5 Multiple Choice Questions
- citrate (6c) is isomerized to isocitrate (6c) with the help of aconitase
- 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
- the conjugate base of citric acid; a tertiary ROH that is not easily oxidized (that's why it's isomerized in the cycle)
- a 2-electron oxidizing agent that is reduced to NADH; comes from nicatinamide, or niacin
- pyruvate, fats, amino acids, ketone bodies
5 True/False Questions
step 8 → malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
where does it take place? → inner mitochondrial matrix
FAD → flavin adenine dinucleotide, a biological oxidizing agent that is reduced to FADH2; comes from riboflavin
there are ___ control points → inner mitochondrial matrix
step 7 → oxaloacetate (4c) is condensed with an acetyl group (2c) to form citrate (6c) with the help of citrate synthase
