physiologic jaundice - A 3-day old infant is noted to have a mildly elevated unconjugated bilirubin level and icterus. Your concern is that this child may have: a. physiologic jaundice b. kernicterus c. glucose-6-phosphate dehydrogenase deficiency d. pathologic jaundice Lysosomes - Which cell component is capable of cellular autodigestion when it is released during cell injury? a. lysosomes b. ribosomesc. smooth endoplasmi c reticulum d. golgi complex Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction? A) lysosomes B) peroxisomes C) ribosomes D) oxyhydrosomes - Ans: B- peroxisomes Contain organelles and complex internal membranes - The difference between eukaryotes and prokaryotes is that eukaryotes: a. all of these answers are correct b. are smaller in size c. contain organelles d. have no nuclear membrane What is a consequence of plasma membrane damage to the mitochondria? A) enzymatic digestion halts deoxyribonucleic acid (DNA) synthese B) influx of calcium ions halts adenosine triphosphate (ATP) production C) edema from an influx in sodium causes a reduction in ATP production D) potassium shifts out of the mitochondria, which destroys the infrastructure - Ans: B- influx of calcium ions halts adenosine triphosphate (ATP) production Packages protein for secretion to the outside of the cell - Which of the following is function of Golgi? a. Packages protein for secretion to the outside of the cell b. Produces ATP for cell function c. Contains hydrolytic enzymes d. Is the site of protein synthesis in a cell Which statement is a description of one of the characteristics of apoptosis? A) apoptosis involves programmed cell death of scattered singel cells B) apoptosis is characterized by the swelling of the nucleus and the cytoplasm C) apoptosis involves unpredictable patterns of cell death D) apoptosis results in benign malignancies - Ans: A- apoptosis involves programmed cell death of scattered singel cells During cell injury caused by hypoxia, sodium and water move into the cell because: A) during cell injury cause by hypoxia, sodium and water move into the cell because: B) the pump that transports sodium out of the cell cannot function because of a decrease in adenosine triphosphate (ATP) levels C) the osmotic pressure is increased, which pulls additional sodium across the cell membrane D) oxygen is not available to bind with sodium to maintain it outside of the cell - Ans: C- the osmotic pressure is increased, which pulls additional sodium across the cell membrane
