Question/DefinitionAnswer/Term
Where a specific kind of RNA (ribosomal) is being made
Dynein that is used for cilliary and flagellar motion
What is IP3?
Causes disassembly of microtubules
Protein that forms filaments for muscle contraction
What is DAG?
Top of “hump” in energy diagram of reaction
Stacking by alternating between alpha and beta tubulins
The filling in the mitochondria
Normal though harmful byproduct of oxidative metabolism
Determines G protein specificity

Stabilizes microtubules, blocking cell division
Maximum amount of force a motor can generate
Molecular sized apparatus that converts energy to work
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
Growth by the addition of monomers
A temporary protrusion of the surface of an ameboid cell for movement and feeding
“Hump” to get over on its way to lower energy
Proteins that exchange solutes
New growth off of the main actin filament
Using RNA as a template for making protein
Portion that is connected to filament
Due to multiple copies of a gene the effect of a gene can be enhanced
Form the tonofilaments of epithelia, found in skin and hair
Copying DNA into RNA
Incorrect tracking of the eye
Microtubule based motors that are mostly plus-end directed
A motor is called this if it can walk continuously along a filament without falling off
Length one step of a motor makes
An assay with actin over myosin
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Binds and hydrolyzes GTP
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Question/DefinitionAnswer/Term
Lend lateral strength to tissues, stable, they are not polar
A flattened extension of a cell, by which it moves over or adheres to a surface
Rate of using ATP
Stabilize nerve axons by maintaining girth
Turn things on
Control where microtubules form and they bypass the time for nucleation.
Dynein that is used for cargo transport
Any device that changes some measurable quantity into another measurable quantity
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Plus-end directed, toward the periphery
Small molecules that convey the message from the receptor to the cell interior.
Energy bearing compound
Accelerates the movement of a solute down it’s electrochemical gradient
Other proteins or molecules that are necessary to keep the enzyme activated
Speed of movement
Cause unknown in terms of ALS
What is cAMP?
What SOD converts superoxide into
What enzymes act upon
Something that binds to a receptor
Feeling of motion (spinning)
Proteins that transport solutes together
Notable example of MTOC
Binds the relative cargo
Molecular motor that takes cargo to center of cell
Faces outside world
A large chunk of the microtubule disassembles rapidly
Amount of time spent generating force
Protein changes its shape in a way to where it no longer functions
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
One event makes tons of second messengers
Connecting a hormone to a very specific effector
Faces inside world of body
Two different proteins stuck together
Interacts with hormone; determines ligand specificity
Question/DefinitionAnswer/Term
Basic subunit for filaments
Allows a reaction to go faster
Makes branch points on actin filaments and nucleates new filament growth.
What does cAMP activate?
Force x distance
Acts on ATP to strip off two phosphates turning it into cAMP
Load bearing filaments
Allow specific solutes to cross membrane
Altered vision and confusion
Microtubule based motors that are minus-end directed

Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Handles Oxidative stress in the body.
Relates time to the mean squared distance traveled
Double membrane around the nucleus
Away from the middle
Elimination of toxins
An assay with kinesin or dynein and microtubules
Shuttle that promotes nucleotide exchange
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
The folded bits in the mitochondria

A substance can be called this if you can put one wavelength in and get a different wavelength out
Twitching
Breaking apart water (hydrolysis) in the process of breaking protein chains
Oxidizes proteins in a more harmful and irreversible way
Turn things off
Type of drugs that treat cancer
Monomer buffer
Molecular motor that takes cargo to periphery of cell
