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?
It's called passive transport for a cell's membrane. (I checked with my science teacher)
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.

What cell must expend energy to transport substances using?

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?
The most essential difference is that one is active (uses energy) and one is passive (doesn't require energy). Take note whenever you see the word 'active' in this context- it denotes that energy is required for it to occur, usually against the concentration gradient. Facilitated diffusion is just another passive process by which molecules move from an area of high concentration to low concentration. Note that this requires no energy to occur, except it differs from diffusion in that a carrier molecule is required (usually because the molecule is too large to freely cross the plasma membrane)
How do facilitated diffusion and active transport compare and contrast in terms of their mechanisms of transport across the cell membrane?
Facilitated diffusion and active transport are both ways that substances move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels to help substances passively move from areas of high concentration to low concentration, while active transport requires energy to move substances against their concentration gradient using protein pumps.
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?
Facilitated diffusion is passive transport as no energy is used, and a protein channel is all that's required. After that it is simple diffusion down a concentration gradient. Anything with the word diffusion in it is passive transport. Diffusion is just the principle of passive transport.
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.
