, What is the cytoskeleton? - ✔✔the "bone and muscle" of the cell. The internal skeleton is composed of a network of
protein filaments, including microtubules and actin filaments (microfilaments).
What is the plasma membrane? - ✔✔encloses the cell and, by controlling the movement of substances across it, exerts a
powerful influence on metabolic pathways
What is signal transduction? - ✔✔The transfer of molecular signals from the exterior to the interior of a cell. If not done
apoptosis occurs
What is protein regulation and what is it composed of? - ✔✔protein homeostasis and is defined by the proteostasis
network. This network is composed of ribosomes (makers), chaperones (helpers), and protein breakdown or proteolytic
systems. Malfunction of these systems is associated with disease.
What do protein receptors do? - ✔✔on the plasma membrane, enable the cell to interact with other cells and with
extracellular substances
What means accomplish cell-to-cell adhesions? - ✔✔(1) the extracellular membrane, (2) cell adhesion molecules in the
cell's plasma membrane, and (3) specialized cell junctions.
What makes up the extracellular matrix and what does it do? - ✔✔(1) fibrous structural proteins (collagen and elastin),
(2) adhesive glycoproteins, and (3) proteoglycans and hyaluronic acid. The matrix helps regulate cell growth, movement,
and differentiation.
How do cells communicate? - ✔✔(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.
How is intercellular signaling done? - ✔✔contact-dependent, paracrine, hormonal, neurohormonal, and
neurotransmitter.
What is ATP? - ✔✔Adenosine Triphosphate - ENERGY - is required for active transport.
What is anabolism? - ✔✔energy-using process of metabolism
