What is one example of a substance using faciliated transport?
fatty acids membranes
What is an example of active transport using physiological processes in the human body?
diffusion occurs naturally facilitated diffusion and active transport need energy
Large proteins can be secreted from the cell using the process of?
Exocytosis
Why is energy required for facilitated diffusion?
because those that can't get through the membrane by themselves can get help. transport proteins give them a ride through the membrane. different transport proteins make it easier for certain molecules to get through the membrane without cell using energy
What is the process which cells use to bring in or take out substances using energy?
You are probably thinking of facilitated diffusion but endocytosis also used energy. The difference is in the size of the item that is being taken in. Endocytosis involves larger items while facilitated diffusion involves very small items like ions.
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 is a passive transport using carrier protiens?
Facilitated diffusion
What is one example of a substance using faciliated transport?
fatty acids membranes
Cell must expend energy to transport substances using?
Facilitated diffusion.
What cell must expend energy to transport substances using?
Facilitated diffusion
Substances that move across a cell membrane without using energy?
by simple diffusion, facilitated diffusion, and osmosis.
What is an example of active transport using physiological processes in the human body?
diffusion occurs naturally facilitated diffusion and active transport need 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.
Large proteins can be secreted from the cell using the process of?
Exocytosis
Movement of a substance across a cell membrane using chemical energy occurs during?
active transport
What Name one type of substance that is taken into a root hair cell using active transport?
ion
How do substances move through cell membrane?
Active transport - When the cell uses energy to move the substance across a partially permeable membrane. Usually done when What_are_three_ways_for_materials_to_move_in_and_out_of_cellsagainst a concentration gradient or water potential.Diffusion/Passive transport - When the substance moves across a partially permeable membrane down a concentration gradient or What_are_three_ways_for_materials_to_move_in_and_out_of_cellspotential. (Method takes no energy).Osmosis - The movement of water down a water potential across a partially permeable membrane. (This uses no energy).
