GCU BIO-201 (EXAM 1) CORRECT
100%
Question :Pinocytosis
Correct answer:Cell drinking
Question :Phagocytosis
Correct answer:Cell eating
Question :Exocytosis
Correct answer:release of substances outside a cell by the
fusion of a vesicle with the membrane.
Question :Endocytosis
Correct answer:process by which a cell takes material into
the cell by infolding of the cell membrane
Question :osmosis
Correct answer:Low to High, Diffusion of water through
a selectively permeable membrane
- | Page
Question :Diffusion
Correct answer:Movement of molecules from an area of
higher concentration to an area of lower concentration.
Question :tonicity
Correct answer:the ability of a surrounding solution to
cause a cell to gain or lose water
Question :isotonic solution
Correct answer:when the concentration of two solutions is
the same (moving in and out equally)
Question :hypertonic solution
Correct answer:A solution in which the concentration of
solutes is greater outside then inside the cell that resides in the solution
Question :hypotonic solution
- | Page
Correct answer:Solute concentration is less than the inside
the cell; cell gains water
Question :oncotic pressure
Correct answer:pulls fluid into the capillaries and/or
prevents fluid from leaving.
Question :hydrostatic pressure
Correct answer:increases filtration by pushing fluid and
solute OUT of the capillaries
Question :crenation
Correct answer:This happens when a cell shrinks and
shrivels; can result in cell death if severe.
Question :hemolysis
Correct answer:destruction/split of red blood cells
Question :active transport
- | Page
Correct answer:the movement of ions or molecules across
a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy.
Question :passive(facilitated) transport
Correct answer:the movement of substances across a cell
membrane without the use of energy by the cell
Question :Co-transport
Correct answer:TWO substances are transported together
by one protein no ATPase activity
Question :Countertransport
Correct answer:One substance is being transported into
the cell membrane and the other is getting transported in the opposite direction.
Question :What are some factors that affect diffusion?
Correct answer:• Temperature
• Solvent Density
