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