Quiz zum Vortrag

  1. They are made by de novo and salvage pathways.
  2. They are made in separate, non-overlapping pathways for each nucleotide.
  3. They can have any of three purines or two pyrimidines.
  4. Structurally, pyrimidines have two rings, and purines have one.
  5. They are the building blocks of DNA and RNA.
  1. All of the answers are true.
  2. PRPP synthetase catalyzes the process that converts ATP to AMP.
  3. It begins with ribose-5-phosphate.
  4. It includes the intermediate known as IMP.
  5. It consumes ATP.
  1. Gluteraldehyde
  2. Glycine and glutamine
  3. CO2
  4. Aspartate
  5. N10-formyl-THF
  1. N10-formyl-THF — source of N atoms in purine synthesis
  2. Ribose-5-phosphate — starting point
  3. Inosine monophosphate — branch point between ATP and GTP synthesis
  4. PRPP synthetase — regulatory enzyme for purine synthesis
  5. PRPP amidotransferase — helpful in synthesis of phosphoribosylamine

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were
