Cell Transport
The macromolecule cell membranes are made out of
What is a lipid? (or phospholipid)
This is also known as "cell eating"
What is phagocytosis?
The term used to describe the diffusion of water
What is osmosis?
This type of passive transport allows molecules to enter and exit through specific protein channels.
What is facilitated diffusion?
Type of endocytosis called "cell drinking"
What is pinocytosis?
The type of solution where the concentration of solute is equal on both sides
What is an isotonic solution?
In active transport, molecules move from ______ to _______ concentrations.
What is low to high?
This type of solution has a greater concentration of solvent than solute; as a result if a cell is placed in it, the cells will usually swell
What is hypotonic solution?
Red blood cells love this type of tonicity (solution)
What is isotonic?
In passive transport, molecules move from a _______ to ______ concentration
What is high to low?
Active transport requires the presence of this:
What is energy? (ATP also accepted)
This type of solution has a greater concentration of solutes than solvent (higher concentration in solution than the cell)
What is hypertonic solution
Fatty acid tails have this property (water fearing)
What is hydrophobic?
This term means that the cell membrane lets some things in while keeping other things out.
What is selective permeability?
This is the type of protein channel is used specifically for osmosis?
What is an aquaporin?
This term describes the cell membrane layer and what it is made out of, another name for the cell membrane
What is the phospholipid bilayer or plasma membrane?
The three types of passive transport
What are diffusion, facilitated diffusion, and osmosis?
