The anaerobic phase of cellular respiration, also known as glycolysis, produces 2 molecules of pyruvate.

However, it's important to note that this is not the only product. Glycolysis also produces:

* 2 molecules of ATP (adenosine triphosphate)

* 2 molecules of NADH (nicotinamide adenine dinucleotide)

While pyruvate is the main product that moves on to the aerobic phase, the ATP and NADH generated during glycolysis are crucial for energy production in the cell.
