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 type 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
Name a membrane bound organelle
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
A cell is placed in a hypertonic solution. After 24 hours, you would expect the cell to now be _____ with the solution
isotonic
What is double membrane, circular DNA, contains ribosomes, or can reproduce on their own.
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
What is nucleus --> ribosome --> rough ER --> transport vesicle --> Golgi body --> secretory vesicle --> cell membrane
True or False: Water can move across the lipid bilayer on its own, but very slowly.
What is true?
This organelle can fuse with a vacuole to destroy unnecessary cellular components.
Lysosome
A cell is placed in an open container. Both the cell and the solution are at 27 C and contain 1.0 M of solute. The cell contains glucose while the solution contains Calcium Chloride. Which way will the water move?
Out of the cell
Calculate the surface area to volume ratio for a cube that has 4mm sides and a cube that has 6mm sides.
What is 1.5 and 1
