Catabolic Pathways and Fermentation

This metabolic pathway occurs in the cytoplasm of the cell, is anaerobic and involves the splitting of a six-carbon sugar into two three-carbon intermediates.

Why is the real net gain in ATP by a cell only two following glycolysis, though four ATP were generated during this pathway?

How many ATP molecules are generated during the decarboxylation of pyruvic acid?

Following decarboxylation and the two Krebs Cycle reactions, how many molecules of CO2 have been removed from the original glucose molecule?

During each turn of the Krebs Cycle, how many reduced molecules of NADH+ H⁺ are generated?

The accumulation of hydrogen ions between the cristae and outer membrane of the mitochondrion builds _________ which drives the hydrogen through ATP synthase.

Which final hydrogen and electron acceptor allows a cell to generate the most ATP?

How many ATP molecules are generated by substrate-level phosphorylation during the two turns of the Krebs Cycle from each original glucose molecule?

The two-carbon molecules released from fatty acids during lipid catabolism

Far less ATP is generated during fermentation than oxidative phosphorylation since
