Cell Transport Flashcards
1
Q
Hypertonic Solution
A
More solute and less solvent
2
Q
Hypotonic
A
More solvent and less solute
3
Q
Isotonic
A
Equal solute and solvent
4
Q
How will hypertonic and hypotonic things move?
A
hypo to hyper
5
Q
Diffusion
A
Movement from high to low
Small, nonpolar molecules move through the phosphlipids
Ex: Oxygen
6
Q
Facilitated Diffusion
A
Move from high to low
Small, polar molecules move through the protein channel
Ex: Glucose
7
Q
Osmosis
A
Water moves to dilute until equal
8
Q
Protein Pump
A
Forces molecules through against the concentration gradient (low to high)
Requires ATP
Ex: Ions
9
Q
Phagocytosis
A
Engulfing a large solid particle
Requires ATP
Ex: Bacteria
10
Q
Pinocytosis
A
Ingesting liquid into a cell
Requires ATP
Ex: Proteins found in liquid
11
Q
Exocytosis
A
Cell vomit
Release of a large molecule from the cell
Ex: Cell waste
