∙ 9y agoBulk flow is a form of passive transport. Diffusion, osmosis, electrodiffusion, current flow, and facilitated transport are all also forms of passive transport.

Contrast active and passive transpot.?
PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.
What are examples of passive transport and active transport?
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
How is active transport different from possive transport?
Active transport need energy from outside to perform a function whereas in passive transport the function is performed on the principle of physics. for example active absorption of minerals by the plant roots require energy from respiration whereas passive absorption is achieved by law of diffusion.
Whats the difference between passive transport and active transport?
Active transport requires energy and Passive transport requires no energy.Passive transport is a process which is carried out along the concentration gradient. For example, if the concentration of water is more outside the cell than inside, water will flow into the cell. Simply put, it is actually diffusion which occurs in passive transport and hence, no energy is required.Active transport, however, is carried out against the concentration gradient and hence requires energy. An example of active transport is the uptake of salt by cells through sodium pump.Active transport requires energy and moves particles up their concentration gradient. Passive transport doesn't require energy and moves particles down their concentration gradient.
What are capillary transport mechanism?
diffusion through the membranes bulk flow transport via vesicles or caveolae
How can active transport differ from passive transport?
Active transport can occur against a diffusion gradient ("uphill flow).
Are osmosis and endocytosis passive transports?
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 mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe 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.

Is diffusiona type of passive transport or active transport?
Passive transport is where materials are transported across a membrane without the use of stored energy. Active transport is where materials are transported across a membrane using ATP, or another source of stored cellular energy. Diffusion is where solutes flow across a membrane in response to a concentration gradient, and requires no energy input to occur. Therefore, diffusion is a form of passive transport.

Is Na K pump active or passive?
In biology, an ion transporter, also called an ion pump, is a transmembrane protein that moves ions across a plasma membrane against their concentration gradient, in contrast to ion channels, where ions go through passive transport.
What are capillary transport mechanism?
diffusion through the membranes bulk flow transport via vesicles or caveolae
What is the difference between active and passive diffusion?
passive diffusion requires absolutely nothing, no energy either, the particles simply flow from a high concentration gradient to a low concentration gradient. Active transport however require carrier proteins to allow the particles through the cell membrane
Why do you call diffusion and osmosis passive transport?
Simply, it is the opposite of active transport. It does not "spend" chemical energy. Since passive transport is diffusion, molecules will move from higher areas of concentrations to lowers areas of concentrations and no outside force is needed (unlike active transport).
