How to Play
What SOD converts superoxide into
Too many copies of genes
Energy bearing compound
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Relates time to the mean squared distance traveled
Allows a reaction to go faster
Actin filament stabilizer; leads to liver failure if ingested.
What is IP3?
“Hump” to get over on its way to lower energy
What enzymes act upon
New growth off of the main actin filament
Portion that is connected to filament
Faces outside world
Molecular sized apparatus that converts energy to work
Top of “hump” in energy diagram of reaction
A motor is called this if it can walk continuously along a filament without falling off
The filling in the mitochondria
Monomer buffer
Proteins that transport solutes together
Using RNA as a template for making protein
Speed of movement
Lend lateral strength to tissues, stable, they are not polar
Acts on ATP to strip off two phosphates turning it into cAMP
Cause unknown in terms of ALS
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Same enzyme doing basically the same reaction but in a different way
Protein that forms filaments for muscle contraction
Where a specific kind of RNA (ribosomal) is being made
Molecular motor that takes cargo to periphery of cell
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Normal though harmful byproduct of oxidative metabolism
What is Ca2+?
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
Break protein chains through hydrolysis (breaking apart water)
Connecting a hormone to a very specific effector
Turn things off

Microtubule based motors that are mostly plus-end directed
Due to multiple copies of a gene the effect of a gene can be enhanced
Breaking apart water (hydrolysis) in the process of breaking protein chains
Notable example of MTOC
Protein changes its shape in a way to where it no longer functions
Makes branch points on actin filaments and nucleates new filament growth.
Oxidizes proteins in a more harmful and irreversible way
What is cAMP?
What does cAMP activate?
Copying DNA into RNA
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Away from the middle
Maximum amount of force a motor can generate
Type of drugs that treat cancer
Binds and hydrolyzes GTP
An assay with actin over myosin
Handles Oxidative stress in the body.
Dynein that is used for cilliary and flagellar motion
Growth by the addition of monomers
Shuttle that promotes nucleotide exchange
Proteins that exchange solutes
Feeling of motion (spinning)
Elimination of toxins
A large chunk of the microtubule disassembles rapidly
Microtubule based motors that are minus-end directed
Determines G protein specificity
The folded bits in the mitochondria
Plus-end directed, toward the periphery
Interacts with hormone; determines ligand specificity
Rate of using ATP
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Force x distance
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Small molecules that convey the message from the receptor to the cell interior.
Incorrect tracking of the eye
Turn things on
Something that binds to a receptor
Stabilizes microtubules, blocking cell division
Dynein that is used for cargo transport
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Allow specific solutes to cross membrane
A flattened extension of a cell, by which it moves over or adheres to a surface
Molecular motor that takes cargo to center of cell
Amount of time spent generating force
A substance can be called this if you can put one wavelength in and get a different wavelength out
