  • Question 1 - Major supplies of glycogen are found in …. ...

    Correct

    • Major supplies of glycogen are found in ….

      Your Answer: Liver and skeletal muscle

      Explanation:

      The two major sites of glycogen storage are the liver and skeletal muscle. The concentration of glycogen is higher in the liver than in muscle however more glycogen is stored in skeletal muscle due to its greater mass.

    Correct

    • Nucleic acids are split into nucleotides in the:

      Your Answer: Intestine

      Explanation:

      The pancreas is the major source for all the digestive enzymes including nucleases which split nucleic acids into nucleotides primarily in the small intestine.

    Correct

    • During anaerobic glycolysis, the net production of ATP is:

      Your Answer: 2

      Explanation:

      Anaerobic glycolysis is the transformation of glucose to lactate when limited amounts of oxygen (O2) are available. Anaerobic glycolysis is only an effective means of energy production during short, intense exercise, providing energy for a period ranging from 10 seconds to 2 minutes. It produces 2 ATP molecules per glucose molecule.

    Correct

    • The largest energy reserves among both lean and obese subjects are from?

      Your Answer: Fatty acids

      Explanation:

      The energy required for sustained exercise is provided by the oxidation of two fuels, glucose stored as glycogen in the liver and muscle, and long-chain fatty acids, stored as adipose tissue triglycerides. The latter provides the largest energy reserve in the body.

  • Question 5 - Phosphorylation of glucose once it enters the cell is catalysed by which enzyme?...

    Correct

    • Phosphorylation of glucose once it enters the cell is catalysed by which enzyme?

      Your Answer: Hexokinase

      Explanation:

      Glucose 6-phosphate is produced by phosphorylation of glucose on the sixth carbon. This is catalysed by the enzyme hexokinase in most cells. One molecule of ATP is consumed in this reaction.

    Correct

    • The conversion of fructose to fructose 1-phosphate is catalysed by:

      Your Answer: Fructokinase

      Explanation:

      The first step in the metabolism of fructose is the phosphorylation of fructose to fructose 1-phosphate by fructokinase.

    Correct

    • Lipid- lowering drugs like Lovastatin reduce cholesterol synthesis by inhibiting which enzyme?

      Your Answer: HMG-CoA reductase

      Explanation:

      Statins, also known as HMG-CoA reductase inhibitors, are a class of lipid-lowering medications. Statins have been found to reduce cardiovascular disease (CVD) and mortality in those who are at high risk.

    Correct

    • The complex twisting and folding of peptide chains describes which order of protein structure?

      Your Answer: Secondary structure

      Explanation:

      Secondary Structure refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures: the alpha (α) helix and the beta (β) pleated sheet.

    Correct

    • Which enzyme hydrolyses triglycerides in lipoproteins into free fatty acids for storage in fat cells?

      Your Answer: Lipoprotein lipase

      Explanation:

      Lipoprotein lipase is a water-soluble enzyme that hydrolyses triglycerides in lipoproteins, such as those found in chylomicrons and very low-density lipoproteins (VLDL), into two free fatty acids and one monoacylglycerol molecule.

    Correct

    • The energy needed for glycogen synthesis comes from which compound?

      Your Answer: UTP

      Explanation:

      Glycogen synthesis is, unlike its breakdown, endergonic—it requires the input of energy. Energy for glycogen synthesis comes from uridine triphosphate (UTP)
