How to Play
Molecular motor that takes cargo to periphery of cell
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Turn things off
Proteins that exchange solutes
What is DAG?
Altered vision and confusion
One event makes tons of second messengers
Makes branch points on actin filaments and nucleates new filament growth.
“Hump” to get over on its way to lower energy
Portion that is connected to filament
Acts on ATP to strip off two phosphates turning it into cAMP
Top of “hump” in energy diagram of reaction
Something that binds to a receptor
A temporary protrusion of the surface of an ameboid cell for movement and feeding
What is cAMP?
An assay with actin over myosin
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
Small molecules that convey the message from the receptor to the cell interior.
Determines G protein specificity
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
Length one step of a motor makes
Protein changes its shape in a way to where it no longer functions
Stabilizes microtubules, blocking cell division
Allow specific solutes to cross membrane
Breaking apart water (hydrolysis) in the process of breaking protein chains
Due to multiple copies of a gene the effect of a gene can be enhanced
What does cAMP activate?
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Notable example of MTOC
Elimination of toxins
Energy bearing compound
Turn things on
Handles Oxidative stress in the body.
Type of drugs that treat cancer
Any device that changes some measurable quantity into another measurable quantity
Force x distance
Causes disassembly of microtubules
Form the tonofilaments of epithelia, found in skin and hair
Other proteins or molecules that are necessary to keep the enzyme activated
Break protein chains through hydrolysis (breaking apart water)
Load bearing filaments
Microtubule based motors that are mostly plus-end directed
Rate of using ATP
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Normal though harmful byproduct of oxidative metabolism
Incorrect tracking of the eye
Oxidizes proteins in a more harmful and irreversible way
Maximum amount of force a motor can generate
Using RNA as a template for making protein
Amount of time spent generating force
Too many copies of genes
Molecular motor that takes cargo to center of cell
Double membrane around the nucleus
A motor is called this if it can walk continuously along a filament without falling off
Microtubule based motors that are minus-end directed
Shut down mitosis
What enzymes act upon
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
What SOD converts superoxide into
Accelerates the movement of a solute down it’s electrochemical gradient
Connecting a hormone to a very specific effector
Dynein that is used for cilliary and flagellar motion
An assay with kinesin or dynein and microtubules
A substance can be called this if you can put one wavelength in and get a different wavelength out
Faces outside world
The filling in the mitochondria
Away from the middle
Interacts with hormone; determines ligand specificity
Faces inside world of body
Shuttle that promotes nucleotide exchange
Growth by the addition of monomers
What is Ca2+?
Protein that forms filaments for muscle contraction
Binds and hydrolyzes GTP
Allows a reaction to go faster
Lend lateral strength to tissues, stable, they are not polar
Where a specific kind of RNA (ribosomal) is being made
A large chunk of the microtubule disassembles rapidly
Cause unknown in terms of ALS
Plus-end directed, toward the periphery
Actin filament stabilizer; leads to liver failure if ingested.
Feeling of motion (spinning)
A flattened extension of a cell, by which it moves over or adheres to a surface
Monomer buffer
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
What is IP3?
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Two different proteins stuck together
Copying DNA into RNA
The folded bits in the mitochondria
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Proteins that transport solutes together
Same enzyme doing basically the same reaction but in a different way
Speed of movement
Binds the relative cargo
Control where microtubules form and they bypass the time for nucleation.
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
