5 Matching questions

  1. pyruvate to acetyl-coa
  2. step 6
  3. step 7
  4. FAD
  5. step 8
  1. a malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
  2. b pyruvate + NAD+ + CoA-SH (coenzyme A) ----pyruvate dehydrogenase complex---> CH3C(=O)SCoA (acetyl coa) + NADH + CO2
  3. c fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O
  4. d flavin adenine dinucleotide, a biological oxidizing agent that is reduced to FADH2; comes from riboflavin
  5. e succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2

5 Multiple choice questions

  1. ATP, NADH, succinyl CoA
  2. isocitrate (6c) is oxidized to form alpha-ketoglutarate (5c) with the help of isocitrate dehydrogenase, transforming NAD+ into NADH and releasing H+ and CO2
  3. the conjugate base of citric acid; a tertiary ROH that is not easily oxidized (that's why it's isomerized in the cycle)
  4. it's normous and requires pantothenic acid, a water soluble vitamin, to make it
  5. fats, ketone bodies, cholesterol (NOT glucose!)

5 True/False questions

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

          

  2. where does it take place?inner mitochondrial matrix

          

  3. NAD+a 2-electron oxidizing agent that is reduced to NADH; comes from nicatinamide, or niacin

          

  4. to break down 1 glucose molecule you need ___ NAD+ from inside & ____ NAD+ from outside mitochondria, ___ oxaloacetate, _____ ADP, and ____ of each enzyme8 (2 from pyruvate to acetyl coa, 6 from krebs), 2 (glycolysis), 1, 4, 1

          

  5. step 4oxaloacetate (4c) is condensed with an acetyl group (2c) to form citrate (6c) with the help of citrate synthase
