Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Turn things on
Away from the middle
Top of “hump” in energy diagram of reaction
What is IP3?
Speed of movement
Length one step of a motor makes
Type of drugs that treat cancer
Any device that changes some measurable quantity into another measurable quantity
A motor is called this if it can walk continuously along a filament without falling off
Proteins that exchange solutes
Normal though harmful byproduct of oxidative metabolism
The folded bits in the mitochondria
Double membrane around the nucleus
Shut down mitosis
What SOD converts superoxide into
Incorrect tracking of the eye
Monomer buffer
Maximum amount of force a motor can generate
Control where microtubules form and they bypass the time for nucleation.
Stacking by alternating between alpha and beta tubulins
Cause unknown in terms of ALS
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
An assay with kinesin or dynein and microtubules
Load bearing filaments
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Due to multiple copies of a gene the effect of a gene can be enhanced
Protein that forms filaments for muscle contraction
Feeling of motion (spinning)
Energy bearing compound
Elimination of toxins
Protein changes its shape in a way to where it no longer functions
Where a specific kind of RNA (ribosomal) is being made
Allows a reaction to go faster
A substance can be called this if you can put one wavelength in and get a different wavelength out
Question/DefinitionAnswer/Term
What is cAMP?
A temporary protrusion of the surface of an ameboid cell for movement and feeding
What is DAG?
Allow specific solutes to cross membrane
Molecular motor that takes cargo to periphery of cell
Twitching
Stabilizes microtubules, blocking cell division
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Notable example of MTOC
Actin filament stabilizer; leads to liver failure if ingested.
Turn things off
The filling in the mitochondria
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Oxidizes proteins in a more harmful and irreversible way
Inherited
“Hump” to get over on its way to lower energy
Binds the relative cargo
Proteins that transport solutes together
Interacts with hormone; determines ligand specificity
Molecular sized apparatus that converts energy to work
Dynein that is used for cargo transport
A large chunk of the microtubule disassembles rapidly
An assay with actin over myosin
One event makes tons of second messengers
Binds and hydrolyzes GTP
Microtubule based motors that are minus-end directed
Form the tonofilaments of epithelia, found in skin and hair
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
Causes disassembly of microtubules
Handles Oxidative stress in the body.
Too many copies of genes
Makes branch points on actin filaments and nucleates new filament growth.
Using RNA as a template for making protein
Force x distance
What enzymes act upon
Portion that is connected to filament

Altered vision and confusion
Relates time to the mean squared distance traveled
Other proteins or molecules that are necessary to keep the enzyme activated
Rate of using ATP
Molecular motor that takes cargo to center of cell
Same enzyme doing basically the same reaction but in a different way
What is Ca2+?
Acts on ATP to strip off two phosphates turning it into cAMP
What does cAMP activate?
A flattened extension of a cell, by which it moves over or adheres to a surface
Microtubule based motors that are mostly plus-end directed
Small molecules that convey the message from the receptor to the cell interior.
Shuttle that promotes nucleotide exchange
