Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
What is cAMP?
Too many copies of genes
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Dynein that is used for cilliary and flagellar motion
Connecting a hormone to a very specific effector
Makes branch points on actin filaments and nucleates new filament growth.
Inherited
Interacts with hormone; determines ligand specificity
Twitching
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments

What does cAMP activate?
What SOD converts superoxide into
The filling in the mitochondria
Relates time to the mean squared distance traveled
Plus-end directed, toward the periphery
Proteins that transport solutes together
A substance can be called this if you can put one wavelength in and get a different wavelength out
Breaking apart water (hydrolysis) in the process of breaking protein chains
Double membrane around the nucleus
Shut down mitosis
A motor is called this if it can walk continuously along a filament without falling off
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
Type of drugs that treat cancer
Length one step of a motor makes
Basic subunit for filaments

Growth by the addition of monomers
Force x distance
What enzymes act upon
Actin filament stabilizer; leads to liver failure if ingested.
Using RNA as a template for making protein
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Rate of using ATP
Feeling of motion (spinning)
Elimination of toxins
Load bearing filaments
Something that binds to a receptor
Oxidizes proteins in a more harmful and irreversible way
Turn things on
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Other proteins or molecules that are necessary to keep the enzyme activated
Monomer buffer
Energy bearing compound
Binds and hydrolyzes GTP
Two different proteins stuck together
Where a specific kind of RNA (ribosomal) is being made
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Accelerates the movement of a solute down it’s electrochemical gradient
Form the tonofilaments of epithelia, found in skin and hair
Small molecules that convey the message from the receptor to the cell interior.
An assay with kinesin or dynein and microtubules
Control where microtubules form and they bypass the time for nucleation.
Normal though harmful byproduct of oxidative metabolism
Causes disassembly of microtubules
Question/DefinitionAnswer/Term

A flattened extension of a cell, by which it moves over or adheres to a surface
One event makes tons of second messengers
Any device that changes some measurable quantity into another measurable quantity
Altered vision and confusion
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
