Incorrect tracking of the eye
Amount of time spent generating force
What is Ca2+?
A flattened extension of a cell, by which it moves over or adheres to a surface
Protein that forms filaments for muscle contraction
Binds the relative cargo
Proteins that exchange solutes
“Hump” to get over on its way to lower energy
Growth by the addition of monomers
Altered vision and confusion
Dynein that is used for cargo transport
What SOD converts superoxide into
Binds and hydrolyzes GTP
Type of drugs that treat cancer
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
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Maximum amount of force a motor can generate
Notable example of MTOC
Interacts with hormone; determines ligand specificity
The folded bits in the mitochondria
Stabilizes microtubules, blocking cell division
Allows a reaction to go faster
Handles Oxidative stress in the body.
Dynein that is used for cilliary and flagellar motion
Feeling of motion (spinning)
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
One event makes tons of second messengers
New growth off of the main actin filament
Lend lateral strength to tissues, stable, they are not polar
Determines G protein specificity
Question/DefinitionAnswer/Term
Something that binds to a receptor
Load bearing filaments
Shut down mitosis
Where a specific kind of RNA (ribosomal) is being made
Length one step of a motor makes
Speed of movement
Other proteins or molecules that are necessary to keep the enzyme activated
Inherited
Energy bearing compound
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Force x distance
Shuttle that promotes nucleotide exchange
Elimination of toxins
Acts on ATP to strip off two phosphates turning it into cAMP
Form the tonofilaments of epithelia, found in skin and hair
An assay with kinesin or dynein and microtubules
Proteins that transport solutes together
Microtubule based motors that are minus-end directed
Accelerates the movement of a solute down it’s electrochemical gradient
Turn things off
Molecular motor that takes cargo to center of cell
Cause unknown in terms of ALS
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Plus-end directed, toward the periphery
Copying DNA into RNA
Connecting a hormone to a very specific effector
What enzymes act upon
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
Two different proteins stuck together
Oxidizes proteins in a more harmful and irreversible way
Molecular sized apparatus that converts energy to work
Top of “hump” in energy diagram of reaction
Faces outside world
Double membrane around the nucleus
What is cAMP?
A motor is called this if it can walk continuously along a filament without falling off
Question/DefinitionAnswer/Term
Break protein chains through hydrolysis (breaking apart water)
Away from the middle
Control where microtubules form and they bypass the time for nucleation.
Molecular motor that takes cargo to periphery of cell
Microtubule based motors that are mostly plus-end directed
Stabilize nerve axons by maintaining girth
Actin filament stabilizer; leads to liver failure if ingested.
Basic subunit for filaments
An assay with actin over myosin

Relates time to the mean squared distance traveled
Protein changes its shape in a way to where it no longer functions
Allow specific solutes to cross membrane
The filling in the mitochondria
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Small molecules that convey the message from the receptor to the cell interior.

Monomer buffer
Same enzyme doing basically the same reaction but in a different way
Normal though harmful byproduct of oxidative metabolism
Any device that changes some measurable quantity into another measurable quantity
What is IP3?
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
What does cAMP activate?
Due to multiple copies of a gene the effect of a gene can be enhanced
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
