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.

Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
Diffusion and Osmosis are passive transport mechanisms meaning they do not require?
They do not require energy, which is often in the form of ATP.
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.
Diffusion and osmosis are forms of?
Both are types of passive transport because they require no energy (ATP) to move molecules.
Why is osmosis an example of passive transport and not active transport?
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
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.
Is osmosis an example of facilitated diffusion or active transport?
No. Facilitated diffusion is an example of passive transport because it does not require the cell to expend energy.
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.
Diffusion and Osmosis are passive transport mechanisms meaning they do not require?
They do not require energy, which is often in the form of ATP.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
Does osmosis require a carrier?
NO. Osmosis( by definition) is the DIFFUSION of water from a high concentration gradient to a low concentration gradient across a semipermeable membrane. As diffusion is a form of passive transport, it doesnt require a carrier
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.

Diffusion and osmosis are forms of?
Both are types of passive transport because they require no energy (ATP) to move molecules.
What two processes transport materials through the semi-permable membrane?
Considering the cell membrane itself, processes include diffusion, osmosis, facilitated diffusion (passive processes that do not require energy) and active transport (an active process that requires energy).
Why is osmosis an example of passive transport and not active transport?
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
