What requires energy diffusion fcilitated diffusion osmosis active transport?
b and c active transpot and faciliated
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
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.
What is one example of a substance using faciliated transport?
fatty acids membranes
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.
By what process are bacteria brought into a cell?
Faciliated diffusion
Does faciliated diffusion require energy?
Yes, faciliated diffusion is when a cell uses energy to maintain homeostasis, but regular diffusion is when homeostasis occurs without using energy.
What process permits absorption of glucose into cells?
jamaican bacon
What requires energy diffusion fcilitated diffusion osmosis active transport?
b and c active transpot and faciliated
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 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.
Which organelle is involved in osmosis and diffusion?
plasma membrane
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.

What is faciliated diffusion?
movement of specific molecules across cell membranes through protein channels
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.
