Cell Transport Vocab

A solution where the solute concentration is equal on the outside and inside of the cell, no net movement of molecules(cell stays the same=equlibrium)

• Hypotonic solution

• Isotonic solution

• Hypertonic solution

• Protein Pumps

Requires NO energy

Movement of molecules from high to low concentration

"with the concentration gradient"

• Passive Transport

• Facilitated Diffusion

• Active Transport

• Endocytosis

Solute concentration is greater outside the cell than inside the cell; cell loses water(shrinks)

• Phospholipid Bilayer

• Hypotonic solution

• Isotonic solution

• Hypertonic solution

Type of Passive Transport

Movement of molecules from high to low concentration

Usually small molecules like carbon dioxide and oxygen

• Diffusion

• Facilitated diffusion

• Passive Transport

• Active Transport

Cell membrane(plasma membrane), controls what enters and leaves a cell.

Made of 2 layers of phospholipids, flexible

• Protein Pumps

• Phospholipid Bilayer

• Hypotonic solution

• Homeostasis

Type of Active Transport

Process by which materials in the cell are released outside of the cell

uses vacuoles or vesicles

• Exocytosis

• Endocytosis

• Osmosis

• Protein Pumps

Solute concentration is less outside the cell that inside the cell; cell gains water (swells)

• Isotonic solution

• Hypotonic solution

• Hypertonic solution

• Phospholipid Bilayer

Type of Active Transport

Process by which a cell takes in material into the cell by infoldings of the cell membrane

Creates vesicles

• Endocytosis

• Exocytosis

• Osmosis

• Protein Pumps

Allows some materials(not all) to pass through

• Homeostasis

• Hypertonic solution

• Semi-permeable

• Completely permeable

Type of Passive Transport

Diffusion of water across a semi permeable membrane

Movement from high to low concentration

• Osmosis

• Endocytosis

• Protein Pumps

• Exocytosis
