Shut down mitosis
There is a limit as to how fast an enzyme can go; one substrate move in and products move out before the next substrate moves in
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Elimination of toxins
Too many copies of genes
Control where microtubules form and they bypass the time for nucleation.
Amount of time spent generating force

Determines G protein specificity
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
An assay with kinesin or dynein and microtubules
Interacts with hormone; determines ligand specificity
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Feeling of motion (spinning)
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Portion that is connected to filament
Dynein that is used for cilliary and flagellar motion
The filling in the mitochondria
Small molecules that convey the message from the receptor to the cell interior.
What is IP3?
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
The folded bits in the mitochondria
Load bearing filaments
Basic subunit for filaments
Molecular sized apparatus that converts energy to work

Maximum amount of force a motor can generate
Notable example of MTOC
