Title of Lab: Preparation and Assay of Phenolase and Peroxidase from Sweet and Irish Potato Hypothesis: Polyphenol Oxidase enzyme activity can be detected by change in colour of solution‚ Inhibitors prevent the reaction of the enzymes with substrates‚ the enzyme is relatively specific. Aim: To design and conduct an experiment to demonstrate enzyme activity of Polyphenol Oxidase and Peroxidase when mixed with catechol‚ caffeic acid‚ pyrogallad‚ tyrosine‚ guacol‚ and water‚ to test the effect of

Measuring the effect of the concentration of caffeine on heartbeats. Caffeine is a stimulant which increases cardiac arrhythmia (improper heart rate) by increasing stress hormone (e.g. adrenaline) secretions. It also increases blood pressure which contributes to the blockage of receptors such as adenosine A1 and A2 receptors. The caffeine blocking receptors also blocks vasodilatory function‚ in which blood vessels become less dilated. Hence wise‚ caffeine is also known as a mild stimulant of the

ID:0720052 Effect of an Increasing Substrate Concentration on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding

history (USHMC 1). Auschwitz was miserable from start to finish. About 1.1 million prisoners were killed‚ only 90% were Jews (USHMC 2). This is what went on in Auschwitz from when the prisoners entered to when the prisoners left. Auschwitz Concentration Camp was opened in 1940 (ABEC 15). This camp was located in Poland (USHMC 26). As you entered this camp a sign that stated “Work Will Set You Free” was up to deceive the prisoners (ABEC 18). The prisoners thought if they worked‚ they would be set

The Spectrophotometer Determination Of Protein Concentrations And The Effects Sodium Dodecyl Sulphate And Triton X-100 Have On Protein Concentration. INTRODUCTION Spectroscopy is used as a collective term for all the analytical techniques based on the interaction of light and matter. Spectrophotometry is one of the branches of spectroscopy where we measure the absorption of light by molecules that are in a gas or vapour state or dissolved molecules/ions (Tombs‚ et.al‚ 1959). Spectroscopy is the

SUMMARY‚ COMCLUSSION AND RECOMMENDATION The main objective of the study was to develop sweet potato cookies. Specifically‚ it sought to (a) evaluate the sensory qualities of sweet potato cookies in terms of appearance‚ odor texture and taste. (b) determine the most suitable treatment based on general acceptability. (c) determine if there is a significant difference on the proximate composition between control and the most acceptable treatment in terms of moisture‚ ash‚ crude fat‚ and protein
