TRANSPORT OF SUBSTANCES Flashcards
transport of substance that doesn’t need energy.
Passive Transport
Movement of molecules from an area of high concentration to the area of low concentration
Diffusion
movement of water molecules in a semipermeable membrane
Osmosis
Two Types of Passive Transport
Diffusion & Osmosis
Three Types of Tonicity
Hypertonic, Hypotonic, Isotonic
solute concentration is higher outside the cell than that of inside
Hypertonic
solute concentration is lower outside the cell than that of inside
Hypotonic
equal amount of solute inside and outside of the cell
Isotonic
transport of substance that needs energy
Active Transport
Two Types of Active Transport
Membrane pump & Bulk Transport
one of the most important pump in the animal cells is the sodium-potassium pump which moves ions out of the cell and potassium ions into the cell.
Membrane pump
type of active transport that uses vacuoles in transporting materials in and out of cell
Bulk Transport
Two Types of Bulk Transport
Endocytosis & Exocytosis
type of bulk transport that moves particles into the cell
Endocytosis
Endocytosis has two types which is:
Phagocytosis & Pinocytosis
