Structure 101
Both the cytosol and the cytoskeleton reside here.
What is cytoplasm?
The primary function(s) of the cytoskeleton. (State two of the three)
What is holding the cell's shape; securing organelles to specific regions; allowing movement of cytoplasm, vesicles, and multicellular organisms?
Characterized as the more primitive of the euk vs. prok descriptions.
What is prokaryotic?
What is microfilament?
Only 25nm in diameter
What is a microtubule?
Basic: Sitting at 7 to 7.4.
What is the acidity or basicity of cytosol?
When actin and myosin filaments slide past each other, they trigger such a reaction.
What is contraction?
Prokaryotic cells utilize treadmilling / dynamic instability for:
What are positioning and division?
In microtubules, alpha-tubulin and beta-tubulin build:
What are the 13 polymerized dimers?
Found in both prokaryotic and eukaryotic cells.
What are the cytosol and cytoskeleton?
The cytoskeleton's composition.
What are protein filaments?
Often labeled as an anchor for the nucleus and other organelles.
Involves FtsZ, MreB, and ParM.
What is Prokaryotic?
Average 8nm - 10nm in diameter
What are intermediate filaments?
Found and active during mitosis or meiosis.
What are microtubules?
Found in centrioles and basal bodies; responsible for structural organization.
What are triplet microtubules?
Glucose, heme, urea, and pyrimidines.
What are the products of the reactions that the cytosol assists with?
Eukaryotic cells transport:
What are organelles, vesicles, and chromosomes?
70% water; comprises 50% of cell volume.
The cytoskeleton is similar in function to this cell component.
What is the lipid bilayer?
Found in cilia and flagella; responsible for assisting in cell movement.
What are doublet microtubules?
This allows metabolic pathways for glycolysis and HMP/PPP.
What is cytosol?
Active motor proteins in eukaryotic cells. (There are three)
What are kinesin, dynein, and myosin?
The white blood cell's favorite mode of transport.
What are microfilaments?
Cytosol is heavily compartmentalized by membrane-bound organelles like: (name 3)
What are the endoplasmic reticulum, mitochondria, and Golgi apparatus?
