Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

Functional properties such as colour (L*‚ a* and b*)‚ water activity‚ loose bulk density‚ tapped bulk density‚ flowability and cohesiveness in terms of Carr’s Index (CI) and Hausner Ratio (HR) of agglomerated goat milk powder were determined as follows; The colour of agglomerated goat milk powder was determined by Hunterlab colourimeter (Model: Colour Flex EZ). The 3-dimensional scale L*‚ a* and b* was used. The L* is the lightness coefficient‚ ranging from 0 (black) to 100 (white)‚ a* represents

Sugar – All Sweetness and Light? Sugar in all its forms is officially a simple carbohydrate. This means the body will convert is into glucose which is then available as energy. Then it gets less simple. Depending on the type of sugar used our health will be impacted rather differently‚ sometimes bad‚ sometimes very bad depending on using either natural or refined types of sugar. Whereas the usual over use of any sugar is likely to add fat and body weight and also play havoc with blood sugar levels

In this experiment‚ the scientists will research and test which of the four substances is the most efficient at absorbing water in cucumbers. The independent variable is the different substances being used. The dependent variable in the experiment is the amount of water absorbed. There are many constants including the same brand of cucumber slices‚ the same amount of each substance applied‚ the same measuring tools being used‚ and the same observation time. The control of these scientists’ experiment

Fresh potatoes extract in phosphate buffer pH6 containing the enzyme: polyphenol-oxidase‚ was used as the variable being tested in this experiment. You may refer to the Enzymatic Reactions Biology 21 Lab Manual. Santa Monica College by Logan‚ R. 2003 to see how the potatoes extract in phosphate buffer was made. We began this experiment by measuring seven constant amounts of 1ml of 0.1% catechol using a 1 mL pipet into each seven cuvettes. The catechol is our substrate solution. Next‚ different amounts

Introduction For several decades now‚ cleanliness is the first thing that everyone needs in our houses‚ schools‚ offices‚ and other. When someone visits our house or in schools‚ the first thing that they will notice or they will feel is our floor. They will feel the slippery of it and they will see how it was shined perfectly. Some people want to make their floor polished but they do not know what other product that is cheaper to use than the expensive product. Because of this I decided to make

Case Study #3 1. Out of the three time points‚ Max was the most dehydrated immediately after exercise. 2. The two parameters that can be used to determine Max’s hydration status is color and and pH. It is not specific gravity (SG) because Max’s SG is 1.035 which is within normal range. It is also not protein because in the lab manual it says that a trace amount of albumin in Max’s urine is normal. 3. If ADH levels increase‚ water reabsorption by the DCT/collecting ducts increases and the resulting

So‚ how does being a vegetarian have effects on your capability to build muscle? Possibly much less than you’d think or have been lead to believe. First off‚ man was likely really meant to be a plant eater and not a carnivore. Physiologically talking‚ man has all the features of a plant eater and not one of the traits of a carnivore. We have got the teeth‚ jaws‚ digestive enzymes‚ stomach astringency‚ and small intestines length of plant eaters. The most annoying and revolting of those is the small
