Cell Transport
The type of molecule that move diffuse through cell membranes most rapidly
What is small and nonpolar
This is the cell structure responsible for making proteins
What is a ribosome
A cell placed in this type of solution will stay the same size
What is isotonic
This is the ratio that is used to determine how cell size influences a cell.
SA/V Ratio
This general size of cell has a relatively low surface area to volume ratio
What is a large cell
If a substance diffusing across the cell membrane reaches equilibrium, do molecules still cross the cell membrane?
Yes, there is no longer a NET movement
This organelle packages and places a chemical tag on molecules in order to deliver the molecule to the correct location in an organism
Golgi Body (apparatus)
A cell placed in this type of solution will shrink
What is hypertonic
A cell that is smaller will be much better at doing what?
Transporting materials across the membrane
This is the name for a solution with higher solutes than the cell.
Hypertonic
If a cell needs to keep a large concentration of K+ inside of its membrane, this process is used
Active transport
This organelle synthesizes lipids and steroids
Smooth ER
You solve for this variable by using the following equation:
? = -iCRT
Solute Potential
A cell that is larger is much better used for what purpose?
Storage
These organelles have a double membrane (3).
Nucleus, mitochondria, chloroplast
This is the name of the process where a cell takes in a large quantity of molecules rapidly
Endocytosis
During endocytosis, cells can take in nutrients from their surroundings and then store them using these organelles.
Vacuole
If a cell with a 10% solute concentration is placed in a solution with a 15% solute concentration, what direction will water move?
Out of the cell
Which is more efficient - a medium sized cell, or two smaller cells working together?
Two smaller cells working together.
This is the name for the folds of the inner mitochondrial membrane.
Cristae
When a cell is exporting a protein in mass quantities, what 3 organelles are involved?
Rough ER, Golgi Body, Vesicle
This organelle can fuse with a vacuole to destroy unnecessary cellular components.
Lysosome
This is the value for Pressure Potential when the container is exposed to the open air.
O
This is a way of increasing surface area without increasing volume dramatically.
Membrane folding
These are the 4 things all cells have in common.
DNA, Cell Membrane, Cytoplasm, Ribosomes
