Movement of molecules from high to low concentration.
Diffusion of water across a selectively permeable membrane.
Facilitated transport requires carrier proteins.
Molecules move against their concentration gradient using energy.
Transport of large particles via vesicle formation.
Equal solute and water concentrations inside and outside the cell.
Cells swell as water enters due to lower solute concentration outside.
Cells shrink as water exits due to higher solute concentration outside.
A pump that moves sodium out and potassium into the cell using ATP.
Process where substances exit the cell via vesicle fusion with the membrane.
Endocytosis of large particles or cells.
Specific molecules bind to receptors, leading to selective uptake.
Movement of molecules from high to low concentration.
Diffusion of water across a selectively permeable membrane.
Requires carrier proteins to assist molecules across the membrane.
Active transport requires energy, while passive transport does not.
Cells swell as water enters due to lower solute concentration outside.
Causes cells to shrink as water exits due to higher solute concentration outside.
No net movement of water; solute concentrations are equal inside and outside.
Movement of large particles via vesicle formation.
Vesicles fuse with the plasma membrane to release substances outside the cell.
Endocytosis of large particles or cells.
Endocytosis of liquids or small particles.
Specific uptake of molecules via receptor proteins.
Facilitate rapid water movement across the plasma membrane.
Transports sodium out and potassium into the cell, creating gradients.
Pressure developed in a system due to osmosis.
Turgor pressure develops, maintaining cell structure.
Disruption of cells due to excessive water intake.
Shrinking of red blood cells in a hypertonic solution.
