Patho
True/False
Indicate whether the sentence or statement is true or false.
____ 1. Eukaryotic cells are characterized by a lack of a distinct nucleus, whereas prokaryotic cells have intracellular compartments bordered by membranes and a well-defined nucleus.
____ 2. Lipids and proteins are the major components of the plasma membrane.
____ 3. Lysosomes remain fully active by maintaining an acid pH created by pumping hydrogen ions into their interiors.
____ 4. The chief function of ribosomes is to provide sites for lipid synthesis.
____ 5. If cells are deprived of communication from extracellular chemical messengers, most cells experience apoptosis.
____ 6. Non-dividing cells, such as myocardial fibers, are capable of hypertrophy, but not hyperplasia.
____ 7. Dysplasia is a common type of normal cellular adaptation.
____ 8. Hypertrophy and hyperplasia rarely occur together.
____ 9. Noise, illumination, and prolonged vibrations can cause cellular injury.
____ 10. Irreversible damage to the myocardium can be detected by elevation in the contractile protein called troponin, which is released from the myocardial muscle.
____ 11. Chemical injuries initiate biochemical reactions that damage cell membrane by decreasing the permeability of the plasma membrane.
____ 12. Aging is the result of a genetically controlled development program or built-in self-destructive processes.
____ 13. Chromosome abnormalities are the leading cause of mental retardation and miscarriages.
____ 14. The main function of natural killers cells is recognition and elimination of bacteria.
____ 15. The inflammatory response is the body’s first line of defense.
____ 16. Neutrophils are involved in activation of the adaptive immune system.
____ 17. Several bacteria, such as Mycobacterium tuberculosis, are resistant to killing by granulocytes and can survive inside macrophages.
____ 18. Resolution is best defined as the restoration of original structure
