Connecting a hormone to a very specific effector
Proteins that transport solutes together
What is DAG?
What is IP3?
Made of actin and actin-binding proteins, responsible for cell shape, contraction, motility, and cellular transport
Molecular sized apparatus that converts energy to work
Basic subunit for filaments
Speed of movement
What SOD converts superoxide into
Stabilizes microtubules, blocking cell division

Monomer buffer
Molecular motor that takes cargo to periphery of cell
Two different proteins stuck together
Break protein chains through hydrolysis (breaking apart water)
Same enzyme doing basically the same reaction but in a different way
Small molecules that convey the message from the receptor to the cell interior.
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
Relates time to the mean squared distance traveled
What does cAMP activate?
Type of drugs that treat cancer

Protein that forms filaments for muscle contraction
Away from the middle
Portion that is connected to filament
The folded bits in the mitochondria
Length one step of a motor makes
Normal though harmful byproduct of oxidative metabolism
Altered vision and confusion
Question/DefinitionAnswer/Term
Exchanges three sodium ions OUT and two potassium ions IN utilizing one ATP (ATP releases a P, becomes ADP, causes pump to open)
Maximum amount of force a motor can generate

Other proteins or molecules that are necessary to keep the enzyme activated
Too many copies of genes
Due to multiple copies of a gene the effect of a gene can be enhanced
Protein changes its shape in a way to where it no longer functions
Stacking by alternating between alpha and beta tubulins
Double membrane around the nucleus
Growth by the addition of monomers
Molecular motor that takes cargo to center of cell
Actin filament stabilizer; leads to liver failure if ingested.
Acts on ATP to strip off two phosphates turning it into cAMP
What enzymes act upon
Microtubule based motors that are mostly plus-end directed
Amount of time spent generating force
Where a specific kind of RNA (ribosomal) is being made

Twitching
Control where microtubules form and they bypass the time for nucleation.
Oxidizes proteins in a more harmful and irreversible way
Soda straw tubes, made out of tubulins, used for intracellular transport. Very stiff, grow from the + end
The filling in the mitochondria
