Question/DefinitionAnswer/Term
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 IP3?
Control where microtubules form and they bypass the time for nucleation.
Energy bearing compound
The folded bits in the mitochondria
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Small molecules that convey the message from the receptor to the cell interior.
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.
What is cAMP?
Allows a reaction to go faster
What is DAG?
Form the tonofilaments of epithelia, found in skin and hair
Binds and hydrolyzes GTP
Turn things off
Binds the relative cargo
Portion that is connected to filament
Incorrect tracking of the eye
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Monomer buffer
Notable example of MTOC
Force x distance
Protein that forms filaments for muscle contraction
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Length one step of a motor makes
What enzymes act upon
Using RNA as a template for making protein
Growth by the addition of monomers
Plus-end directed, toward the periphery
Accelerates the movement of a solute down it’s electrochemical gradient
Turn things on
Stabilize nerve axons by maintaining girth
Altered vision and confusion
A motor is called this if it can walk continuously along a filament without falling off
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Proteins that exchange solutes
Lend lateral strength to tissues, stable, they are not polar
Question/DefinitionAnswer/Term
Cause unknown in terms of ALS
Basic subunit for filaments
Other proteins or molecules that are necessary to keep the enzyme activated
An assay with actin over myosin
Molecular motor that takes cargo to periphery of cell
Same enzyme doing basically the same reaction but in a different way
Shut down mitosis
Protein changes its shape in a way to where it no longer functions
Connecting a hormone to a very specific effector
Makes branch points on actin filaments and nucleates new filament growth.
Due to multiple copies of a gene the effect of a gene can be enhanced
Microtubule based motors that are minus-end directed
Type of drugs that treat cancer
Actin filament stabilizer; leads to liver failure if ingested.
What is Ca2+?
Breaking apart water (hydrolysis) in the process of breaking protein chains
Rate of using ATP
Proteins that transport solutes together
Faces inside world of body
Microtubule based motors that are mostly plus-end directed
Relates time to the mean squared distance traveled
Speed of movement
Dynein that is used for cargo transport
Allow specific solutes to cross membrane
Two different proteins stuck together
Shuttle that promotes nucleotide exchange
Too many copies of genes
A temporary protrusion of the surface of an ameboid cell for movement and feeding
A substance can be called this if you can put one wavelength in and get a different wavelength out
Causes disassembly of microtubules
Stabilizes microtubules, blocking cell division
Where a specific kind of RNA (ribosomal) is being made
Something that binds to a receptor
One event makes tons of second messengers
A flattened extension of a cell, by which it moves over or adheres to a surface
Any device that changes some measurable quantity into another measurable quantity
Question/DefinitionAnswer/Term
Copying DNA into RNA
Top of “hump” in energy diagram of reaction
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
