Question

Diagram an enzyme at work and label the parts; explain how the enzyme is helping the reaction proceed; what is/are the substrates and products; what type of reaction to this; and what factors can modify this reaction and how (what is the effect of the modification)?

The above diagram shows enzyme at work.

Substrate (here, sucrose) binds with the active sites of the enzyme (sucrase) to produce a temporary molecule, enzyme substrate complex. Soon, the enzyme converted the substrate into products. Then the products separate from enzyme without any change in the shape of enzyme.

The substrate is sucrose and the products are glucose and fructose. This is an example of an enzymatic hydrolysis reaction. Because, sucrose is converted into glucose and fructose by eliminating a water molecule.

Temperature, concentration of enzyme , concentration of substrate, pH and the presence of any activators and inhibitors effect enzyme action. These factors can modify the enzymatic reaction. Enzyme is active only in optimum temprature and optimum pH. Presence of inhibitors, inhibits the enzymatic reaction and the activators activates the reaction. Increasing concentration of substrates and enzymes increases the reaction rate. The decreasing amount of substrate and enzyme decreases the rate of reaction.
