Terms in this set (149)
Apoptosis A programmed cell death that is regulated or
programmed. Cellular self-destruction for
elimination or unwanted cell populations
Necrosis Rapid loss of the plasma membrane structure,
organelle swelling, mitochondria dysfunction
What is the #1 cause of cellular hypoxia
injury leading to necrosis
(especially the kidney and heart)
What is the #1 cause of hypoxia? ischemia
Main component of a cell nucleus
, What does the nucleus contain? nucleolus
What is the nucleolus composed RNA, most of cellular DNA, DNA binding
of? proteins, and histones
Why are histone important? histones bind to DNA and fold it into
chromosomes (chromatin) which is essential for
cell division
What are ribosomes? RNA-protein complexes (nucleoproteins) that are
synthesized in the nucleolus and secreted into
the cytoplasm through pores in the nuclear
envelope called nuclear pore complexes (NPCs)
Where can ribosomes be found? cytoplasm and rough ER
what are ribosomes chief function? provides sits for cellular protein synthesis
What is the Golgi apparatus a network of flatten, smooth membranes and
(complex)? vesicles frequently located near the nucleus of
the cell
What does the Golgi apparatus do? takes proteins from the ER and
processes/packages them into small membrane-
bound vesicles called "secretory vesicles, and
refines and directs traffic in the cell
