Unit 3: cells, cell transport, & mitosis Flashcards
Diffusion process:
small particles move from high to low concentration directly through the cell membrane.
Is diffusion passive or active?
Passive
Is protein needed for diffusion to work?
no
The concentration gradient of diffusion is low to high. True or False?
False
Is ATP needed for diffusion?
no
The process of facilitated diffusion is…
large particles moving from high to low concentration through a transport protein
Is facilitated diffusion passive or active?
passive

no
the concentration gradient of facilitated diffusion is….
high to low
The process of Osmosis is….
water moving from high to low concentration through a semi-permeable membrane.
Is Osmosis passive or active?
passive
is a protein needed for Osmosis?
no
Osmosis has a concentration gradient from…
high to low
in the process of Generic Active Transport…..
ATP is used to move particles from low to high concentration through a transport protein.
Generic Active Transport is active. True or false?
false
Is a protein needed for Generic Active Transport?
no
Is energy needed for Generic Active Transport?
yes
the process of Exoctyosis is….
vesicles surround particles and move them out of the cell.
the process of Endocytosis is…..
the membrane pinches inward to bring particles into the cell.

active
Is a protein needed for Endocytosis?
no
