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.

By what process are bacteria brought into a cell?
Faciliated diffusion
What process permits absorption of glucose into cells?
jamaican bacon
Cells take in oxygen by simple diffusion and glucose by facilitated diffusion Therefore oxygen uptake and glucose uptake will differ from each other in all respects except what?
the need for ATP ANSWER Facilitated diffusion and diffusion do differ in ATP requirments
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
By what process are bacteria brought into a cell?
Faciliated 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.
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 requires energy diffusion fcilitated diffusion osmosis active transport?
b and c active transpot and faciliated
Cells take in oxygen by simple diffusion and glucose by facilitated diffusion Therefore oxygen uptake and glucose uptake will differ from each other in all respects except what?
the need for ATP ANSWER Facilitated diffusion and diffusion do differ in ATP requirments
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
What happens during the process of faciliated diffusion?
Facilitated diffusion is a passive transport process where specific proteins in the cell membrane help larger or charged molecules pass through. These proteins act as channels or carriers, allowing molecules to move down their concentration gradient without requiring energy input from the cell. This process is important for the movement of substances like glucose and ions across the cell membrane.
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 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 do osmosis differ from diffusion?
osmosis is diffusion through a membrane
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.
