Which of the following is true of the steps of glycolysis which yield pyruvate as the end product?   a) They all occur in the cytoplasm. b) They all occur in the mitochondria. c) They occur primarily in the mitochondria. d) They occur primarily in the cytoplasm.

Name a pathway in muscles tissue that you would expect is enhanced (or upregulated) by the presence of adrenaline (aka epinephrine) in your veins (and arteries). a) glycogen breakdown b) glycolysis c) citric acid cycle/Kreb's cycle d) lipid synthesis e) beta oxidation

In the Alanine Cycle, different organs work together to produce glucose from protein.  Which statement below best describes what happens in which organ? a)In liver, pyruvate is transaminated to alanine; in the muscle, alanine is deaminated and pyruvate is used for ATP synthesis. b)In muscle, pyruvate is transaminated to alanine; in the liver, alanine is deaminated and pyruvate is used for gluconeogenesis. c)The liver exports glucose for use by the brain; in the muscle, alanine is deaminated by the urea cycle for use in ATP generation. d)In muscle, pyruvate is transaminated to alanine; in the liver, alanine enters the urea cycle for excretion.

two of the reduced electron carriers in the citric acid cycle come directly from a) isomerization of citrate b) lactic acid fermentation under anaerobic conditions c) condensation of acetate to form long-chain fatty acid  d) oxidative decarboxylations  e) succinate dehydrogenase reaction
