How to Play
Rate of using ATP
An assay with kinesin or dynein and microtubules
Type of drugs that treat cancer
Due to multiple copies of a gene the effect of a gene can be enhanced
A flattened extension of a cell, by which it moves over or adheres to a surface
Molecular motor that takes cargo to periphery of cell
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Binds and hydrolyzes GTP
Microtubule based motors that are mostly plus-end directed
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Growth by the addition of monomers
Too many copies of genes
Speed of movement
Portion that is connected to filament
An assay with actin over myosin
Break protein chains through hydrolysis (breaking apart water)
Relates time to the mean squared distance traveled
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
A motor is called this if it can walk continuously along a filament without falling off
What is IP3?
Determines G protein specificity
Acts on ATP to strip off two phosphates turning it into cAMP
Dynein that is used for cilliary and flagellar motion
What does cAMP activate?
Double membrane around the nucleus
Stacking by alternating between alpha and beta tubulins
Copying DNA into RNA
Stabilizes microtubules, blocking cell division
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
The filling in the mitochondria
Actin filament stabilizer; leads to liver failure if ingested.
Breaking apart water (hydrolysis) in the process of breaking protein chains
Accelerates the movement of a solute down it’s electrochemical gradient
Turn things off
Connecting a hormone to a very specific effector
Microtubule based motors that are minus-end directed
“Hump” to get over on its way to lower energy
What enzymes act upon
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
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Allows a reaction to go faster
Faces outside world
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Turn things on
Load bearing filaments
Other proteins or molecules that are necessary to keep the enzyme activated
Using RNA as a template for making protein
Binds the relative cargo
Stabilize nerve axons by maintaining girth
Protein changes its shape in a way to where it no longer functions
Length one step of a motor makes
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Shut down mitosis
Energy bearing compound
Molecular sized apparatus that converts energy to work
Same enzyme doing basically the same reaction but in a different way
Notable example of MTOC
Normal though harmful byproduct of oxidative metabolism
Two different proteins stuck together
Elimination of toxins
Amount of time spent generating force
Maximum amount of force a motor can generate
New growth off of the main actin filament
Molecular motor that takes cargo to center of cell
Handles Oxidative stress in the body.
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Allow specific solutes to cross membrane
Small molecules that convey the message from the receptor to the cell interior.
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Faces inside world of body
Dynein that is used for cargo transport
Lend lateral strength to tissues, stable, they are not polar
Proteins that exchange solutes
Interacts with hormone; determines ligand specificity
Proteins that transport solutes together
Where a specific kind of RNA (ribosomal) is being made
What is cAMP?
What is Ca2+?
Any device that changes some measurable quantity into another measurable quantity
Shuttle that promotes nucleotide exchange

Away from the middle
Something that binds to a receptor
Makes branch points on actin filaments and nucleates new filament growth.
Cause unknown in terms of ALS
Basic subunit for filaments
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
