Solute concentration inside the cell is higher than inside the cell
Water flows into the cell
Hypotonic
Transport proteins will carry the molecules across membrane
Facilitated Diffusion
How will a high temperature affect rate of diffusion?
As temperature increases, the rate of diffusion will also increase
Primary active transport uses what type of energy?
Energy from ATP
Takes in molecules and water
Cell drinking
Pinocytosis
Solute concentration outside the cell is the same as inside the cell
Isotonic
This is the goal of diffusion
Reach equilibrium of molecules on either side of the membrane
How will the concentration gradient affect the rate of diffusion?
As materials reach equilibrium, the rate of diffusion decreases
Secondary active transport uses what type of energy?
Electrochemical energy
Uses receptor proteins with specific binding affinity for certain substances
Receptor-Mediated Endocytosis
Solute concentration outside the cell is higher than inside the cell
Water flows out of the cell
Hypertonic
Substance moves through a semipermeable membrane or a solution without help from transport proteins
Simple Diffusion
How does distance affect the rate of diffusion?
The greater the distance that a substance must travel, the slower the rate of diffusion
In what direction do substances move across the concentration gradient in active transport?
Up/Against
Low concentration to high soncentration
Expels waste from cells
Exocytosis
This type of cell becomes turgid when it is in a hypotonic solution
Plant cell
In what direction will substances move across the plasma membrane?
Down concentration membrane
High concentration to low concentration
How does surface area affect the rate of diffusion?
As surface area increases, the rate of diffusion also increases
This transports sodium out of the cell and potassium into the cell
Sodium Potassium Pump
Large particles are taken in by the cell
Cell eating
Phagocytosis
This is when the cell membrane pulls away from cell wall
Plasmolysis/Plasmolyzed
Your lungs will diffuse what substance into your red blood cells?
Oxygen
Which factor plays a role in why cells are so small?
Distance
What tissues transport water and nutrients in plants?
Type of active transport
Moves particles, large molecules, parts of cells, and whole cells, into a cell
Endocytosis
