When oxygen is not available, glycolysis produces lactate as its byproduct.Option A is correct.
What is glycolysis?
A process through which cells partially break down glucose via oxygen-free enzyme activities. One process that cells employ to make energy is glycolysis.
The breakdown of glucose can occur more completely and more energy can be created when glycolysis is combined with other enzyme activities that require oxygen.
Pyruvate, the last result of glycolysis, is fermented to produce lactic acid, ethanol, and CO₂ in the absence of oxygen. Anaerobic respiration is the term for it.
Lactate is the end product of glycolysis when oxygen is not present.
Hence, option A is correct.
