Question/DefinitionAnswer/Term
Microtubule based motors that are minus-end directed

Basic subunit for filaments
Lend lateral strength to tissues, stable, they are not polar
Oxidizes proteins in a more harmful and irreversible way
Molecular motor that takes cargo to periphery of cell

What is Ca2+?
Breaking apart water (hydrolysis) in the process of breaking protein chains
Portion that is connected to filament

The folded bits in the mitochondria
Stabilizes microtubules, blocking cell division
Shuttle that promotes nucleotide exchange
What is cAMP?
Force x distance
Normal though harmful byproduct of oxidative metabolism
Binds and hydrolyzes GTP
