How to Play
Lend lateral strength to tissues, stable, they are not polar
An assay with actin over myosin
Handles Oxidative stress in the body.
Other proteins or molecules that are necessary to keep the enzyme activated
What is DAG?
Breaking apart water (hydrolysis) in the process of breaking protein chains
What is Ca2+?
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
What is cAMP?
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Monomer buffer
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
A flattened extension of a cell, by which it moves over or adheres to a surface
Cause unknown in terms of ALS
Dynein that is used for cargo transport
Feeling of motion (spinning)
Type of drugs that treat cancer
Where a specific kind of RNA (ribosomal) is being made
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Proteins that exchange solutes
Faces outside world
Stacking by alternating between alpha and beta tubulins
Relates time to the mean squared distance traveled

Rate of using ATP
Normal though harmful byproduct of oxidative metabolism
Dynein that is used for cilliary and flagellar motion

Actin filament stabilizer; leads to liver failure if ingested.
“Hump” to get over on its way to lower energy
Molecular sized apparatus that converts energy to work

Any device that changes some measurable quantity into another measurable quantity
Portion that is connected to filament
Elimination of toxins
Allow specific solutes to cross membrane

A temporary protrusion of the surface of an ameboid cell for movement and feeding
Amount of time spent generating force
Notable example of MTOC
Control where microtubules form and they bypass the time for nucleation.
Protein that forms filaments for muscle contraction
Binds the relative cargo
Key activator of Arp2/3 that is itself activated by G protein coupled receptors.
Something that binds to a receptor
