GCU Bio 201 Exam 1 Questions With Correct
Answers
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
