Biology Lab Report Research Question: Effects of pH on amylase activity Introduction: Amylase is an enzyme that is in human’s saliva as well as the pancreas. Enzymes are biological catalysts that speed up a chemical reaction. They break down complex molecules into simple ones. In this case‚ amylase converts starches (complex molecule) into simple sugars. That is why foods like potatoes for example‚ may taste sweet to us‚ because they contain starch. The optimum pH for pancreatic

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Fluid Catalytic Cracking Fluid catalytic cracking* (FCC) is the most important conversion process used in petroleum refineries. It is widely used to convert the high-boiling hydrocarbonfractions of petroleum crude oils into more valuable [1][2][3] gasoline‚ olefinic gases and other products. . Cracking of petroleum hydrocarbons for conversion of heavy fractions into lighter fractions was originally done by thermal cracking which has been almost completely replaced by catalytic cracking because

The Meat of the Matter: A Look at the Meat Inspection Act of 1906 The year 1906 brought about a new era in governmental legislation that helped to shape the way privately owned producers of consumable goods would conduct themselves in the future. President Theodore Roosevelt‚ a man known for his tenaciousness when tackling the issues of the people‚ pursued these legislative changes‚ refusing to back down to the lobbyists who stood in his way. One such industry brought to its knees was the meat

Drunk driving “Please blow into this machine. Thank you.” If you are a driver‚ this sentence is familiar to you. Many police examine drunk driving at the crossroads every day. Meanwhile‚ numbers of advertisements and messages on TVs and radios persuade us not to drive after drinking. Driving without drinking has become a common understanding. But why do we have to accept this? And what would we do if somebody is drunk driving? Today‚ I hope to convince you that drunk driving is terrible and that
