Cytoskeleton - ANSWER Fibrous network of proteins.
What does a cytoskeleton do? - ANSWER Organizes cellular bodies and
facilitates movement
What are the 3 types of skeletal structures? - ANSWER Microfilaments,
Intermediate filaments, and Microtubules
Microfilaments - ANSWER Polymers of actin: globular protein. 7nm in
diameter
Polymerization - ANSWER Appears like 2 strands twist together. Has a plus
end that grows faster, and a minus end that grows slow.
Depolymerization - ANSWER Disassembly
Treadmilling - ANSWER Where the plus end polymerizes and the minus end
depolymerizes.
Cortex - ANSWER Network of microfilaments beneath the plasma membrane.
Provides structure and shape to cell.
Microvilli- ANSWER projections of intestinal cells.
