- what can Acetyl-CoA be turned into?
- what do you need to know about pyruvate dehydrogenase complex?
- what do you need to know about CoA?
- step 4
- NAD+ vs. NAD: which is the better oxidizing agent? reducing agent?
- a alpha-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+
- b fats, ketone bodies, cholesterol (NOT glucose!)
- c FAD, NAD+
- d 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
- e it's normous and requires pantothenic acid, a water soluble vitamin, to make it
5 Multiple choice questions
- malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
- succinate (4c) is oxidized into fumarate (4c) with the help of succinate dehydrogenase, transforming FAD into FADH2
- pyruvate, fats, amino acids, ketone bodies
- inner mitochondrial matrix
- 8 (2 from pyruvate to acetyl coa, 6 from krebs), 2 (glycolysis), 1, 4, 1
5 True/False questions
step 3 → malate (4c) is oxidized into oxaloacetate with the help of malate dehydrogenase, transforming NAD+ into NADH and releasing H+
step 7 → fumarate (4c) is transformed into malate (4c) with the help of fumarase, bringing in 1 molecule of H2O
NAD+ → a 2-electron oxidizing agent that is reduced to NADH; comes from nicatinamide, or niacin
what is citrate? → a secondary alcohol that is oxidized to a ketone (alpha-kg)
what kinds of things inhibit the enzymes at the control points? → pyruvate, fats, amino acids, ketone bodies
