Passive Transport

ty this help me in science

so basically passive transport only requires the channel proteins, and the phospholipid bilayer is not used?

not from what ive learned. It's a bit confusing how all youtube videos show passive, active and facilitated as THE THREE WAYS. There are more like 5: 1.)passive diffusion 2.) channels and pores 3.) facilitated diffusion 4.) active primary and 5.)active secondary. Passive diffusion is the only one that does NOT require a protein carrier. only the active transports move UP a gradient, and primary is based on energy used (light, ATP, ect.) and secondary is ion gradient based. hope this helps!!

k thanks :)

Nonono it's still used of course.. But the other passive proteins for channel ones are used mainly for bigger molecules..

Ones that can't really fit through the tiny spaces of the phospholipids bilayer. It's still passive though, just matters on the size.

solute: aufgelöste Stoffe

more concentration moving to less concentration

osmosis.
the best passive transport to me..

solute.. basically its like concentraition. because its passive, eg diffusion, so the solutes diffuse through teh cell membrane from aprts where there is high concentration to parts where it is low. this is a passive process because it is movign down the concentration gradient.Solutes are jus like salt molecules ay i think, hope it helps
