Why is it possible for potassium to diffuse easily into and out of cells? The resting plasma membrane is more permeable to potassium. A major determinant of the resting membrane potential necessary for the transmission of nerve impulses is the ratio between: Intracellular and extracellular K+ What is a consequence of plasma membrane damage to the mitochondria? Influx of calcium ions halts ATP production. Current research supports the belief that after heart muscle injury, the damage: Is repaired by newly matured cardiomyocytes Free radicals cause cell damage by: Giving up an electron, which causes injury to the chemical bonds of the cell membrane The loss of the ATP during ischemia causes cells to: Swell because of the influx of sodium chloride (NaCl) Which statement is true about eukaryotic cells?
They contain compartments called organelles. Which mode of chemical signaling uses local chemical mediators that are quickly taken up, destroyed, or immobilized? During cell injury caused by hypoxia, an increase in the osmotic pressure occurs within the cell because: Quiz 2 Question 4 . Sodium chloride enters the cell. When a mucous gland cell creates a new substance from previously absorbed material, this process is known as which specialized cellular function? Question : A reduction in an individual’s number of NK cells appears to correlate with an increased risk for the development of: Student Answer: Depression Question 6 . Question : Which statement concerning exotoxins is true? Exotoxins are released during bacterial growth. Question 7 . Question : Which statements are true regarding viruses? (Select all that apply.) Viruses are referred to as eukaryotes. Viruses are capable of producing messenger ribonucleic acid RNA (mRNA).
IL- 2

Women who have a high body mass index (BMI) A carcinoma refers to abnormal cell proliferation originating from which tissue? Epithelial cells The ras gene converts from a proto-oncogene to an oncogene by: Altering one or more nucleotide base pairs Which statement concerning benign tumors is true****? The cells are well differentiated. Which aberrant change causes the abnormal growth in a
retinoblastoma? The tumor suppressor gene is turned off. Which cancers pose the highest risk for radiologists?

Once the placenta is removed from circulation Which inflammatory cytokines are released when endothelial cells are injured? Tumor necrosis factor–alpha (TNF-α), interferon-gamma (IFN-γ), and interleukin 1 (IL-1) Which statement is true concerning the cells’ ability to synthesize cholesterol? Most body cells are capable of producing cholesterol.
What is the usual source of pulmonary emboli? Deep venous thrombosis Amyloidosis, hemochromatosis, or glycogen storage disease usually causes which form of cardiomyopathy? Restrictive Which condition is consistent with the cardiac defect of transposition of the great vessels? The aorta arises from the right ventricle. Quiz 5 : Which statement is true regarding hypoxemia? Respiratory alterations cause hypoxemia.

What is an example of compensatory hyperplasia? Student Answer: Hepatic cells increase cell division after part of the liver is excised. Question : Which is an example of an endogenous antigen? Cancer cells Which factor contributes to the production of mucus associated with chronic bronchitis? Increased goblet cell size Which type of cell adaptation occurs when normal columnar ciliated epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells? Metaplasia Some older adults have impaired inflammation and wound healing because of which problem? Underlying chronic illnesses exist.
Which statement is true for the process of cellular reproduction? Two diploid cells, called daughter cells , have been formed. : During an Immunoglobulin E (IgE)-mediated hypersensitivity reaction, the degranulation of mast cells is a result of which receptor action? Histamine bound to H 2 Vaccines against viruses are created from: Live organisms weakened to produce antigens Why is osmolality preferred over osmolarity as the measurement of osmotic activity in the clinical assessment of individuals? More of the weight of plasma is influenced by solutes, such as protein and glucose, rather than by water. In addition to osmosis, what force is involved in the movement of water between the plasma and interstitial fluid spaces? Hydrostatic pressure
