Brown and Goldstein won the Nobel Prize for discovering the molecular basis of familial hypercholesterolemia (FH).  The key experiment that led to the breakthrough was that cells from FH patients responded to LDL by increasing cholesterol biosynthesis.   True or False

Increased gas production in the rumen b.   Impaired vision   c.   Decreased ATP synthesis   d.    Increased osmotic water influx into the lumen of the small intestine   e.   Increased serum cholesterol in the blood

When transaminated, the three branched-chain amino acids (valine, leucine, and isoleucine) form compounds that have the characteristic odor of maple syrup. An enzyme known as branched-chain a-keto acid dehydrogenase converts these compounds into CoA esters. People who do not have this enzyme have the genetic disease known as maple syrup urine disease, so called because their urine smells like maple syrup. a. Draw the compounds that smell like maple syrup.b. Draw the CoA esters.c. Branched-chain a-keto acid dehydrogenase has five coenzymes. Identify them.d. Suggest a way to treat maple syrup urine disease.

Which one of the following are correctly paired?   a.   glycogen synthesis: catabolic   b.   Glycogenolysis: catabolic   c.   Glycolysis: anabolic   d.   Gluconeogenesis: catabolic   e.   TCA cycle: anabolic

Which of the following statements is/are TRUE about the PPP?   A. Most active in cells where lipids are synthesized. B. Reactions involved are oxidative and non-oxidative. C. Also called the hexose monophosphate shunt pathway. D. Occurs in the cytosol.

The glycolytic enzyme glucokinase (in human liver cells) catalyzes the conversion of: glyceraldehyde-3-phosphate into 1,3-bisphosphoglycerate (producing NADH) phosphoenolpyruvate into pyruvate (producing ATP) fructose-6-phosphate into fructose-1,6-bisphosphate (consuming ATP) glucose into glucose-6-phosphate (consuming ATP) 1,3-bisphosphoglycerate into 3-phosphoglycerate (producing ATP)
