Osmosis is the tendency of fluid to pass through a semi-permeable membrane until there is an equal concentration of fluid on each side of the membrane. The fluid in not transported, movement is self induced
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion
Active transport
Believe it or not, cyanide kills us by inhibiting active transport, to such an extent that substances can no longer be transferred across cell membranes. This is one example of a substance that stops the process of active transport dead in its tracks.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Coupled transport is an example of active transport.
Endocytosis is an example of active transport.
It is the active transport of liquids in vesicles into and out of a cell so it uses metabolic energy, thus active
When food moves across a cell membrane, it requires Active Transport.
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion
An example of active transport is sugar molecules going into a cell. It cannot pass right through like water and oxygen so it uses active transport.Diffusion
it's an example of secondary active transport.
sodium-potassium pump
Active transport
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
secondary active transport
Hydrogen (H+) pumps.
