Question

Additional Metabolic Pathways
For each of the reactions or products given choose the metabolic pathway or pathways where that reaction occurs or the product is made.
The topics for this problem are alternatives to glycolysis, catabolism of lipids and proteins and anabolic pathways.
Some responses may be used more than once while others may not be used at all.
For each part of the question choose the best or most complete response.
Responding choice:

1.amination 2.trans-amination 3.beta-oxidation 4.Calvin-Benson cycle

5.Entner-Doudoroff pathway 6. fermentation 7. gluconeogenesis 8. pentose-phosphate pathway

Question:

1. a six carbon sugar like glucose is converted to a 5 carbon sugar like ribose-5-phosphate and CO2

2. glutamic acid + pyruvate yields alpha-ketoglutarate + alanine
3. long fatty acid chains are broken down to two carbon units, forming acetyl-CoA
4. 2 ATPs are made when glucose is partially oxidized to pyruvate and then the pyrruvate is reduced to lactic acid

Explanation / Answer

1. a six carbon sugar like glucose is converted to a 5 carbon sugar like ribose-5-phosphate and CO2 :pentose phosphate pathway

2. glutamic acid + pyruvate yields alpha-ketoglutarate + alanine :trans -amination
3. long fatty acid chains are broken down to two carbon units, forming acetyl-CoA : beta oxidation
4. 2 ATPs are made when glucose is partially oxidized to pyruvate and then the pyrruvate is reduced to lactic acid :Fermentation
