Active vs Passive Transport

Cells have two ways in which they can move things in and out through the cell membrane. These two ways are...

• Endocytosis and Exocytosis Transport

• Active and Passive Transport

• Diffusion and Osmosis

• Pushing and Pulling

Passive transport is different from Active transport in that...

• It requires no energy

• it requires energy

• Flows from High concentration to Low concentration

• Flows from Low concentration to High concentration

The three types of passive transport are

• Osmosis

• Diffusion

• Protein Pumps

• Facilitated Diffusion

Active transport...

• Requires energy and flows from High to Low concentration

• Requires energy and flows from Low to High Concentration

• Does not requires energy

• Does not require energy and there is no movement

Osmosis (passive) is the movement of

• Small Particles

• Larger particles through protein

• Water through proteins

• Gas

Diffusion is the movement of

• Large particles through proteins in the membrane

• Small particles or gasses through the membrane

• Water through proteins in the membrane

• small particles through proteins in the membrane using energy

Facilitated (helped) Diffusion is the movement of

• Small particles through the membrane

• Larger particles through proteins in the membrane requiring no energy

• Water through proteins in the membrane

• Small particles through proteins in the membrane using energy

The following picture is showing which form of active transport where the cell engulfs (eats) material (solid/liquid) by forming a vesicle (transport structure).

• Protein Pumps

• Exocytosis

• Endocytosis

• Facilitated Diffusion

The following pictures is showing which form of active transport where the cell expels (releases) waste.

• Endocytosis

• Protein Pumps

• Exocytosis

• Diffusion

Protein Pumps are a form of active transport that...

• requires energy (ATP) to move particles against (up) the concentration gradient (natural flow) Low to high.

• requires energy (ATP) to move particles with (down) the concentration gradient (natural flow) high to low.

• does not require energy, moving particles from high to low concentration

• does not require energy, moving particles from low to high concentration.
