Unit 5- Cell Transport Vocabulary Quiz

Active Transport

• When there is a difference in solute molecules on either side of the cell membrane

• The movement of materials through a cell membrane using energy

• process by which a cell takes material INTO the cell by infolding of the cell membrane

• Water hating or the inability to dissolve in water

Cholesterol

• The movement of materials through a cell membrane using energy

• the movement of particles from regions of higher concentration to regions of lower concentration

• Helps to restrict the passage of molecules by increasing the packing of phospholipids

• When substances transport across cell membranes using protein carrier or channel molecules

Concentration

• RELEASE of substances out a cell by the fusion of a vesicle with the membrane

• The movement of materials through a cell membrane using energy

• Helps to restrict the passage of molecules by increasing the packing of phospholipids

• A measurement of how much solute exists within a certain volume of solvent

Concentration Gradient

• When there is a difference in solute molecules on either side of the cell membrane

• The movement of particles from regions of higher concentration to regions of lower concentration

• Process by which a cell takes material INTO the cell by infolding of the cell membrane

• RELEASE of substances out a cell by the fusion of a vesicle with the membrane

Diffusion

• Helps to restrict the passage of molecules by increasing the packing of phospholipids

• A measurement of how much solute exists within a certain volume of solvent

• When there is a difference in solute molecules on either side of the cell membrane

Hydrophilic

• When substances transport across cell membranes using protein carrier or channel molecules

• RELEASE of substances out a cell by the fusion of a vesicle with the membrane

• Water loving or having a tendency to mix with, dissolve in, or be wetted by water

• Having a LOWER concentration of solute OUTSIDE than INSIDE the cell

Hydrophobic

• Water loving or having a tendency to mix with, dissolve in, or be wetted by water

• Water hating or the inability to dissolve in water

• Having a HIGHER concentration of solute OUTSIDE than INSIDE the cell

• Having a LOWER concentration of solute OUTSIDE than INSIDE the cell
