Passive
The movement of solute from high to low concentration
What is Diffusion
This requires a protein pump and cellular energy
What is active transport?
Solute or water will diffuse or undergo osmosis until this happens
What is equilibrium?
The cell membrane is mostly made of these
What are phospholipids?
The space across which molecules travel until equilibrium is established
What is concentration gradient?
The movement of water from high to low concentration
What is osmosis?
The cells money. Needed for active transport
What is ATP?
A cell is at equilibrium with its environment. The solution the cell is in must be this
What is isotonic?
The hydrophobic part of the cell membrane are these
What are lipids?
Lipids hate water, so they are said to be _________. Where as ions and polar things love water so they are said to be ___________.
What is hydrophobic and hydrophilic?
Transport that can go right through the cellular membrane
What is diffusion?
The macromolecule responsible for active transport in the cell membrane
What is a protein?
A cell grows in this solution
What is hypotonic?
Another name for the cell membrane
What is the plasma membrane? Also acceptable is fluid mosaic model or phospholipid bilayer.
What are eukaryotes?
The cell membrane only lets small, nonpolar things through
What is selectively permeable?
Bulk transport inside of the cell
What is endocytosis?
A cell appears shriveled and shrunk in this solution
What is hypertonic?
Allows for transport of large or polar things through the cell membrane
What are membrane proteins?
This type of transport brings liquids into the cell
What is pinocytosis?
Movement of something from high to low concentration through a cell membrane protein
What is facilitated diffusion?
Which organelles are responsible for exocytosis?
What is RER, Golgi, and vesicles?
The channels that water travels through in osmosis
