5 Matching questions

  1. pyruvate to acetyl-coa
  2. step 6
  3. step 8
  4. NAD+
  5. isocitrate
  1. a malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
  2. b succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2
  3. c a 2-electron oxidizing agent that is reduced to NADH; comes from nicatinamide, or niacin
  4. d a secondary alcohol that is oxidized to a ketone (alpha-kg)
  5. e pyruvate + NAD+ + CoA-SH (coenzyme A) ----pyruvate dehydrogenase complex---> CH3C(=O)SCoA (acetyl coa) + NADH + CO2

5 Multiple choice questions

  1. pyruvate, fats, amino acids, ketone bodies
  2. 4 (3 within, 1 outside)
  3. fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O
  4. it's normous and requires pantothenic acid, a water soluble vitamin, to make it
  5. flavin adenine dinucleotide, a biological oxidizing agent that is reduced to FADH2; comes from riboflavin

5 True/False questions

  1. step 5succinyl 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

          

  2. step 4alpha-ketoglutarate (5c) is oxidized to form succinyl coA (4c) with the help of alpha-ketoglurate dehydrogenase complex, transforming NAD+ into NADH, bringing in CoA, and releasing CO2 and H+

          

  3. what kinds of things inhibit the enzymes at the control points?ATP, NADH, succinyl CoA

          

  4. what can Acetyl-CoA be turned into?pyruvate, fats, amino acids, ketone bodies

          

  5. to break down 1 glucose molecule you need ___ NAD+ from inside & ____ NAD+ from outside mitochondria, ___ oxaloacetate, _____ ADP, and ____ of each enzymeit's normous and requires pantothenic acid, a water soluble vitamin, to make it
