How are simple and facilitated diffusion similar?

How are simple and facilitated diffusion similar?

Simple diffusion and facilitated diffusion are similar in that both involve movement down the concentration gradient. The difference is how the substance gets through the cell membrane.

What characteristic makes facilitated diffusion different from simple diffusion?

Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient.

What characteristic makes facilitated diffusion different from simple diffusion quizlet?

Facilitated diffusion moves molecules against a concentration gradient. Facilitated diffusion requires the input of ATP. Simple diffusion only involves the movement of water across a semipermeable membrane.

What are the characteristics of simple diffusion?

The characteristics of simple diffusion are concentration gradient, particle or molecule size, and permeability of the membrane. The successful simple diffusion is based on the increased diffusion rate and increased surface area of the semi-permeable membrane that increases the mobility rate of solutes.

What are the similarities and differences between facilitated diffusion?

Simple DiffusionFacilitated DiffusionDiffusion TypesYesYesHelps Equalize ConcentrationYes, but through passive transportYes, but through active transportDirection of FlowHigher to lowerHigher to lower

What are the similarities and differences between osmosis and facilitated diffusion?

Osmosis involves the movement of water molecules. Water molecules move from a region of high concentration to a region of low concentration. Facilitated diffusion on the other side involves insoluble compounds such as sugars, amino acids and ions which can pass through a partially permeable membrane.
