Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
Is facilitated diffusion is an active transport?
The name itself indicates there difference. Diffusion occurs without any other active participant/free flow diffusion is called Transport diffusion. Diffusion occurs with help of other active participant is called Facilitate Diffusion
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
Facilitated diffusion and active transport?
Facilitated diffusion is the passive transport of molecules across a membrane with the help of transport proteins. This process occurs down the concentration gradient and does not require energy. In contrast, active transport requires energy to move molecules against their concentration gradient through specific transport proteins.
What are the three ways that things move in and out of the cell?
Things can move in and out of a cell through passive diffusion, facilitated diffusion, and active transport. Passive diffusion involves movement down a concentration gradient without the need for energy input, while facilitated diffusion involves the use of transport proteins. Active transport requires energy input to move molecules against their concentration gradient.

Differences between active transport and facilitated diffusion?
Active transport requires energy in the form of ATP to move molecules against their concentration gradient, while facilitated diffusion uses carrier proteins to move molecules down their concentration gradient without requiring energy. Active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
Facilitated diffusion do molecules move down concentration gradient or against a concentration gradient?
Diffusion is a passive process that does not require energy. Under experimental conditions it can be observed that both living and dead cells exhibit diffusion.
What drives Facilitated diffusion?
Facilitated diffusion is a passive process whereby a molecule is "carried" across a semi-permeable membrane by a channel or protein carrier. Like diffusion, this process requires no energy, however, since passive diffusion can drive movement against a concentration gradient it is not really diffusion.

Why do solutes move across a lipid bilayer?
Solutes can move across a lipid bilayer through passive diffusion, facilitated diffusion, or active transport. Passive diffusion occurs when solutes move down their concentration gradient, facilitated diffusion involves the use of transport proteins, and active transport requires energy to move solutes against their concentration gradient.

Things can move in and out of a cell through passive diffusion, facilitated diffusion, and active transport. Passive diffusion involves movement down a concentration gradient without the need for energy input, while facilitated diffusion involves the use of transport proteins. Active transport requires energy input to move molecules against their concentration gradient.
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
How do most molecules cross the cell membrane?
Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
