The effect temperature has on the activity of the enzyme α- amylase. Introduction Enzymes are a biological catalysts‚ which means that they speed up the chemical reactions in living organisms. Almost all of enzymes are energized protein molecules that catalyse and regulate nearly all biochemical reactions that occur within the human body. The reason in which enzymes are sensitive to heat‚ pH and heavy metal ions is because they are made up of proteins. The food we eat is turned into energy by enzymes

is not active then no agglutination will occur. To test the hemagglutination reaction‚ two types of ConA solutions were compared‚ a purchased control ConA solution in buffer as the positive control‚ and a purified solution of ConA in buffer previously purified in lab. Each solution was at a 2mg/ml concentration of ConA in ConA buffer‚ which is necessary for ConA’s biological activity. Two variables were added‚ Galactose and Mannose‚ to the ConA solution to compare the effects each had on the hemagglutination

negative net charge will move toward the positive electrode. An inert substance such as paper or gel is used as a supporting medium for the conducting liquid in most electrophoretic methods. In this experiment of separating amino acids‚ a phosphate buffer (pH 6) will be used as the conducting liquid and cellulose as the supporting medium. Purpose: The purpose of this experiment is to determine the effect of an electrical field on charged particles and to use this information to identify the amino

Discuss the function of a buffer. How will pH change when small amounts of acids or bases are added to the buffer solution? Answer: A buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. Its pH changes very little when a small amount of strong

Carl G. Butil‚ Conrad G. Leonida‚ Renee Theresa ABSTRACT This activity observes the DNA present in onion (Allium cepa) and human cheek cells by extracting it with the addition of lysis buffer and chilled ethanol. The lysis buffer is prepared from squeezed onion mixed with salt and Pantene Pro-V Shampoo. The buffer degrades the protein enveloping the DNA found in onion and cheek cells Cheek cells are obtained from gargled gatorade. Extracts are then filtered and subjected to addition of chilled ethanol
