Stabilize nerve axons by maintaining girth
Cause unknown in terms of ALS
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Accelerates the movement of a solute down it’s electrochemical gradient
Proteins that transport solutes together
Stabilizes microtubules, blocking cell division
Monomer buffer
Molecular motor that takes cargo to periphery of cell
Same enzyme doing basically the same reaction but in a different way
Where a specific kind of RNA (ribosomal) is being made
What is IP3?
Dynein that is used for cargo transport
Maximum amount of force a motor can generate
Something that binds to a receptor
Length one step of a motor makes
New growth off of the main actin filament
What is cAMP?
Incorrect tracking of the eye
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
An assay with actin over myosin
Makes branch points on actin filaments and nucleates new filament growth.
Question/DefinitionAnswer/Term
“Hump” to get over on its way to lower energy
Acts on ATP to strip off two phosphates turning it into cAMP
Inherited
Load bearing filaments
Break protein chains through hydrolysis (breaking apart water)
Two different proteins stuck together
Double membrane around the nucleus
Turn things off
Plus-end directed, toward the periphery
Microtubule based motors that are minus-end directed
A large chunk of the microtubule disassembles rapidly
Handles Oxidative stress in the body.
Feeling of motion (spinning)
What is Ca2+?
Faces inside world of body
Faces outside world
Portion that is connected to filament
Too many copies of genes
The filling in the mitochondria
Molecular sized apparatus that converts energy to work
Shut down mitosis
Turn things on
Small molecules that convey the message from the receptor to the cell interior.
Copying DNA into RNA
Proteins that exchange solutes

Lend lateral strength to tissues, stable, they are not polar
A flattened extension of a cell, by which it moves over or adheres to a surface
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Normal though harmful byproduct of oxidative metabolism
Using RNA as a template for making protein
