metabolic cycle    location pro/ eukaryote   components substrates products pathway purpose embden- meyerhof- parnas (glycolysis) cytoplasm/ cytoplasm 10 enzymes pentose phosphate pathway cytoplasm/ cytoplasm   

dozen enzyme

1 Glucose (6 carbon), 1 NADP, 1ATP 1 Ribose-P (5 carbon) + 1CO2, 1NADPH, or sugars, 1 ADP Nucleotide synthesis, NADPH for anabolism PDH reaction

cytoplasm/ mitochondria matrix

TCA/ Krebs/ citric acid cycle generation of high energy electron carriers, provide metabolic precursors Electron transport chain + ATP synthase (aerobic respiration) Electron transport chain + ATP synthase (anaerobic respiration) 1Nitrate or sulfate or CO2, 1NADH + ____ ADP Or 1FADH2+ ____ ADP N2, or NO2 or H2S or CH4 1NAD + ____ ATP Or 1FADH2+ ____ ATP Generate proton motive forces abd use to generate ATP regenerate NAD+ Fermentation cytoplasm/ cytoplasm 1 or more enzymes (vary by organism) 1 pyruvate, 1 NADH 1 alcohol or acid (maybe 1 CO2) NAD+ Regenerate NAD+

Explanation / Answer

1. Embden pathway have glycolysis as substrate and product is 2 molecules of puyrate. This pathway helps in breaking of glucose so that energy can be produced in cells.

2. Already done

3. PDH or puyravate dehydrogenation reaction occur in mitochondria matrix. It is consist of three enzymes. Substrate is puryate and product is acetyl CoA. The purpose is to produce acetyl CoA.

4. Krebs cycle takes place in mitochondria matrix . Consist of 8 enzymes. Substrate is acetyl CoA and oxaliacetate. Purpose is to breakdown of acetyl CoA.

5. Electron transport chain takes place in inner mitochondrial membrane. .Substrate is NAD+ and FAD. The product is H2O. The product is transport of electrons in sequential manner to produce water.
