Does Passive Transport take energy?
Describe the process of Cytolysis
When the cell bursts due to water emerging the cell.
How can sodium diffuse across the membrane?
Does osmosis require energy?
Describe facilitated diffusion
When substances move across the membrane with the help of carrier proteins
What happens to a cells size during exocytosis?
it gets bigger
what is selectively permeable?
when a membrane only lets certain things through it by active or passive transport
What is it called when you put salt water on an onion cell?
a hypertonic reaction
When the molecules of two substances are evenly spread out in a solution
a vacuole that expels excess liquid
movement of large particles
when water leaves the cell and turgor pressure is lost
movement or solutes or liquids
when the cell bursts due to water emerging the cell.
what are the different types of passive transport
Diffusion, osmosis, facilitated diffusion,
when solute concentration is equal
Sprayed perfume spreading in a room
How does sodium-potassium pump work
moving sodium and potassium across the membrane using atp
all types of active transport
sodium potassium pump, endocytosis, exocytosis
what allows ions to cross a cell membrane
through ion channels with the concentration gradient
what does the cell membrane use to transport large molecules across it?
how does the cell remove waste out of the cell
what makes up the cell membrane
phospholipids, carrier proteins, and vesicles
during exocytosis what happens to the cell membrane
it gets bigger
what is hypertonic
what water rushes OUT of the cell
what is hypotonic
when water rushes INTO the cell
what is isotonic
When everything is equal
how does phagocytosis work?
the movement of large particles and lysosomes fuse with vesicles and destroy bacteria or viruses
