In glycolysis, glucose molecule is converted into pyruvate molecules .

It can't be cellular respiration because it starts always with glucose i.e glycolysis. But here it is the process after glycolysis (starting from pyruvate) and changing into lactic acid. It's an aerobic respiration called as lactic acid fermentation.

Fermentation

Answer:

The correct answer is Glycolysis. The answer above is incorrect, because it is asking for what happens BEFORE the process depicted below, not what the process is. I'm not sure why it is verified, but whatever...

Explanation:

This is because the process shown in the diagram would have been the Krebs Cycle, in which glycolysis would have to occur before for it to work.

Also, I did this question on an assignment recently. Fermentation was incorrect.
