Titrations Lab Chem 102 virtual lab report titrations: neutralize an acid lake contamination this lab report is for you to reflect on what you completed and When the enzyme is added, the reaction starts, and the enzyme is therefore not included in the master mix. This is not a case where it is crucial to use a master mix; however, the skill is essential for many applications, and it is very useful in enzyme kinetics assays in general. Example 10.2.1 10.2. 1: Turnover number of acetylcholinesterase. Acetylcholinesterase (AChE) may be one of the fastest enzymes. It hydrolyzes acetylcholine to choline and an acetate group. One of the earliest values of the turnover number was 3 ×107 3 × 10 7 (molecules of acetylcholine) per minute per molecule of enzyme.End Repair Enzymes. Two enzymes are typically used for repairing DNA with sticky ends (see Figure 1) Polymerase: Polymerase fills in the missing bases for the strand, in the 5' to 3' direction. The resulting double-stranded DNA will be the same length as the initial longest DNA strand. Exonuclease: Exonuclease removes the 3' overhangs. Enzymes typically boost reaction rates by 10 5 to 10 7 ten to the five to ten to the seven times. [1,2]. Figure 1: A reaction from a substrate to product is a transition from one energy state to another. A transition state exists between the substrate and product. This state has a higher energy level than both the substrate and product. Labster About Virtual Labs for Biology.
