Question/DefinitionAnswer/Term
Plus-end directed, toward the periphery
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 Ca2+?
Molecular motor that takes cargo to periphery of cell
Amount of time spent generating force
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
What is cAMP?
Stabilize nerve axons by maintaining girth
Proteins that transport solutes together
Shuttle that promotes nucleotide exchange

Allows a reaction to go faster
What is IP3?
Binds the relative cargo
Copying DNA into RNA
Load bearing filaments
Twitching
Away from the middle
Notable example of MTOC
“Hump” to get over on its way to lower energy
Faces inside world of body
Breaking apart water (hydrolysis) in the process of breaking protein chains
Length one step of a motor makes
Molecular motor that takes cargo to center of cell
An assay with actin over myosin
Lend lateral strength to tissues, stable, they are not polar
Oxidizes proteins in a more harmful and irreversible way
A substance can be called this if you can put one wavelength in and get a different wavelength out
Same enzyme doing basically the same reaction but in a different way
Turn things off
Dynein that is used for cilliary and flagellar motion
Allow specific solutes to cross membrane

Normal though harmful byproduct of oxidative metabolism
Question/DefinitionAnswer/Term

Altered vision and confusion
Using RNA as a template for making protein
Due to multiple copies of a gene the effect of a gene can be enhanced
Basic subunit for filaments
What SOD converts superoxide into
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Two different proteins stuck together
Protein changes its shape in a way to where it no longer functions
New growth off of the main actin filament
Any device that changes some measurable quantity into another measurable quantity
Protein that forms filaments for muscle contraction

Growth by the addition of monomers
Type of drugs that treat cancer
The filling in the mitochondria

Feeling of motion (spinning)
Acts on ATP to strip off two phosphates turning it into cAMP

Relates time to the mean squared distance traveled
Proteins that exchange solutes
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Other proteins or molecules that are necessary to keep the enzyme activated
Inherited
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.

Faces outside world
Stacking by alternating between alpha and beta tubulins
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Portion that is connected to filament
Control where microtubules form and they bypass the time for nucleation.
Question/DefinitionAnswer/Term
Handles Oxidative stress in the body.

Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Small molecules that convey the message from the receptor to the cell interior.
Connecting a hormone to a very specific effector
