Organelles
This organelle has highly folded membranes.
What are mitochondria?
This molecule is important as it keeps the cell membrane fluid.
What is cholesterol?
This is the movement of water from high to low concentration.
What is osmosis?
These molecules can move directly through the membrane without the help of proteins.
What are small, nonpolar, molecules like oxygen and carbon dioxide?
This size cell is the most efficient at moving substances in and out of the cell.
What are the hydrophilic phosphate heads?
Simple diffusion and facilitated diffusion do not require this.
Minimal amounts of this molecule can move directly through the membrane.
What are water molecules?
This specific protein is used to transport large amounts of water across a membrane.
What are aquaporins?
This part of the ER is responsible for making lipids and detoxifying the cell.
What is the smooth ER?
The part of the membrane that is non-polar.
What are the fatty acid tails?
The movement of molecules from and area of low concentration to high concentration, using energy to move against the gradient.
What is active transport?
Small polar molecules that need transport proteins to move from an area of high concentration to a low concentration.
When the solution outside of the cell has a higher solute concentration than inside the cell, water moves out...
What is a hypertonic situation?
What are mitochondria?
This type of protein in the membrane is responsible for cell-to-cell recognition.
Diffusion that requires a protein to get molecules across a membrane.
What is facilitated diffusion?
When the solute concentration inside the cell is higher than the surrounding environment, water moves into the cell...
What is a hypotonic situation?
This portion of the ER is responsible for creating proteins.
What is the rough ER?
What are integral proteins?
The movement of particles from high to low concentration.
What is diffusion?
When this hormone is activated it there is not enough water in the blood and water needs to be pulled from cells and put back into the bloodstream...
When there is no real net movement of water into and out of the cell...
What is isotonic?
