The Effect and Rate of the Enzyme Amylase on Starch Abstract Assessing reaction speed of the enzyme amylase can be measured by the amount of glucose and maltose produced during given time intervals. I hypothesized that‚ if the reaction time is longer‚ then the amount of amylase will be larger. Enzymes are specific in their match of substrates they will breakdown – similar to a key and its lock. Since amylase is the only enzyme that breaks down starch‚ the procedure was effective and gave clear

The Benefits of Extracurricular Activities There are many high schools out there today that provide a plethora of extracurricular activities. Some occur before school‚ some after school‚ and a few may even take place on the weekends. While some parents are a bit dubious about their children participating in extracurricular activities‚ these activities actually bring with them many benefits. Allowing your child to get involved in extracurricular activities at school is a wise choice‚ and it can

Strength of Activity Based Costing The major strength of activity based costing is the ability to estimate the cost of individual products and services precisely. By transferring overhead costs to individual units of products or services‚ ABC helps identify inefficient or non-profitable products or activities that help into the profitability of efficient processes or highly profitable products. 1. More accurate costing of products/services Product cost determination under activity-based costing

What pH Level Causes a Plant to Grow Best Alexis Chavez‚ Heather Nutt‚ Nguyen Phan Introduction We knew that water is normally stated as the best form of liquid to make sure plants grow as best as they can‚ but we wanted to know if causing the water to be more basic or more acidic would affect how the plant grew. Our hypothesis was that if the plant is treated with a pH of 12 then treated with another pH. Materials The materials used were three identical plants‚ that each had 4 sections that were

HINTS ON WRITING YOUR REPORT Title: Enzyme activity Objective: To investigate the effect of temperature on amylase activity Design principle Background: Amylase activity products? (show the equation) Which factors will affect enzyme activity? How to study the rate of reaction? (e.g. rate of disappearance of substrates or rate of formation of products) Independent variable: temperature of reaction mixture or at which the enzymatic reaction occurs. It can be varied by setting water bath at

can predict that the tube with the highest concentration of yeast will produce the most carbon dioxide and will have the fastest rate of alcoholic fermentation. Results Two separate experiments were conducted to determine the effect of yeast concentration and pH level on the rate of fermentation. The first experiment involved the placement of different concentrations of yeast‚ glucose‚ and distilled water in four different tubes. Pipette pumps were placed on each tube to allow the solution

Students are meant to be receiving an education and gaining recognised qualifications. Higher Education institutions place a greater importance on the curriculum than the co-curriculum when selecting students‚ and so do employers. Co-curricular activities are nice‚ but they have never been shown to actually play a vital role in a student’s life. And if they distract students from focusing on their academic qualifications‚ then they could be actually harmful. There is no obvious logic in having super
