Products of Metabolic Pathways

Fermentation

2 ATP per glucose

TCA Cycle

4 NADH2, 1 FADH, 1 ATP, 3 CO2 per pyruvate (multiply by 2 for per glucose)

Calvin Cycle

Fixes CO2 into glucose using Rubisco

Uses 3 ATP and 2 NADH per CO2 fixed

3 steps: Carboxylation, Reduction, Regeneration

Pentose Phosphate Pathway

produces NADPH, no pyruvate

Oxidative Phosphorylation

34 ATP

Glycolysis

2 ATP, 2 NADH, 2 Pyruvate

Anoxygenic PS I

Generates ATP and NADPH

Only produces proton motive force when H2S used

Anoxygenic PS II

Generates ATP, no NADPH

Generates proton motive force

Oxygenic Photosynthesis

Uses PS I and PS II

Generates proton motive force

Produces ATP and NADPH

Nitrogen Fixation into Ammonia

Uses Nitrogenase Enzyme

Uses 16 ATP

Utilization of Nitrate

Nitrate to Nitrite using Nitrate Reductase

Nitrite to Ammonia using Nitrite Reductase

Ammonia Assimilation

Converting Ammonia into organic molecules

GS-GOGAT system produces glutamine and glutmate using ATP and NADPH

GDH system produces glutamate using NADPH

Sulfur Metabolism

Sulfate reduced to H2S by linking sulfate covalently yo remains of ATP molecule since it is a poor electron acceptor
