UNE medical biochemistry Unit 2 Test

UNE medical biochemistry Unit 2 Test If unregulated, which of the following pairs of enzymes would represent a futile cycle? Fructose 1,6 bisphosphatase and phosphofructokinase-1 Rotenone blocks complex 1 in the ETC. This increases levels of NADH and would likely impair the function of which of the following enzymes? Pyruvate dehydrogenase complex Newborn screening shows a biotinidase deficiency in a 2-day old infant. This deficienty impairs the infant's ability to reuse and recycle biotin. Due to this enzymatic deficiency, the activity of which of the following enzymes is likely impaired? pyruvate carboxylase An individual is recently diagnosed with Type 2 diabetes. In this individual, hyperglycemia may in part be due to inactivity of which of the following glucose transporters on skeletal muscle? Glut 4 (insulin dependent) The skeletal muscle primarily provides substrate for gluconeogenesis through which of the following processes? protein catabolism Alanine can be shuttled from the skeletal muscle to the liver where it is deaminated to produce pyruvate. When glucagon is high, pyruvate is primarily used as a substrate for which of the following pathways? gluconeogenesis Aldolase B facilitaes a reaction that cleaves fructose 1-phosphate into two 3-carbon molecules that will enter glycolysis as which of the following compounds? glyceraldehyde-3-p
