Millions of chemical reactions take place during daily life processes every second. Interestingly, enzymes act as vital catalysts that could speed up the chemical reactions by thousands or even millions of times.
In the absence of these enzymes, some biochemical reactions inside living organisms might happen with a very slow rate, while others would not have taken place at the normal temperatures.
For example, the digestion process aims to break down or digest foods represented in building a model for catalytic interactions experiment by biscuits by the action of stomach acid represented here by soft drink such as seven up.
