Glycolysis book quiz Flashcards

Q

What happens to the products of glycolysis?

A

ATP is hydrolyzed to fuel many reactions within the cell; some energy is lost as heat in the process.

The molecules of NADH serve as both energy and electron shuttles within the cell.

Glycolysis alone results in the formation of relatively small amounts of ATP and NADH compared to the citric acid cycle and oxidative phosphorylation.

Q

What happens to the pyruvate produced by glycolysis?

A

When oxygen is available, pyruvate is most often transported to the mitochondrial matrix, where it is converted to a substrate for the citric acid cycle.

In the absence of oxygen, some cells can use pyruvate as a substrate for a number of alternative pathways, most notably, lactate fermentation or alcohol fermentation.
