Apoptosis CORRECT ANS-A programmed cell death that is regulated or programmed.

Cellular self-destruction for elimination or unwanted cell populations




Necrosis CORRECT ANS-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)

CORRECT ANS-hypoxia




What is the #1 cause of hypoxia? CORRECT ANS-ischemia




Main component of a cell CORRECT ANS-nucleus

and metabolizes what three things (3)? CORRECT ANS-1- metabolic


2- urea and heme synthesis


3- carbs, proteins, and lipids




What can accumulate intracellularly caused by stresses form metabolic dearangements?

CORRECT ANS-carbs, proteins, and lipids
