5 Matching questions

  1. what do you need to know about pyruvate dehydrogenase complex?
  2. which intermediates of the krebs cycle can be made into glucose?
  3. step 5
  4. FAD
  5. what can Acetyl-CoA be turned into?
  1. a all of them
  2. b its coenzymes include b-vitamins (water soluble) that act as recyclable prosthetic groups; it's the most irreversible reaction in our body/there's no getting around it, so once acetyl-CoA is made, you cannot go back
  3. c fats, ketone bodies, cholesterol (NOT glucose!)
  4. d flavin adenine dinucleotide, a biological oxidizing agent that is reduced to FADH2; comes from riboflavin
  5. e succinyl CoA (4c) is transformed into succinate (4c) with the help of succinyl CoA synthetase, transforming GDP + Pi into GTP with the energy released from the C-S bond

5 Multiple choice questions

  1. oxaloacetate (4c) is condensed with an acetyl group (2c) to form citrate (6c) with the help of citrate synthase
  2. pyruvate, fats, amino acids, ketone bodies
  3. 4 (3 within, 1 outside)
  4. a secondary alcohol that is oxidized to a ketone (alpha-kg)
  5. citrate (6c) is isomerized to isocitrate (6c) with the help of aconitase

5 True/False questions

  1. what is citrate?a secondary alcohol that is oxidized to a ketone (alpha-kg)


  2. step 8malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+


  3. step 7succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2


  4. step 6fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O


  5. what do you need to know about CoA?it's normous and requires pantothenic acid, a water soluble vitamin, to make it
