5 Matching questions

  1. NAD+
  2. what kinds of things inhibit the enzymes at the control points?
  3. what can Acetyl-CoA be turned into?
  4. step 3
  5. there are ___ control points
  1. a fats, ketone bodies, cholesterol (NOT glucose!)
  2. b a 2-electron oxidizing agent that is reduced to NADH; comes from nicatinamide, or niacin
  3. c 4 (3 within, 1 outside)
  4. d isocitrate (6c) is oxidized to form alpha-ketoglutarate (5c) with the help of isocitrate dehydrogenase, transforming NAD+ into NADH and releasing H+ and CO2
  5. e ATP, NADH, succinyl CoA

5 Multiple choice questions

  1. FAD, NAD+
  2. 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
  3. oxaloacetate (4c) is condensed with an acetyl group (2c) to form citrate (6c) with the help of citrate synthase
  4. pyruvate + NAD+ + CoA-SH (coenzyme A) ----pyruvate dehydrogenase complex---> CH3C(=O)SCoA (acetyl coa) + NADH + CO2
  5. fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O

5 True/False questions

  1. step 6succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2


  2. step 2citrate (6c) is isomerized to isocitrate (6c) with the help of aconitase


  3. which intermediates of the krebs cycle can be made into glucose?fats, ketone bodies, cholesterol (NOT glucose!)


  4. what is citrate?the conjugate base of citric acid; a tertiary ROH that is not easily oxidized (that's why it's isomerized in the cycle)


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