Question/DefinitionAnswer/Term
Binds the relative cargo
Allow specific solutes to cross membrane
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
A flattened extension of a cell, by which it moves over or adheres to a surface
Accelerates the movement of a solute down it’s electrochemical gradient
Protein that forms filaments for muscle contraction
Growth by the addition of monomers
Twitching
Incorrect tracking of the eye
Turn things off
Shuttle that promotes nucleotide exchange
Copying DNA into RNA
Stacking by alternating between alpha and beta tubulins
Dynein that is used for cilliary and flagellar motion
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Shut down mitosis
Protein changes its shape in a way to where it no longer functions
Interacts with hormone; determines ligand specificity
Feeling of motion (spinning)
Break protein chains through hydrolysis (breaking apart water)
Speed of movement
Proteins that exchange solutes
Amount of time spent generating force
Acts on ATP to strip off two phosphates turning it into cAMP
Small molecules that convey the message from the receptor to the cell interior.
Energy bearing compound
Actin filament stabilizer; leads to liver failure if ingested.
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Makes branch points on actin filaments and nucleates new filament growth.
Faces inside world of body
Cause unknown in terms of ALS
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
Portion that is connected to filament
Causes disassembly of microtubules
Rate of using ATP
Question/DefinitionAnswer/Term
Elimination of toxins
Two different proteins stuck together
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Basic subunit for filaments
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
Other proteins or molecules that are necessary to keep the enzyme activated
Molecular sized apparatus that converts energy to work
One event makes tons of second messengers
Length one step of a motor makes
A large chunk of the microtubule disassembles rapidly
New growth off of the main actin filament
Connecting a hormone to a very specific effector
Binds and hydrolyzes GTP
Microtubule based motors that are minus-end directed
Same enzyme doing basically the same reaction but in a different way
Altered vision and confusion
Molecular motor that takes cargo to center of cell
An assay with actin over myosin
What is IP3?
Double membrane around the nucleus
Microtubule based motors that are mostly plus-end directed
Relates time to the mean squared distance traveled
Due to multiple copies of a gene the effect of a gene can be enhanced
What does cAMP activate?
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Molecular motor that takes cargo to periphery of cell
Using RNA as a template for making protein
What enzymes act upon
What SOD converts superoxide into
Form the tonofilaments of epithelia, found in skin and hair
Faces outside world
Oxidizes proteins in a more harmful and irreversible way
Dynein that is used for cargo transport
Notable example of MTOC
Question/DefinitionAnswer/Term
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Load bearing filaments
Monomer buffer
Something that binds to a receptor
The filling in the mitochondria

What is Ca2+?
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
Allows a reaction to go faster
Normal though harmful byproduct of oxidative metabolism
Type of drugs that treat cancer
An assay with kinesin or dynein and microtubules

Any device that changes some measurable quantity into another measurable quantity
Stabilize nerve axons by maintaining girth
The folded bits in the mitochondria
Plus-end directed, toward the periphery
“Hump” to get over on its way to lower energy
What is cAMP?
