During a bread making process glucose is converted to ethanol and carbon dioxide causing the bread dough to rise by itself this process takes longer than a human life span however when zymase an nzyme produced by yeast is added to bread the bread will ride in 15-20 min what is the function of zymase

Zymase is acting as a catalyst

Explanation:

Zymase is an enzyme that is naturally produced in yeast. Enzymes are biological catalysts that speed up the rates of reactions in living things.

Zymase catalyses the breakdown of glucose into ethanol and carbon dioxide, which causes the bread to rise.

Zymase speeds up this reaction, but is not physically changed itself. Therefore, it is a catalyst.

Actually, zymase represents a collection of enzymes in yeast, not just one!

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
