|
This ratio has to be large in order to be efficient. |
SA:V Ratio |
It's a ratio.

|
What does a Prokaryotic cell not have? |
All the organelles a Eukaryotic cell has. (Cell Wall and Ribosomes are exeptions) |
Where is info packed? **** ton of little things that make protein? It's arms and legs? |
|
|
What do Actin fillaments do? (Microfiliments) |
× Maintain call shape via tension. × Moves cell via muscle contraction or cell "crawling." × Divides animal cells in two. × Moves organelles and cytoplasm in the cell |
|
|
|
Intermediate filaments, what are they? |
× Maintain cell shape via tension × Anchors all organelles |
It's how a cell remains like an oval. |
|
|
Microtubules, what are they? |
× Maintain cell shape via tension × Moves cell via flagella or cilia × Moves chromosomes during cell division × Assists formation of cell plate × Provides tracks for intracellular transport |
Separates gay boys.. They're also roads.. And a plate.. |
|
|
What Does the nucleus do? |
× Stores information (DNA) × Creates ribosomes |
|
|
|
What goes in and out of the nucleus? |
Via Nuclear Pore Complex: × Ribosomal RNA (rRNA) × Messenger RNA (mRNA) × Small molecules |
They both end with -NA |
|
|
What's the difference between unsaturated phospholipids and saturated phospholipids? |
The "Kink!" θ_________ \ \ |
|
|
|
What's the mysterious force that results from fatty acid chain length? |
Vander Vaal Forces |
|
|
|
Is cholesterol just jammed into the plasma membrane? |
Yes. |
|
|
|
What are the 4 things that affect Permeability? |
× Saturation of fatty acids × Fatty acid chain length × Cholesterol concentration × Temperature |
|
|
|
What 3 things affect the fluidity of the lipid bilayer? |
× Phospholipid bilayer × Proteins × Cholesterol |
|
|
|
What are the event phases of Mitosis? |
× Prophase= Chromosomes! × Prometaphase= C-To-Middle! × Metaphase= We are at the middle! × Anaphase= Thy split! × Telephase= NE-Reforms! × Cytokenisis= Division Complete! |
|
|
|
How much DNA do you end up with when you start off with two strands of DNA? #Mitosis |
4 |
|
|
|
Mitosis Promoting Factor, how does it work? |
The amount of Cyclin Dependent Kinase increases up to a certain level it triggers the MPF to start mitosis, once CDK levels off, MPF stops mitosis. |
|
|
|
What's the difference between cell division in animal cells and plant cells? |
Animals - Actin filaments "pinch off" the cell in two, this pinch is known as the cleavage furrow. ( | ) = ( )( ) Plants - Microtubules send vesicles to the center of the dual-cell and create a cell plate. |
|
|
|
What are the primary & secondary structures of DNA? |
Primary - Sequence of nucleotides. Secondary - Double Helix |
|
|
|
What are the Primary, Secondary and Tertiary structures of RNA? |
Primary - Sequence of nucleotides Secondary - Hairpin Tertiary - Complex 3D form |
|
|
|
What's the name of the enzymes involved in DNA synthesis and their functions? |
THE REPLISOME × Helicase= Cuts it in half × SSBP= Prevents reformation × Toipomerase= Allows unwind × Primase= Creates a start for DNA sythesis ( 3' Postion) × DNA Polymerase III= Extend strand × DNA Polymerase I= Removes DNA primer × Ligase= Joins okasaki fragments |
|
|
|
What process is used for Polymerization? |
Condensation/Dehydration - H2O is sqeezed out during the binding process |
|
|
|
What process is used for De-Polymerization |
Hydrolysis - Water is used to break apart monomers |
|
|
|
What is the structure of an amino acid? |
× H- a Hydrogen atom × NH2- an Amino group × COOH- a Carboxyl group × R- a distictive "R-Group" |
|
|
|
What are the 3 types of R-Groups? |
× Polar/Electrically charged- Hydrophilic × Nonpolar- Hydrophobic |
