an example of a passive transport process is?
538059
Another big example of passive transport is osmosis. This is a water specific process. Usually, cells are in an environment where there is one concentration of ions outside and one inside. Because concentrations like to be the same, the cell can pump ions in an out to stay alive.

Diffusion and osmosis do not require any energy, so both are examples of passive transport. To move particles against the concentration gradient (low to high concentration) would require energy. Any transport that requires energy is called active transport.

Explanation: osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane, so little energy is required to carry out this process, thus it is a form or passive transport.

It could be the movement of water (osmosis), or other "stuff" (diffusion). If a cell is placed in an isotonic solution, that means the amount of stuff inside the cell and outside the cell is equal. ... No diffusion or osmosis will occur. That's because passive transport mechanisms seek to reach equilibrium.

Diffusion relies on random kinetic movement to spread molecules from high- to low-concentration areas. Conversely, active transport exports or imports particles against the concentration gradient -- from an area of low concentration to high.

There are two classes of membrane transport proteins—carriers and channels. Both form continuous protein pathways across the lipid bilayer. Whereas transport by carriers can be either active or passive, solute flow through channel proteins is always passive.

Simple diffusion is the passive movement of solute from a high concentration to a lower concentration until the concentration of the solute is uniform throughout and reaches equilibrium. ... Simple diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy.

Diffusion across a cell membrane is a type of passive transport, or transport across the cell membrane that does not require energy. ... Therefore, simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules from a higher concentration to a lower concentration.

Osmosis. Osmosis is a term describing the movement of water from across a selectively permeable membrane as a result of a concentration gradient. I.e. it is a special type of diffusion concerned only with water. ... Osmosis is also a form of passive transport, as it does not require the expense of energy.

Advection and Diffusion. Transport processes in the environment may be divided into two categories: advection and diffusion. Advection refers to transport with the mean fluid flow. ... In contrast, diffusion refers to the transport of compounds through the action of random motions.

Active transport the molecules move from a lower concentration to a higher concentration. Passive transport the molecules move from a higher concentration to the lower concentration.

Active Transport. Active Transport is the term used to describe the processes of moving materials through the cell membrane that requires the use of energy. There are three main types of Active Transport: The Sodium-Potassium pump, Exocytosis, and Endocytosis.

Types of passive transport include simple diffusion, osmosis, and facilitated diffusion. Active transport requires energy from the cell. ... Types of active transport include ion pumps, such as the sodium-potassium pump, and vesicle transport, which includes endocytosis and exocytosis.

Active transport is the movement of a substance across a membrane against its concentration gradient. ... Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport.

Requires energy; diffusion and osmosis are types of passive transport. ... Passive transport moves materials through a cell membrane without using energy while active transport uses energy to move materials through a cell membrane. They are both moving materials through the cell membrane.
