PASSED
◉ out of
Answer: to move from hypo to iso, water moves ____ cell
◉ into
Answer: to move from hyper to iso, water moves ____ cell
◉ catalyze
Answer: membrane proteins ____ transport
◉ carrier proteins
Answer: integral proteins that move solutes by changing protein
conformation, relatively slow rate of transport, "rocking bananas"
◉ channel proteins
Answer: integral proteins that move specific solutes through pores
passively, gated (exist in open or closed positions)
,◉ red blood cells
Answer: ____ cells have no nucleus, last a couple months, made of
hemoglobin
◉ voltage, ligand (neurotransmitters), mechanical
Answer: types of gated channels
◉ pumps (ATPases)
Answer: integral proteins that move solutes against concentration
gradient with ATP energy
◉ protons (H+)
Answer: most common ions transported by ATPases
◉ charge imbalance
Answer: movement of ions may cause ____ which can cause the
transport of other molecules
◉ electrogenic pump
Answer: transport protein that changes electric charge across a
membrane
◉ NaK pump
, Answer: pumps three Na+ out of the cell for every two K+ pumped
into the cell
◉ coupled transport
Answer: Uses the energy released when a molecule moves by
facilitated diffusion to supply energy to active transport of a
different molecule, ATPase (electrogenic) causes charge imbalance
across membrane, electrochemical gradient provides force for
facilitated diffusion
◉ electrochemical potential gradient
Answer: charge imbalance across membrane caused by ATPase
concentration and electrical component, provides force for
facilitated diffusion in coupled transport
◉ coupled transport of K+ ions
Answer:
◉ co-transport of sucrose
Answer:
◉ exocytosis
Answer: export of animal and plant cell macromolecules by
secretion
