PAPER COMPLETE SOLUTIONS VERIFIED
◉ 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
◉ endocytosis.
Answer: import of animal cell molecules into vesicles
◉ phagocytosis.
Answer: uptake of very large particles (vacuoles and lysosomes)
(type of endo)
◉ pinocytosis.
Answer: ingestion of extracellular fluid (type of endo)
