What is diffusion a natural movement of molecules from?
in the normal diffusion the substance move from the area of greater concentration to that of lower concentration. .... but i never know what do we mean be "faciliated" plz specify
What is one example of a substance using faciliated transport?
fatty acids membranes
What requires energy diffusion fcilitated diffusion osmosis active transport?
Active transport requires energy, typically in the form of ATP, to move molecules across a cell membrane against their concentration gradient. Facilitated diffusion, while it still uses membrane proteins to transport molecules, does not require energy as it follows the concentration gradient. Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, also not requiring energy.
What type of transport requires energy to move molecules from an area with low concentration to an area of high concentration?
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Vitamin c is soluble in water and vitamin d is lipid soluble. how does the structure of the cell membrane determine the route taken by each vitamin?
Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion. Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.
By what process are bacteria brought into a cell?
Bacteria can enter a cell through a process called phagocytosis, where the cell engulfs the bacteria using its cell membrane. Alternatively, some bacteria can invade cells by injecting proteins that manipulate the host cell machinery to gain entry.
How is faciliated transport similar to simple diffusion?
Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.
Does faciliated diffusion require energy?
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
What type of transport is faciliated diffusion?
Neither of these require energy. Diffusion occurs naturally when a higher concentration of a substance exists on one side of a membrane than the other; molecules will enter into the area of lesser concentration until there is an equilibrium on both sides. Active transport requires the energy of the cell.

How does faciliated diffusion differ from simple diffusion?
Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.
How does the structure of the plasma membrane determines the route taken by vitamin C and vitamin D?
Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion. Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.
What is normatic diffusion in human resource management industries?
I think someone meant to say "nomadic" diffusion which is part of the Law of Diffusion and innovation in anthropology and geography.
Theory that explains diffusion?
your meant to answer me thats why i asked stoppid website
What process permits absorption of glucose into cells?
The process that permits absorption of glucose into cells is called facilitated diffusion. Glucose is transported across cell membranes with the help of glucose transport proteins, such as GLUT-1 and GLUT-4. These proteins allow glucose to move down its concentration gradient and into the cells where it can be used for energy production.
In facilitated diffusion which process does not require energy?
Simple and facilitated diffusion are a part of passive transport. This refers to the movement of molecules, atoms and ions across the cell membrane. In both of these processes, molecules move from areas of high concentration to areas of lower concentration because equilibrium is trying to be maintained in living organisms. Simple diffusion just happens randomly and without any aides. Facilitated diffusion uses proteins in the cell membrane to guide polar molecules and ions in and out of the membrane (always to areas of lower concentration) and DOES NOT require ENERGY.Only active diffusion requires energy.
What is one example of a substance using faciliated transport?
