<span>Yeasts are unicellular microorganisms that use sugar as food releasing carbon dioxide. With the released gas increases the pressure when oxygen is present inside the bottle, yeasts grow by the breathing process are consuming oxygen and producing carbon dioxide. And when the oxygen is finished the yeasts change to anaerobic metabolism and the degradation of sugar occurs by fermentation that produces greater amounts of alcohol and gaseous carbon dioxide.</span>

Explanation:
Digestion or breakdown of food in our body can either be physical/mechanical or chemical/enzymatic. As rightly stated in this question, the manual breakdown of food by the teeth is not enough, chemical digestion must occur via the aid of proteinous substances called ENZYMES. Enzymes, which are secreted by certain organs in the body, do the following:
- They speed up the rate of chemical reactions by lowering the activation energy needed for the chemical process, allowing more productivity.
- Enzymes help break down various sugars that can then be absorbed e.g amylase helps break down starch, proteases break down proteins, lipases break down lipids etc.
