Control where microtubules form and they bypass the time for nucleation.
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Too many copies of genes
Dynein that is used for cilliary and flagellar motion
Turn things off
Stacking by alternating between alpha and beta tubulins
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

Inherited
Determines G protein specificity
Top of “hump” in energy diagram of reaction
Altered vision and confusion
Break protein chains through hydrolysis (breaking apart water)
Shuttle that promotes nucleotide exchange
Binds and hydrolyzes GTP
Molecular motor that takes cargo to periphery of cell
Other proteins or molecules that are necessary to keep the enzyme activated
An assay with actin over myosin
Something that binds to a receptor
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
New growth off of the main actin filament
Molecular motor that takes cargo to center of cell
Molecular sized apparatus that converts energy to work
Portion that is connected to filament
Protein that forms filaments for muscle contraction
Turn things on
A substance can be called this if you can put one wavelength in and get a different wavelength out
Question/DefinitionAnswer/Term
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Microtubule based motors that are mostly plus-end directed
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Connecting a hormone to a very specific effector
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Causes disassembly of microtubules
Where a specific kind of RNA (ribosomal) is being made
A motor is called this if it can walk continuously along a filament without falling off
Cause unknown in terms of ALS
What is cAMP?
Acts on ATP to strip off two phosphates turning it into cAMP
Force x distance
Double membrane around the nucleus
Normal though harmful byproduct of oxidative metabolism
Proteins that transport solutes together
Breaking apart water (hydrolysis) in the process of breaking protein chains
Monomer buffer

Interacts with hormone; determines ligand specificity
Makes branch points on actin filaments and nucleates new filament growth.
What SOD converts superoxide into
Away from the middle
Microtubule based motors that are minus-end directed
Proteins that exchange solutes

What enzymes act upon
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Stabilizes microtubules, blocking cell division
The filling in the mitochondria
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.

Same enzyme doing basically the same reaction but in a different way
Shut down mitosis
Basic subunit for filaments
What is Ca2+?
Energy bearing compound
