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 injury leading to necrosis (especially the

kidney and heart)


~:- hypoxia




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 of?


~:- RNA, most of cellular DNA, DNA binding 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 (complex)?


~:- a network of flatten, smooth membranes and 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




What are lysosomes and what do they do?


~:- maintain cellular health by removal of toxic cellular components, removal

of useless organelles, termination of signal transduction, and signals cellular

adaption




How does aging affect lysosomes?


~:- leads to progressive loss of lysosomal efficiency which declines the

regenerative capacity of organs and tissue

What functions do lysosomal components integrate?


~:- nutrient abundance, energy levels, and cell stressors and will translate

them into instructions that regulate cellular metabolism toward either

proliferation or inactivity




What is mitochondria responsible for?


~:- cellular respiration, cellular metabolism , and energy production




What does the inner membrane of mitochondria contain?


~:- enzymes of the respiratory chain and are essential to the process of

oxidative phosphorylation that generates most of the cell's ATP




The mitochondrial matrix contains what kind of pathways (1), involve what

two things (2), and metabolizes what three things (3)?


~:- 1- metabolic

2- urea and heme synthesis


3- carbs, proteins, and lipids




What can accumulate intracellularly caused by stresses form metabolic

dearangements?
