VERSION.
diffusion - CorreCt Answers -Diffusion is when molecules move from an
area of higher concentration to an area of lower concentration to achieve
equilibrium with the two sides of a membrane. (small molecules such as
gases, water, and glycerol as well as lipid-soluble molecules such as
hydrocarbons)
Facilitated diffusion is used for a lipid-insoluble molecule and happens by
carrier proteins binding temporarily to the molecule and releasing it to the
other side. (lipid-insoluble (polar) molecules such as sugars and amino
acids)
active transport - CorreCt Answers -When molecules or ions are pumped
from an area of lower concentration to an area of higher concentration.
This requires extra energy and carrier proteins because the molecules are
going against the concentration gradient.
endocytosis - CorreCt Answers -when a biomacromolecule outside the cell
gets enclosed in the cell membrane and forms a vesicle inside the cell.
phagocytosis - CorreCt Answers -endocytosis of extremely large things like
other cells. Once enclosed, lysosomes fuse with and digest it.
pinocytosis - CorreCt Answers -endocytosis of tiny droplets of fluids. The
cell membrane pinches inward.
, receptor-mediated endocytosis - CorreCt Answers -information transfer
from one cell to another by use of ligands (signaling molecules) that bind to
receptor proteins.
proteins - CorreCt Answers -In facilitated diffusion and active transport,
carrier proteins are used to move lipid-insoluble molecules to the other side
of the membrane.
isotonic - CorreCt Answers -same concentration of solutes inside as outside
the cell
hypertonic - CorreCt Answers -higher concentration of solutes inside the
cell than outside the cell
blood cells will shrivel in the process of equalizing
hypotonic - CorreCt Answers -lower concentration of solutes inside the cell
that outside the cell
blood cells will swell in the process of equalizing
cholesterol - CorreCt Answers -Cholesterol is a lipid that is very
hydrophobic and has one polar hydroxyl group. It joins with phopholipids
and mixes in with the tails to prevent solidification during low
temperatures. It also stabilizes the phospholipd head with the hydroxyl
group by restricting movement in higher temperatures.There are six levels
of organization in the body - what are they? - CorreCt Answers -1) chemical
2) cellular
3) tissue
4) organ structure
