materials move through a cell membrane?
diffusion and osmosis
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
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 is the movement of materials across a membrane that requires energy input, typically in the form of ATP. This process allows cells to move molecules against their concentration gradient, ensuring the proper balance of ions and molecules inside and outside the cell.
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 do materials get into and out of the cell?
Through proteins in the membrane.
What is it called when an input of energy is required to move materials through a cell membrane?
Active Transport
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 energy free movement of materials through a cell membrane?
Energy-free movement of materials through a cell membrane is called passive transport. This process includes diffusion, osmosis, and facilitated diffusion, where molecules move from an area of high concentration to an area of low concentration without the input of 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.
What is the molecule that requires energy to pass through the cell membrane?
The molecule that requires energy to pass through the cell membrane is typically an ion or a large polar molecule, such as glucose, which moves against its concentration gradient. This process is known as active transport and involves the use of ATP or other energy sources to facilitate the movement of these substances through specific transport proteins in the membrane. Examples include sodium-potassium pumps and glucose transporters.
