Load bearing filaments
What SOD converts superoxide into
Growth by the addition of monomers
Something that binds to a receptor
Top of “hump” in energy diagram of reaction
Allows a reaction to go faster

Binds the relative cargo
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Basic subunit for filaments
Plus-end directed, toward the periphery
Type of drugs that treat cancer
Double membrane around the nucleus
Elimination of toxins
Protein changes its shape in a way to where it no longer functions
Dynein that is used for cilliary and flagellar motion
Allow specific solutes to cross membrane
Accelerates the movement of a solute down it’s electrochemical gradient
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport

Energy bearing compound
Shut down mitosis
New growth off of the main actin filament

Question/DefinitionAnswer/Term

Dynein that is used for cargo transport
Microtubule based motors that are mostly plus-end directed
A large chunk of the microtubule disassembles rapidly
Relates time to the mean squared distance traveled
