Bio 3-2
(blank) is the molecule that provides energy for active transport
ATP
(blank) moves oxygen and carbon dioxide from a low concentration to a high concentration
Active Transport
Active transport requires (blank) to move molecules across membranes
Atp (energy)
when molecules move down the concentration gradient it means they are moving from
an area of high concentration to an area of lower concentration
The swelling and bursting of animal cells
cytolysis
gases like oxygen and carbon dioxide move across the cell membrane
diffusion
during diffusion molecules tend to move
down the concentration gradient
when molecules move from high to low along a concentration gradient they are moving
down/with the concentration gradient
when the concentration gradient of a solute inside and outside of a cell is the same, the cell has reached
equilibrium
A concentration (gradient) forms whenever there is a difference in concentration between one place and another
gradient
the shrinking of plant cells happens when a plant cell is placed in this solution
hypertonic
the swelling and bursting of animal cells happens when an animal cell is placed in this solution
hypotonic
energy for active transport comes from a cell's (blank)
mitochondria
the process where amoebas "eat" paramecia
phagocytosis
the shrinking of plant cells when water leaves so the cell membrane pulls away from the cell wall
plasmolysis
The substance that dissolves to make a solution
solute
A small membrane sac used to transport substances through exocytosis and endocytosis
vesicle
substance(s) that are able to pass through an egg cell membrane
water (h2o)
