Oxidizes proteins in a more harmful and irreversible way
Allow specific solutes to cross membrane
Any of various pathologic changes seen in living organisms in response to excessive levels of cytotoxic oxidants and free radicals in the environment.
What enzymes act upon
A flattened extension of a cell, by which it moves over or adheres to a surface
Microtubule based motors that are mostly plus-end directed
Protein constituents know how to orient themselves to create the cytoskeleton via long filaments
Acts on ATP to strip off two phosphates turning it into cAMP
Lend lateral strength to tissues, stable, they are not polar
Question/DefinitionAnswer/Term
Portion that is connected to filament
Other proteins or molecules that are necessary to keep the enzyme activated
Turn things off
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport

Protein changes its shape in a way to where it no longer functions
Turn things on
Due to multiple copies of a gene the effect of a gene can be enhanced
Proteins that exchange solutes
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?
Connecting a hormone to a very specific effector
Dynein that is used for cilliary and flagellar motion
What does cAMP activate?
“Hump” to get over on its way to lower energy

An assay with actin over myosin
Twitching
Dynein that is used for cargo transport
