I’m not too sure what you mean by “aneorobic environment” but alcohol is produced by alcoholic fermentation. Lactic acid is produced in lactic acid fermentation, but they both start off with glycolysis because the whole point of fermentation is basically to produce oxygen when your body can’t inhale enough.
Answer:
A good example happens during the breakdown of food particles.
Explanation:
The chemical energy stored in food is a type of potential energy. Transformation of this energy into kinetic energy happens during chemical reactions that takes place during digestion. A good example of kinetic energy is therefore the breakdown of carbohydrates into carbon dioxide, water and heat.
