Cell Transport
The macromolecule cell membranes are made out of
What is a lipid?
The term used when cells get rid of large molecules
using ENERGY.
What is exocytosis?
The Sodium-Potassium (Na+/K+) pump is an example of this type of cell transport.
What is active transport?
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 channels or "doors"
What is facilitated diffusion?
The term used for when cells take in larger molecules
NOTE:
pinocytosis - cell drinking ; phagocytosis - cell eating
What is endocytosis?
NOTE: 2 types?
Type of endocytosis called "cell drinking"
What is pinocytosis?
The Sodium-Potassium (Na+/K+) pump requires this to properly function?
What is ATP/Energy?
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?
An animal loves this type of tonicity/solution because there is no net gain of water
What is a isotonic solution?
A plant cell loves this type of tonicity
What is hypotonic?
In passive transport, molecules move from a _______ to ______ concentration
What is high to low?
Active transport requires the presence of this:
What is energy?
This type of solution has a greater concentration of solutes than solvent causing a cell to shrink when placed in it.
What is hypertonic solution
Fatty acids have this property
(Think fatty acid tails of the phospholipid bilayer)
What is hydrophobic?
Glycerol has this property on a phospholipid
What is hydrophilic?
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 that is used specifically for osmosis
What is an aquaporin?
phospholipids
protein channels
glycoproteins
can move and allow movement through it
What are the three main parts of the phospholipid bilayer or plasma membrane?
(fluid mosaic model)
The cell membrane is made of lipids which consists of these two components.
What is glycerol and fatty acids?
The three types of passive transport
What are diffusion, facilitated diffusion, and osmosis?
