Question/DefinitionAnswer/Term
What is cAMP?
Rate of using ATP
An assay with kinesin or dynein and microtubules
Dynein that is used for cilliary and flagellar motion
Makes branch points on actin filaments and nucleates new filament growth.
Oxidizes proteins in a more harmful and irreversible way
Actin filament stabilizer; leads to liver failure if ingested.
Molecular sized apparatus that converts energy to work
Force x distance
Altered vision and confusion
Plus-end directed, toward the periphery
Portion that is connected to filament
Break protein chains through hydrolysis (breaking apart water)
Allows a reaction to go faster
Breaking apart water (hydrolysis) in the process of breaking protein chains
Faces inside world of body
Microtubule based motors that are mostly plus-end directed
What does cAMP activate?
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
Stabilizes microtubules, blocking cell division
Growth by the addition of monomers
Protein changes its shape in a way to where it no longer functions
Basic subunit for filaments
Any device that changes some measurable quantity into another measurable quantity
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
Small molecules that convey the message from the receptor to the cell interior.
Twitching
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Connecting a hormone to a very specific effector
What is DAG?
Stacking by alternating between alpha and beta tubulins
Microtubule based motors that are minus-end directed
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Normal though harmful byproduct of oxidative metabolism
Binds the relative cargo
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Question/DefinitionAnswer/Term
Too many copies of genes
Two different proteins stuck together
Notable example of MTOC
Causes disassembly of microtubules
Determines G protein specificity
One event makes tons of second messengers
“Hump” to get over on its way to lower energy
Something that binds to a receptor
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Proteins that exchange solutes
Speed of movement
Feeling of motion (spinning)
Faces outside world
Other proteins or molecules that are necessary to keep the enzyme activated
Copying DNA into RNA
What is Ca2+?
The filling in the mitochondria
Same enzyme doing basically the same reaction but in a different way
Where a specific kind of RNA (ribosomal) is being made
Handles Oxidative stress in the body.
Monomer buffer
Dynein that is used for cargo transport
Shut down mitosis
Incorrect tracking of the eye
Type of drugs that treat cancer
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Molecular motor that takes cargo to center of cell
What SOD converts superoxide into
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Lend lateral strength to tissues, stable, they are not polar
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Protein that forms filaments for muscle contraction
What is IP3?
A substance can be called this if you can put one wavelength in and get a different wavelength out
Question/DefinitionAnswer/Term
What enzymes act upon
Amount of time spent generating force
Due to multiple copies of a gene the effect of a gene can be enhanced
Elimination of toxins

Shuttle that promotes nucleotide exchange
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Interacts with hormone; determines ligand specificity

Double membrane around the nucleus
An assay with actin over myosin
Away from the middle
A flattened extension of a cell, by which it moves over or adheres to a surface
Turn things off
Form the tonofilaments of epithelia, found in skin and hair
Relates time to the mean squared distance traveled
Top of “hump” in energy diagram of reaction
A motor is called this if it can walk continuously along a filament without falling off

Inherited
Accelerates the movement of a solute down it’s electrochemical gradient
Control where microtubules form and they bypass the time for nucleation.

Energy bearing compound
Turn things on
Acts on ATP to strip off two phosphates turning it into cAMP
