12. The bubbling that you observed indicated the production of what gas as a result of the enzymatic

reaction?

As a result of enzymatic reaction bubbles of oxygen gas are produced in the form of foam

Explanation:

Living Cells produced an enzyme called catalase. The enzyme catalase breakdown hydrogen peroxide. This is well understood by an equation

2 H2O2 catalase 2 H2O + O2+

In a solution the enzyme catalase activity can be measured by the production of Oxygen gas bubbles out in the form of foam. When H2O2 added in a catalase solution and leave it for certain time period, the foam height rises in the test tube, it can be measured. The greater the foam height the enzyme catalase activity will also be greater.
