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)
