A flattened extension of a cell, by which it moves over or adheres to a surface
Molecular sized apparatus that converts energy to work
Cause unknown in terms of ALS
Double membrane around the nucleus
The filling in the mitochondria
Due to multiple copies of a gene the effect of a gene can be enhanced
Type of drugs that treat cancer
What is IP3?
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Shut down mitosis

Elimination of toxins
Normal though harmful byproduct of oxidative metabolism
A temporary protrusion of the surface of an ameboid cell for movement and feeding
Faces inside world of body

Acts on ATP to strip off two phosphates turning it into cAMP
A large chunk of the microtubule disassembles rapidly
Dynein that is used for cilliary and flagellar motion
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Growth by the addition of monomers
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.

Actin filament stabilizer; leads to liver failure if ingested.
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Lend lateral strength to tissues, stable, they are not polar
Relates time to the mean squared distance traveled
Monomer concentration [m] at which the rate of monomer addition equals the rate of monomer loss.

“Hump” to get over on its way to lower energy
Control where microtubules form and they bypass the time for nucleation.
Rate of using ATP
Causes disassembly of microtubules
Inherited
Molecular motor that takes cargo to center of cell
What enzymes act upon
Where a specific kind of RNA (ribosomal) is being made
Handles Oxidative stress in the body.
Makes branch points on actin filaments and nucleates new filament growth.
An assay with actin over myosin
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.
Question/DefinitionAnswer/Term
