Passive Transport Flashcards
(9 cards)
Molecules traveling freely across cell membrane such as steroids is a process called _
Simple diffusion
(Also O, CO2)
Another passive transport is done by _
Protein pores
_ is when larger molecules are ferried across membrane
Facilitated transport
Protein channels that ferry different from protein pores because _
Not permanently open
When being ferried, protein channel changes shape slightly after _ allowing chemicals to be released inside the membrane
Chemical has docked with it
Some protein channels only open when _ binds to outer surface of the protein
Messenger molecule
Messenger molecule that binds to surface like a key is often from _
Another cell
Protein pores that open due to messenger molecules binding is a process called _
Receptor-mediated opening of protein pores
Receptor proteins are especially important in _
Neurons
