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
Condensation of chromatin into chromosomes occur during this stage of the cell cycle.
What is Mitosis (or Prophose)
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
What is the resulting complex when mitotic cyclins bind to Cdks in G2 phase?
MPF (mitosis promoting factor)
A cell spends roughly what percentage of its time in the M-Phase?
10%
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
This molecule involved in regulating cell division stays in a constant concentration throughout the cell cycle
What is cdk (cyclin-dependent kinase)
A Chi-Square value above the critical value on the chi-square chart would lead you to this conclusion.
What is to reject the null hypothesis
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
TRUE or False: Once activated, the MPF signals the cell's exit from G1 and entry into G2 Phase.
False
Daily Double: What book series is Mr. O'Connor currently reading?
The Lord of the Rings
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
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
In order for a cell to develop cancer, a mutation needs to occur in which 2 types of genes
A tumor-suppressor gene and a proto-oncogene
What is the correct order of ALL stages of the M-phase?
Prophase, Metaphase, Anaphase, Telophase, Cytokinesis
