Connecting a hormone to a very specific effector
A system that’s based in cytoskeleton of neurons that is responsible for transporting materials such as organelles, vesicles… etc.

Any device that changes some measurable quantity into another measurable quantity
The beginning of chemical or physical changes at discrete points in a system. Helps the actin filaments start growing.

Growth by the addition of monomers
Dynein that is used for cilliary and flagellar motion
Molecular motor that takes cargo to periphery of cell
Lend lateral strength to tissues, stable, they are not polar
Rate of using ATP
Faces inside world of body
Makes branch points on actin filaments and nucleates new filament growth.
What SOD converts superoxide into
Molecular sized apparatus that converts energy to work
Oxidizes proteins in a more harmful and irreversible way
Proteins that transport solutes together
Other proteins or molecules that are necessary to keep the enzyme activated
Breaking apart water (hydrolysis) in the process of breaking protein chains

Shuttle that promotes nucleotide exchange
What is Ca2+?
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments

Load bearing filaments
Question/DefinitionAnswer/Term
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Portion that is connected to filament
New growth off of the main actin filament
Allow very specific ions to cross membranes by creating a channel/tunnel through the cell membrane
Small molecules that convey the message from the receptor to the cell interior.
Handles Oxidative stress in the body.
