5 Questions
What is the primary cause of cell death by necrosis in the context of hypoxia and ischemia?
Deficiency of oxygen leading to the failure of energy-dependent metabolic pathways
What is the main source of cellular ATP production during the reduction of oxygen in the mitochondria?
Oxidative phosphorylation
What is the role of the accumulation of p53 protein in response to DNA damage?
Arrests cell cycle for DNA repair; triggers apoptosis if damage is too great
What is the consequence of endoplasmic reticulum stress due to protein misfolding?
Depletes essential proteins leading to cell death
What are the primary causes of inflammation leading to damage of host tissues?
Pathogens, necrotic cells, autoimmune diseases, and allergies
