The difference between simple diffusion and facilitated diffusion is that facilitated diffusion O requires ATP. requires transporter proteins. does not require ATP. moves materials from a higher to a lower concentration. moves materials from a lower to a higher concentration.
Facilitated diffusion differs from active transport because facilitated diffusion: a. requires energy from ATPb. moves molecules from where they are in lower concentration to higher concentrationc. moves molecules from where they are in higher concentration to lower concentrationd. involves ions & molecules that pass through membrane channels
How does uniport transport (facilitated diffusion) compare with simple diffusion? O Uniport transport is much faster and more specific than simple diffusion O Uniport transport consumes energy but simple diffusion does not O Uniport transport is slower but more specific than simple diffusion Similar to simple diffusion, uniport transport is nonspecific O None of the other are correct
Which of the following statements is correct about passive facilitated diffusion? (select all that apply) V It is a process in which molecules move from a region of lower concentration to one of higher concentration (or up a concentration gradient). O It requires a transport protein. O It requires an expenditure of energy by the cell. O It is a process in which molecules move from a region of higher concentration to a region of lower concentration (or down a concentration gradient). O It involves movement of molecules up a concentration gradient and requires a transport protein.

The O O O Na+/K+-ATPase pump performs Facilitated diffusion Simple diffusion Primary active transport
How is active transport different from simple diffusion? Both active transport and simple diffusion transport molecules against the concentration gradient. In active transport, molecules are moved down the concentration gradient; on the B contrary, molecules to be transported in simple diffusion are moved against the concentration gradient. In active transport, molecules are transported with the aid of transport proteins; on the © other hand, molecules to be transported in simple diffusion do not need transport proteins. In active transport, molecules that are transported does not need metabolic energy; in contrast, molecules transported in simple diffusion need metabolic energy.
