MISEP Chemistry 512 – Jacobs Enzyme Catalyst Lab - Formal Report – August 8‚ 2007 ABSTRACT This investigation examined what would happen to the rate of an enzyme-catalyzed reaction if the concentration of substrate changed. We hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased

Design your own experiment: Effect of pH on enzymatic activity Background Information: Trypsin is a protease which conducts hydrolysis forming peptides. It is an enzyme which is secreted by the pancreas into the small intestine and works best in an alkaline environment. Egg white is used in this practical as it is found to contain the protein/ enzyme trypsin. pH is the measure of the amount of H+ ions in a solution‚ these ions affect the shape of the enzyme. Hypothesis: That as pH increases

construction material and magnetic materials fields. Temperature of ball mill has an important impact on the quality of products. To understand the issue of temperature control of ball mill can better finish grinding. Temperature of ball mill is big issue. Appropriate temperature must be set in production. Temperature not only affects the properties of ball mill material but also the grinding performance of grinding materials. The normal temperature of ball mill is high and there are many reasons

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

Harmful Effects of Soy Milk Soy milk naturally contains its numerous health benefits as nutritious alternatives that people seem to consume dairy. Since it is renowned an excellent source of high in protein and low in calories. To vegans or somebody who has the desire to lose weight‚ here is the worthy supplement. Especially in Asia where soy milk originated‚ a cup of warm soy milk in the morning or before bed is very popular. Nevertheless‚ though studies there are some compounds in soy which is

The Effects of pH‚ Temperature‚ Enzyme‚ and Substrate Concentrations on Benzoquinone Production BIOL 2051 June 10th 2013 Introduction Enzymes are the ultimate catalysts of living things. Enzymes are made of proteins which are structured and directed by amino acids chains. Enzymes attract and fit substrate molecules to an active site. The active site binds the substrate molecules covalently to enzyme forming an enzyme-substrate complex‚ which catalyzes

Classification of milk products based on the manufacturing process Milk is important for both children and adults because it is a source of minerals‚ calcium‚ protein and phosphorus. Currently‚ there are different kinds of milk products in the market. Here are some types of milk based on the manufacturing process: -UHT Liquid Milk UHT is stands for Ultra High Temperature Processing or Ultra Heat Treatment. It is a way to sterilize food through to high heat process about 24 seconds at 135-140

John A Professor Mallilo Milk‚ Healthy or Not? Most people drink milk everyday because it has been proven to increase bone strength and also helps slow down bone loss as we age. However‚ this seemingly harmless drink may be more harmful than it is healthy. Milk and other dairy products are packed with a lot of different nutrients that are essential for human survival and growth. As well as calcium‚ milk also has protein‚ potassium‚ phosphorus‚ vitamin D‚ vitamin B12‚ vitamin A‚ Riboflavin

curve on my graph. However‚ I believe due to human error the results were incorrect between temperatures of 60Ëšc and 80Ëšc causing this area of my graph not to follow the pattern of my initial prediction. I have also noticed that the highest rate is at a slightly higher temperature than I expected‚ though this may be due to the large difference in temperature between each sample. As the temperature was increases the molecules were given more energy and move around in the solution quicker

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable
