GCU Bio-201 Exam 1 Test Questions and Answers Graded A+
Pinocytosis Cell drinking
Phagocytosis Cell eating
release of substances outside a cell by the fusion of a
Exocytosis
vesicle with the membrane.
process by which a cell takes material into the cell by
Endocytosis
infolding of the cell membrane
Low to High, Dittusion of water through a selectively per-
osmosis
meable membrane
Movement of molecules from an area of higher concen-
Dittusion
tration to an area of lower concentration.
the ability of a surrounding solution to cause a cell to gain
tonicity
or lose water
when the concentration of two solutions is the same (mov-
isotonic solution
ing in and out equally)
A solution in which the concentration of solutes is greater
hypertonic solution
outside then inside the cell that resides in the solution
Solute concentration is less than the inside the cell; cell
hypotonic solution
gains water
pulls fluid into the capillaries and/or prevents fluid from
oncotic pressure
leaving.
increases filtration by pushing fluid and solute OUT of the
hydrostatic pressure
capillaries
This happens when a cell shrinks and shrivels; can result
crenation
in cell death if severe.
hemolysis destruction/split of red blood cells
active transport
1/6
, the movement of ions or molecules across a cell mem-
brane into a region of higher concentration, assisted by
enzymes and requiring energy.
the movement of substances across a cell membrane with-
passive(facilitated) transport
out the use of energy by the cell
TWO substances are transported together by one protein
Co-transport
no ATPase activity
One substance is being transported into the cell mem-
Countertransport brane and the other is getting transported in the opposite
direction.
transport from high to low concentration, easily flow
Simple Dittusion
through cell membrane; Oxygen is an example
Transport in which only the right shape of molecule gets
Channel Mediated
through, example little kid shape puzzles.
This organelle has an outer membrane, intermembrane
the structure of the mitochondrion
space, inner membrane, cristae, & matrix
The metabolic process of introducing a phosphate group
phosphorylation
into an organic molecule.
how the body breaks the bonds between the last two
Hydrolysis
phosphates in ATP, which is what gives us energy
ATP synthase Makes ATP
ATP-ase (Enzyme) breaks down ATP
the chemical processes that occur within a living organism
Metabolism
in order to maintain life.
Glucose A simple sugar that is an important source of energy.
(adenosine triphosphate) main energy source that cells
ATP
use for most of their work
ADP
