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?
This many potassium is needed for the Na/K pump
What is active transport involving sodium?
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 must allow 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?
This many sodium are needed for the Na/K pump
What is 3?
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
no net gain of water
What is isotonic?
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
Hyper - high solute - like syrup
lose water --- syrup egg shrunk
What is hypertonic solution
NOTE: will the cell gain or lose water?
Fatty acids have this property
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 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, these are the two components
head is water __________
Tail is water __________________
What is glycerol and fatty acids?
Head - water loving
Tail --------- water hating
The three types of passive transport
What are diffusion, facilitated diffusion, and osmosis?
