it dosent needs energy to be carried out
Diffusion
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
Yes, passive transport is a non-energy requiring process because it does not require energy input from the cell. It relies on the natural movement of molecules down their concentration gradient. Examples of passive transport include simple diffusion, facilitated diffusion, and osmosis.
Normal exhalation is a passive process because it does not require active muscle contraction. Instead, it relies on the relaxation of the diaphragm and intercostal muscles, allowing the lungs to passively recoil and expel air. This passive process is driven by the elastic properties of the lungs and chest wall.
passive transport
It results in tissue death which is what necrosis means.
There is no such thing... Do you avascular necrosis?
Tumor Necrosis Factor or TNF, is a cytokine which is involved in the inflammatory process. Cytokines are chemical substances which deliver messages between cells in the body.
Affected with necrosis; as, necrotic tissue; characterized by, or producing, necrosis; as, a necrotic process.
Yes, passive diffusion is a spontaneous process.
death of tissue
I guess any subject that is not actively involved in the process, but it still plays an important part. For example, you have a wall and two cars hitting the wall. The wall is "passive", not contributing to the process itself but it will have some consequences out of the process..
No, Process is an active entity. Program, on the other hand, is a passive entity.
This might mean you have gangrene or necrosis. You might also have frostbite.
Diffusion
Cotransport is an active process.
Exocytosis is an active process.
