Are osmosis and endocytosis passive transports?

Answer 1

It is an active transport,

Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.

Passive transport mechanisms Active Transport mechanisms

• Simple diffusion
• Osmosis
• Facilitated Diffusion

• Simple protein channels
• Gated channels

• Active transport via protein pumps
• Bulk flow mechanisms

• endocytosis

• phagocytosis
• pinocytosis

• exocytosis

The passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.

Answer 2

Osmosis is a passive transport process where water molecules move across a selectively permeable membrane from an area of high water concentration to an area of low water concentration. Endocytosis, on the other hand, is an active transport process where cells engulf large molecules or particles by forming vesicles to bring them into the cell.

Answer 3

Yes. Endocytosis can be facilitated, though.

Answer 4

exocytosis and endocytosis are examples of active transport. They expand energy in order to transfer into and out of a cell.

Answer 5

Endocytosis and exocytosis are two forms of active transport. Diffusion and osmosis are two forms of passive transport.

Answer 6

yes because it moves in and out if a cell

Answer 7

it is an active transport process

Answer 8

no
