GCU Bio-201 Exam 1 Questions & Answers Graded
A+ 2024/2025
Pinocytosis - -Cell drinking
Phagocytosis - -Cell eating
Exocytosis - -release of substances outside a cell by the fusion of a vesicle with the membrane.
Endocytosis - -process by which a cell takes material into the cell by infolding of the cell
membrane
osmosis - -Low to High, Diffusion of water through a selectively permeable membrane
Diffusion - -Movement of molecules from an area of higher concentration to an area of lower
concentration.
tonicity - -the ability of a surrounding solution to cause a cell to gain or lose water
isotonic solution - -when the concentration of two solutions is the same (moving in and out
equally)
hypertonic solution - -A solution in which the concentration of solutes is greater outside then
inside the cell that resides in the solution
hypotonic solution - -Solute concentration is less than the inside the cell; cell gains water
oncotic pressure - -pulls fluid into the capillaries and/or prevents fluid from leaving.
hydrostatic pressure - -increases filtration by pushing fluid and solute OUT of the capillaries
, crenation - -This happens when a cell shrinks and shrivels; can result in cell death if severe.
hemolysis - -destruction/split of red blood cells
active transport - -the movement of ions or molecules across a cell membrane into a region of
higher concentration, assisted by enzymes and requiring energy.
passive(facilitated) transport - -the movement of substances across a cell membrane without the
use of energy by the cell
Co-transport - -TWO substances are transported together by one protein no ATPase activity
Countertransport - -One substance is being transported into the cell membrane and the other is
getting transported in the opposite direction.
Simple Diffusion - -transport from high to low concentration, easily flow through cell membrane;
Oxygen is an example
Channel Mediated - -Transport in which only the right shape of molecule gets through, example
little kid shape puzzles.
the structure of the mitochondrion - -This organelle has an outer membrane, intermembrane
space, inner membrane, cristae, & matrix
phosphorylation - -The metabolic process of introducing a phosphate group into an organic
molecule.
Hydrolysis - -how the body breaks the bonds between the last two phosphates in ATP, which is
what gives us energy
ATP synthase - -Makes ATP
