Glucose is commonly transported across cell membranes using facilitated transport. Glucose transporter proteins help facilitate the movement of glucose molecules down their concentration gradient into cells without requiring energy input.
Entry of CO2 in the leaves during photosynthesis and its exit during night.
Absorption of water by root hairs is another example of facilitated diffusion.

What is one example of a substance using faciliated transport?
fatty acids membranes
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
How is facilitated diffusion different from avtive transport?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following the concentration gradient and requiring no energy input. Active transport, on the other hand, is an energy-requiring process that moves molecules against their concentration gradient using ATP or an electrochemical gradient.
The movement of materials through a cell membrane without using the cells energy?
Passive transport is the movement of materials across a cell membrane without the cell using energy. This can include processes like diffusion, osmosis, and facilitated diffusion.
What is an example of active transport using physiological processes in the human body?
Absorption of nutrients in the intestines is an example of active transport in the human body. Nutrients like glucose and amino acids are transported from the intestinal lumen into the bloodstream against their concentration gradient by using energy from ATP through active transport processes involving carrier proteins. This allows the body to absorb essential nutrients efficiently for use in various metabolic processes.
What does facilitated diffusion do in a cell?
It allows for the flow of substances which are normally too large to pass through the cell membrane. Like active transport, it accomplishes this using channel proteins coded for each specific substance (sugar, for example). Unlike active transport, facilitated diffusion only works WITH the osmotic pressure gradient, not against.

Substances that move across a cell membrane without using energy?
Passive transport is the movement of substances across a cell membrane without the use of energy. This process includes simple diffusion, facilitated diffusion, and osmosis. These mechanisms rely on the concentration gradient to drive the movement of molecules.
What is the difference between facilitated diffusion with help of the carrier molecule and active transport with help of a transport protein?
Facilitated diffusion with a carrier molecule allows molecules to passively move down their concentration gradient without energy input, using a specific carrier protein. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient using a specific transport protein.
What 2 transport processes use carrier proteins?
Two transport processes that use carrier proteins are facilitated diffusion and active transport. In facilitated diffusion, carrier proteins help move molecules across the cell membrane down their concentration gradient, while in active transport, carrier proteins help move molecules against their concentration gradient by using energy.
Is facilitated diffusion type of active transport?
No, facilitated diffusion is a type of passive transport in which molecules move across a cell membrane with the help of specific transport proteins. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
How is facilitated diffusion different from avtive transport?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following the concentration gradient and requiring no energy input. Active transport, on the other hand, is an energy-requiring process that moves molecules against their concentration gradient using ATP or an electrochemical gradient.
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
The movement of materials through a cell membrane without using the cells energy?
Passive transport is the movement of materials across a cell membrane without the cell using energy. This can include processes like diffusion, osmosis, and facilitated diffusion.
