transporters
_______ _______ uses the energy of a molecule gradient to transport it in and out of the cell
passive transport
___ ____ uses cellular energy to transport a molecule in and out of the cell
active transport
____ ____ transport use ATP for energy to transport molecules
primary active
___ ___ hydroloyzes ATPase to open the channel
ABC ATPase
____ _____ transport uses charge or gradient of another molecule to transport a molecule
secondary active
___ ___ uses a gradient from one ion to transport another against its gradient
MFS transport
___ is a proten channel that uses charge to pull charged ions across the membrane
uniport
MFS transporter that brings a molecule the same direction as the molecule following its gradient
symport
MFS transporter that brings a molecule opposite direction as the molecule following its gradient
antiport
_____ system uses a complicated pathway to regulate glucose transport
phosphotransferase
Type _ Secretory system passes both membranes in one step
I
Three proteins line up to produce channel to kick antibiotic out of cell
drug efflux pump
_ allows transport across both bacterial membranes and host membrane to secrete toxins; has ball protein that interacts with host cell
needle complex
secretes toxins into host cell through needle complex
syringe secretion
Type _ secretory system transports protein through inner membrane then transports through separate protein on outer membrane
II
_ keeps the protein from folding so it can get through inner membrane protein
chaperone
____ ____is a leader peptide on petide chain that tells the chaperone to transport it out
