Catalase Enzyme Lab Samiya Hussein March 9‚ 2012 Introduction In order to receive the necessary amounts of energy required for daily function‚ the digestive system must break down proteins‚ fats and carbohydrates. In doing so‚ the body produces poisonous chemicals; however‚ the cells aren’t harmed. This is because enzymes are used to break down these chemicals. The name of the enzyme that was the main focus of the lab is catalase. Catalase is responsible for catalyzing hydrogen peroxide

The main objective of this lab is to see if the rate of cellular respiration will be affected if we change the food source from glucose to three different experimental variables (fructose‚ sucrose‚ lactose). Cellular Respiration is a process that generates ATP and it involves the complete breakdown of glucose to carbon dioxide and water. Carbohydrates‚ fats‚ and proteins can all be used as fuels in cellular respiration‚ but glucose is most commonly used as an example to examine the reactions and

a prokaryote‚ a single celled organism lacking a cell membrane bound nucleus‚ and can be divided into bacteria and archaea. Proteus mirabilis is characterized by their motility‚ its ability to distinguish maltose‚ and its inability to distinguish lactose. Proteus has the ability to stretch itself out and secrete a polysaccharide when in contact with solid surfaces‚ in result making it extremely motile on items like medical equipment such as an indwelling urinary catheter. Proteus is part of the normal

concentration of the substrate (when [S] [E]). Specifically‚ we studied the kinetics of the enzyme lactase which is an enzyme that catalyzes the hydrolysis of lactose sugar into glucose and galactose as shown in the following reaction: C12H22O11 + H2O C6H12O12 + C6H12O12 Lactose is the disaccharide found in milk‚ and it requires lactase enzyme for proper digestion. To study lactase kinetics: first‚ we constructed a standard curve for Ortho-

alternatives such as soy‚ almond and coconut. One reason that cow’s milk is not as beneficial as a fortified alternative is that milk contains lactose making it more acidic. Approximately seventy-five percent of the world ’s population is lactose intolerant‚ which means that they are unable to fully digest dairy products. Lactase is the enzyme needed to digest lactose‚ and most people stop producing it around the age of 5. (Calcium and Milk) Another reason cow’s milk is not beneficial is its nutritional
