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-phosphate Within the RBC, NADPH is used for which of the following processes? - to re-reduce glutathione
