Answer:
The correct answer is anaerobic process that breaks down glucose.
Step-by-step explanation:
Glycolysis helps in the catabolism or breakdown of glucose into pyruvate.The glycolysis process does not requires oxygen to proceed it simply means glycolysis occur in absence of oxygen.
The cellular respiration will be aerobic or anaerobic depending on the reaction carried out by the pyruvate.
If the pyruvate is converted to acetyl CoA then the process is aerobic respiration but if the pyruvate is converted to either lactate or ethanol then the process is called anaerobic respiration.
