Cells become specialized through the process of - answer differentiation or
maturation
Eight specialized cellular functions are - answer movement, conductivity,
metabolic absorption, secretion, excretion, respiration, reproduction, and
communication
Eukaryotic cells consist of - answer the plasma membrane, the cytoplasm,
and intracellular organelles
What is the nucleus? - answer the largest membrane-bound organelle and
found in the cell's center
Chief functions of the nucleus are? - answer cell division and control of
genetic information
What is cytoplasm (cytoplasmic matrix)? - answer an aqueous solution
(cytosol) that fills the space between the nucleus and the plasma
membrane
Where are organelles found? - answer suspended in the cytoplasm and
enclosed in biologic membranes
What is the endoplasmic reticulum? - answer a network of tubular
channels (cisternae) that extend throughout the outer nuclear membrane.
It specializes in the synthesis and transport of protein lipid components of
most of the organelles
What is the Golgi complex? - answer a network of smooth membranes and
vesicles located near the nucleus
, What does the Golgi complex do? - answer process and package proteins
into secretory vesicles that break away from the Golgi complex and
migrate to a variety of intracellular and extracellular destinations,
including plasma membranes
What are lysosomes? - answer sac-like structures that originate from the
Golgi complex and contain digestive enzymes.
What do lysosomal enzymes do? - answer responsible for digesting most
cellular substances to their basic form, such as amino acids, fatty acids,
and carbohydrates (sugars)
What does cellular injury lead to? - answer a release of the lysosomal
enzymes, causing cellular self-digestion
Peroxisomes - answer similar to lysosomes but contain several enzymes
that either produce or use hydrogen peroxide
Mitochondria - answer contain the metabolic machinery necessary for
cellular energy metabolism
Enzymes of the respiratory chain (electron-transport chain) - answer found
in the inner membrane of the mitochondria and they generate most of the
cell's ATP
What is the cytoskeleton? - answer the bone and muscle of the cell.
composed of protein filaments, microtubules, and actin filaments
Proteins are - answer the major workhorses of the cell
Membrane proteins - answer are synthesized by the ribosome and then
make their way (trafficking) to different locations in the cell
