- what do you need to know about pyruvate dehydrogenase complex?
- which intermediates of the krebs cycle can be made into glucose?
- step 5
- what can Acetyl-CoA be turned into?
- a all of them
- 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
- c fats, ketone bodies, cholesterol (NOT glucose!)
- d flavin adenine dinucleotide, a biological oxidizing agent that is reduced to FADH2; comes from riboflavin
- 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
- oxaloacetate (4c) is condensed with an acetyl group (2c) to form citrate (6c) with the help of citrate synthase
- pyruvate, fats, amino acids, ketone bodies
- 4 (3 within, 1 outside)
- a secondary alcohol that is oxidized to a ketone (alpha-kg)
- citrate (6c) is isomerized to isocitrate (6c) with the help of aconitase
5 True/False questions
what is citrate? → a secondary alcohol that is oxidized to a ketone (alpha-kg)
step 8 → malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
step 7 → succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2
step 6 → fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O
what do you need to know about CoA? → it's normous and requires pantothenic acid, a water soluble vitamin, to make it
