(maturation) process in which cells become specialized in structure and function - answer ✔✔-
Differentiation
movement, conductivity, metabolic absorption, secretion, excretion, respiration, reproduction,
communication - answer ✔✔-The eight specialized cellular functions are
Contain a nucleus and other organelles that are bound by membranes. - answer ✔✔-Eukaryotic
cells
plasma membrane, cytoplasm, and intracellular organelles - answer ✔✔-The eukaryotic cell
consists of three general components
A part of the cell containing DNA and RNA and responsible for growth and reproduction -
answer ✔✔-Nucleus
cytoplasmic organelles that are carrying messengers of ribonucleic acid (mRNA) from the
nucleus to the ribosomal sites of protein synthesis - answer ✔✔-Vaults
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). - answer ✔✔-plasma membrane (cell membrane)
, protein molecules on the plasma membrane, in the cytoplasm, or in the nucleus that can
recognize and bind with specific smaller molecules called ligands - answer ✔✔-cellular
receptors
A molecule that binds specifically to a receptor site of another molecule. - answer ✔✔-Ligands
(1) the extracellular membrane, (2) cell adhesion molecules in the cell's plasma membrane, and
(3) specialized cell junctions. - answer ✔✔-Cells are held together by three different means:
(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. - answer ✔✔-Cells
communicate in three main ways
The target cell's detection of a signal molecule coming from outside the cell. - answer ✔✔-
reception
conversion of one form of energy into another - answer ✔✔-Transduction
An action or change in behavior that occurs as a result of a stimulus. - answer ✔✔-response
compound used by cells to store and release energy - answer ✔✔-Adenosine Triphosphate
(ATP)
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. -
answer ✔✔-oxidative phosphorylation
