Research Question: How does increasing the concentration (1%, 3%, 5%) of amylase from the pancreas affect the rate of the breakdown of starch solution, measured by the time taken for the starch to turn into simple sugars using a stopwatch (0.01s) Personal Engagement: The reason why I chose to do concentration was because I found it to be the most interesting out of all the options. I wanted to learn about how both enzyme and substrate concentrations affect the rate of reaction. Learning about enzyme concentration is not of any significance to me, and I chose it just out of curiosity. *Background Information: Enzymes act as catalysts to kickstart and speedup the rate of reaction without being used up. Their use is vital for life as they work in important parts of the body. The reactions that enzymes catalyze include digestion and metabolism. All enzymes of made of proteins.They are folded into complicated shapes in order to allow smaller molecules (substrate) to fit into them. The place at which the enzyme and substrate combine is called the active site. There are several factors affecting enzyme activity. These are temperature, pH, enzyme and substrate concentration, enzyme:substrate ratio, and surface area. Increasing the temperature increases the kinetic energy needed to kickstart the reaction. In a liquid substance, this means that there are more random collisions between the molecules. Because increasing the temperature speeds up the rate of reaction, more
