What does cAMP activate?
Breaking apart water (hydrolysis) in the process of breaking protein chains
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.
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
What is Ca2+?
Two different proteins stuck together
Portion that is connected to filament
Elimination of toxins

Break protein chains through hydrolysis (breaking apart water)
Microtubule based motors that are minus-end directed
Dynein that is used for cilliary and flagellar motion
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
What is DAG?
Causes disassembly of microtubules
Allow specific solutes to cross membrane
Small molecules that convey the message from the receptor to the cell interior.
Connecting a hormone to a very specific effector
Force x distance
What is cAMP?
Control where microtubules form and they bypass the time for nucleation.
Speed of movement
Basic subunit for filaments
Binds and hydrolyzes GTP
Monomer buffer
The filling in the mitochondria
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Feeling of motion (spinning)
Form the tonofilaments of epithelia, found in skin and hair
Relates time to the mean squared distance traveled
Stabilize nerve axons by maintaining girth
Actin filament stabilizer; leads to liver failure if ingested.
Protein changes its shape in a way to where it no longer functions
An assay with actin over myosin
Proteins that exchange solutes
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Allows a reaction to go faster
Energy bearing compound
Copying DNA into RNA
A substance can be called this if you can put one wavelength in and get a different wavelength out
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
Incorrect tracking of the eye
Molecular motor that takes cargo to periphery of cell
“Hump” to get over on its way to lower energy
Altered vision and confusion
Interacts with hormone; determines ligand specificity
Growth by the addition of monomers
Oxidizes proteins in a more harmful and irreversible way
Protein that forms filaments for muscle contraction
Something that binds to a receptor
What enzymes act upon
Faces outside world
Makes branch points on actin filaments and nucleates new filament growth.
Accelerates the movement of a solute down it’s electrochemical gradient
Plus-end directed, toward the periphery
Other proteins or molecules that are necessary to keep the enzyme activated
The folded bits in the mitochondria
Molecular motor that takes cargo to center of cell
Shut down mitosis
A large chunk of the microtubule disassembles rapidly
Where a specific kind of RNA (ribosomal) is being made
Handles Oxidative stress in the body.
Stabilizes microtubules, blocking cell division
Cause unknown in terms of ALS
Away from the middle
Using RNA as a template for making protein
