Metabolism Podcast - TCA Podcast Flashcards
What does NAD stand for?
Nicotinamide Adenine Dinucleotide.
During Glycolysis how much Nicotinamide Adenine Dinucleotide is formed?
2 NADH+ + 2 H+
What is the fate of Pyruvate?
Lactic Acid formation
Citric Acid Cycle/ Krebs Cycle
What is the enzyme used for anaerobic respiration in humans?
Lactate dehydrogenase
Where does the TCA cycle occur?
In the Mitochondria
In the central matrix
What occurs in the link reaction between Glycolysis and Krebs cycle/ TCA cycle?
A Pyruvate molecule is converted into Acetyl-CoA via a Pyruvate dehydrogenase complex
- Decarboxylation, CO2 evolved
What occurs in the TCA cycle?
Acetyle- Co A(2c) joins with Oxaloacetate molecule (4c)
Form Citric Acid (6c)
Citrate is then decarboxylated twice to give off 2 CO2 molecules
What is produced from the TCA cycle?
4 pairs of electrons
3 pairs of electrons accepted by NAD+
1 pair of electrons accepted by FAD
1 GTP produced
What are the molecules formed in the Krebs cycle?
Acetyle Co A (2c) + Oxaloacetate (4c)
Citrate 6c
Alpha Ketoglutarate 5c
Succinate (4c)
Fumerate (4c)
Malate (4c)
Oxaloacetate (4c)
During anaerobic respiration what is depleted?
NADH depleted
Regeneration of NAD
