Terms in this set (101)
Glycolysis:
- 2 ATP
- 2 NADH (cytoplasm) = 3 ATP
Pyruvate DH
ATP Counting - 2 NADH (mito) = 5 ATP
TCA (x2 from 1 glucose)
- 3 NADH (mito) = 15 ATP
- 1 FADH2 = 3 ATP
- 1 GTP = 2 ATP
1. Pyruvate + TPP
2. TPP + lipoamide
Pyruvate Dehydrogenase
3. CoA + lipoamide = acetyl CoA
4. renerate lipoamide + NADH
Chelates to lipoamide
Mercury and Arsenic Poisoning to remove put in stronger chelating agent so mercury doesnt bind

, 1. Phosphorylate PDH inactivates
Regulation of PDH
(high ATP - dont want cycle turned on)
Citrate (Aconitase)
Isocitrate (Isocitrate DH)
a - Ketoglutarate (a-Ketoglutarate DH complex)
Succinyl CoA (Succincyl CoA synthetase)
TCA Cycle
Succinate (Succinate DH)
Fumarate (Fumarase)
Malate (Malate DH)
Oxaloacetate (Citrate Synthase)
1. Hypoxia induced factor I - low O2 levels and therefore harder to get into glycolysis
2. Enzyme deficiencies - need for SDH and PDH
Diseases of TCA cycle
3. Beriberi - thiamine deficiency = bone deformities
4. Mercury and Arsenic - chelaters for dihyrdolipoamides
- Isocitrate --> a-Ketoglutarate
Regulation points ATP and NADH regulate this cycle if present
ADP regulates by being absent
citrate --> fatty acids and steroids
a-Ketoglutarate --> glutamate and amino acids
Branching off
Succinyl CoA --> porphorins
Oxaloacetate --> amino acids, glucose
Support plants to live off fat and oil from storage
convert succinate into glucose
not as efficient
Glyoxylate cycle /Use acetate --> acetyl CoA no glycolysis
/succinate&oxaloacetate --> glucose
/through gluconeogenesis = 2 Acetyl CoA = 1 NADH
/isocitrate lyase --> glyoxylate --> Malate synthase
Delta G Change in gibbs free energy
Eo Electron transfer potential
