A motor is called this if it can walk continuously along a filament without falling off
Where a specific kind of RNA (ribosomal) is being made
An assay with actin over myosin
What is Ca2+?
Speed of movement
Due to multiple copies of a gene the effect of a gene can be enhanced
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

Protein changes its shape in a way to where it no longer functions
Inherited
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Faces outside world
Plus-end directed, toward the periphery

Feeling of motion (spinning)
What does cAMP activate?
Protein that forms filaments for muscle contraction
What enzymes act upon
Shuttle that promotes nucleotide exchange
Shut down mitosis
Portion that is connected to filament
What is cAMP?
Handles Oxidative stress in the body.
Type of drugs that treat cancer
Two different proteins stuck together
Acts on ATP to strip off two phosphates turning it into cAMP

Stacking by alternating between alpha and beta tubulins
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.

Oxidizes proteins in a more harmful and irreversible way
The filling in the mitochondria
Question/DefinitionAnswer/Term
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Molecular motor that takes cargo to periphery of cell
Accelerates the movement of a solute down it’s electrochemical gradient
A large chunk of the microtubule disassembles rapidly
New growth off of the main actin filament
Rate of using ATP

“Hump” to get over on its way to lower energy
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Dynein that is used for cargo transport
An assay with kinesin or dynein and microtubules
Allows a reaction to go faster
Makes branch points on actin filaments and nucleates new filament growth.
Actin filament stabilizer; leads to liver failure if ingested.
Relates time to the mean squared distance traveled
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Microtubule based motors that are mostly plus-end directed
Other proteins or molecules that are necessary to keep the enzyme activated
Force x distance
Turn things off
Notable example of MTOC
What is IP3?

Same enzyme doing basically the same reaction but in a different way
What SOD converts superoxide into
Break protein chains through hydrolysis (breaking apart water)
One event makes tons of second messengers
Binds and hydrolyzes GTP
Using RNA as a template for making protein
Control where microtubules form and they bypass the time for nucleation.
Growth by the addition of monomers
Microtubule based motors that are minus-end directed
Basic subunit for filaments
Turn things on
Double membrane around the nucleus
Molecular motor that takes cargo to center of cell
Question/DefinitionAnswer/Term
Allow specific solutes to cross membrane
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane

Dynein that is used for cilliary and flagellar motion
Elimination of toxins
Interacts with hormone; determines ligand specificity
