WHAT IS THE EXPERIMENT ABOUT?
This experiment is about the enzyme Rennin. Rennin is an enzyme, which is present in the stomach. The experiment is about the effects of temperature on the enzyme activity of rennin.
BACKGROUND INFORMATION
Enzymes are proteins that control vital biological processes. They often act as biological catalysts. In the human body enzymes control the breakdown of food and reactions, which make DNA and proteins. These include baking, cheese making and treating leather. Enzymes are also used in Biological Washing powders. Enzymes are sometimes in industries such as:
Amylase
Stain removal, paper manufacturer, making syrups
Lipases
Speeding up the ripening of cheese
Proteases
Stain removal, making biscuit flour
Catalase
Preservative in soft drinks, rubber manufacture
Enzymes are also useful chemical tools. Microorganisms are usually grown for their enzymes so they can be extracted.
As you know enzymes are present in the digestive system. Some enzymes involved in digestion are amylase, maltase, protease and lipease. They break down starch, glucose, proteins, and fat into glucose, amino acids, fatty acids and glycerol. But because enzymes are proteins they affected by pH and temperature.
Enzymes are a bit like a jigsaw puzzle because they will only fit together with only one certain reactant. Only one substrate can fit into one active site. When the enzyme molecule and reactant molecule fit together, a reaction will take place.
Summary of enzyme reaction
Rennin
The enzyme rennin works just like as above, accept the active site of rennin will only accept the substrate of milk molecule. Rennin breaks down and curdles milk just like the way bile emulsifies fats. It is found in the stomach and its reactant is milk protein and water.
The rate of a reaction increases with temperature because particles come into contact more often due to the fact they are moving faster and the enzymes will have more activation energy.
