Differentiation - ans-(maturation) process in which cells become specialized in
structure and function
The eight specialized cellular functions are - ans-movement, conductivity, metabolic
absorption, secretion, excretion, respiration, reproduction, communication
Eukaryotic cells - ans-Contain a nucleus and other organelles that are bound by
membranes.
The eukaryotic cell consists of three general components - ans-plasma membrane,
cytoplasm, and intracellular organelles
Nucleus - ans-A part of the cell containing DNA and RNA and responsible for growth
and reproduction
Vaults - ans-cytoplasmic organelles that are carrying messengers of ribonucleic acid
(mRNA) from the nucleus to the ribosomal sites of protein synthesis
plasma membrane (cell membrane) - ans-It's function is to protect the cell and control
what goes in and out. It is not a solid structure. It is made of millions of smaller
molecules so it is flexible and porous (allows things to pass through it).
, cellular receptors - ans-protein molecules on the plasma membrane, in the cytoplasm,
or in the nucleus that can recognize and bind with specific smaller molecules called
ligands
Ligands - ans-A molecule that binds specifically to a receptor site of another molecule.
Cells are held together by three different means: - ans-(1) the extracellular
membrane, (2) cell adhesion molecules in the cell's plasma membrane, and (3)
specialized cell junctions.
Cells communicate in three main ways - ans-(1) they form protein channels (gap
junctions); (2)
they display receptors that affect intracellular processes or other cells in direct
physical
contact; and (3) they use receptor proteins inside the target cell.
reception - ans-The target cell's detection of a signal molecule coming from outside
the cell.
Transduction - ans-conversion of one form of energy into another
response - ans-An action or change in behavior that occurs as a result of a stimulus.
Adenosine Triphosphate (ATP) - ans-compound used by cells to store and release
energy
oxidative phosphorylation - ans-Part of the electron transport chain. A process
occurring in the mitochondria that results in the formation of ATP from the flow of
electrons across the inner membrane to bind with oxygen.
Resting Membrane Potential (RMP) - ans-charge difference across the plasma
membrane
