1) The first cycle is a Entner-Doudorof pathway.
2) The second cycle is the Embden-Meyerhof pathway.
3) The third cycle is the pentose phosphate pathway.
In the pentose phosphate pathway, 6-phosphogluconate is decarboxylated and several intermediates enter the Embden-Meyerhof pathway.
The glyceraldehyde-3-P produced via 6-phosphogluconate is further oxidized by the Embden-Meyerhof pathway.
In the process of glycolysis/ Entner-Doudorof pathway, glyceraldehyde-3-P formed in pentose phosphate pathway and Embden-Meyerhof pathway is oxidized to pyruvate by various enzymes.
Drag and drop each pathway descriptor to distinguish the glycolytic pathways below, then characterize each pathway...

Breakdown of pyruvate Breakdown of precursor metabolites Production of ATP Production of precursor metabolites Catabolize glucose to pyruvate Production of NAD Production of ADP Production of NADH
7. Rat liver can metabolize glucose by both the glycolytic and the pentose phosphate pathways. Indicate in the box if the following are properties of glycolytic (G), pentose phosphate (P), both (G+P), or neither (O): (5 marks) a) NAD+ is involved b) CO2 is liberated c) Phosphate esters are intermediates d) Glyceraldehyde 3-phosphate is an intermediate e) Fructose 6-phosphate is an intermediate
Metabolic Pathway Engineering Problem Set 5 Engineering a Fermentation System: Fermentation of plant matter to produce ethanol for fuel is one potential method for reducing the use of fossil fuels and thus the CO2 emissions that lead to global warming. Many microorganisms can break down cellulose then ferment the glucose to ethanol. However, many potential cellulose sources, including agricultural residues and switchgrass, also contain substantial amounts of arabinose, which is not as easily fermented. Escherichia coli is capable of fermenting...
