Control where microtubules form and they bypass the time for nucleation.
Shuttle that promotes nucleotide exchange
Turn things on
Microtubule based motors that are mostly plus-end directed
Actin filament stabilizer; leads to liver failure if ingested.
Stabilizes microtubules, blocking cell division
An assay with actin over myosin
Handles Oxidative stress in the body.
Monomer buffer
Altered vision and confusion
Binds and hydrolyzes GTP
Protein that forms filaments for muscle contraction
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Double membrane around the nucleus
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
What is cAMP?
Any device that changes some measurable quantity into another measurable quantity
What is Ca2+?
Allow specific solutes to cross membrane
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Question/DefinitionAnswer/Term
A motor is called this if it can walk continuously along a filament without falling off
A substance can be called this if you can put one wavelength in and get a different wavelength out
Faces outside world
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Proteins that exchange solutes
Twitching
Acts on ATP to strip off two phosphates turning it into cAMP
Protein changes its shape in a way to where it no longer functions
Normal though harmful byproduct of oxidative metabolism
Binds the relative cargo
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Same enzyme doing basically the same reaction but in a different way
Faces inside world of body
Molecular sized apparatus that converts energy to work
New growth off of the main actin filament
An assay with kinesin or dynein and microtubules
Top of “hump” in energy diagram of reaction
Rate of using ATP
What enzymes act upon
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
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
Breaking apart water (hydrolysis) in the process of breaking protein chains
One event makes tons of second messengers
Speed of movement
Something that binds to a receptor
Molecular motor that takes cargo to center of cell
Other proteins or molecules that are necessary to keep the enzyme activated
Stabilize nerve axons by maintaining girth
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Allows a reaction to go faster
Connecting a hormone to a very specific effector
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Energy bearing compound
A flattened extension of a cell, by which it moves over or adheres to a surface
A temporary protrusion of the surface of an ameboid cell for movement and feeding
What is IP3?
Question/DefinitionAnswer/Term
The filling in the mitochondria

Incorrect tracking of the eye
What SOD converts superoxide into
Force x distance
Shut down mitosis
