The folded bits in the mitochondria
Shuttle that promotes nucleotide exchange
Notable example of MTOC
Length one step of a motor makes
Where a specific kind of RNA (ribosomal) is being made
Acts on ATP to strip off two phosphates turning it into cAMP
Actin filament stabilizer; leads to liver failure if ingested.
A flattened extension of a cell, by which it moves over or adheres to a surface
A substance can be called this if you can put one wavelength in and get a different wavelength out
Two different proteins stuck together
What is cAMP?
Binds and hydrolyzes GTP
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Turn things off
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
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
What SOD converts superoxide into
Copying DNA into RNA
Cause unknown in terms of ALS
Microtubule based motors that are minus-end directed
Top of “hump” in energy diagram of reaction
Small molecules that convey the message from the receptor to the cell interior.
Question/DefinitionAnswer/Term
Twitching
Stacking by alternating between alpha and beta tubulins
Breaking apart water (hydrolysis) in the process of breaking protein chains
Using RNA as a template for making protein
“Hump” to get over on its way to lower energy
Force x distance
New growth off of the main actin filament
Basic subunit for filaments
Plus-end directed, toward the periphery
Double membrane around the nucleus
A motor is called this if it can walk continuously along a filament without falling off
Form the tonofilaments of epithelia, found in skin and hair
A large chunk of the microtubule disassembles rapidly
Rate of using ATP
Lend lateral strength to tissues, stable, they are not polar
Interacts with hormone; determines ligand specificity
The filling in the mitochondria
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
Any device that changes some measurable quantity into another measurable quantity
One event makes tons of second messengers
Control where microtubules form and they bypass the time for nucleation.
Binds the relative cargo
Turn things on
Dynein that is used for cilliary and flagellar motion
Away from the middle
What is DAG?
Due to multiple copies of a gene the effect of a gene can be enhanced
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
Molecular sized apparatus that converts energy to work
Amount of time spent generating force
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Altered vision and confusion
What does cAMP activate?
Shut down mitosis
Causes disassembly of microtubules
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
