PART B YOU WILL NOW DESIGN AN EXPERIMENT TO STUDY THE EFFECT OF A FACTOR AFFECTING VITAMIN C IN FRUIT JUICES WHAT IS THE EFFECT OF TEMPERATURE ON VITAMIN C IN FRUIT JUICES? The purpose of this experiment is to determine if the difference in temperature will damage vitamin C in any type of fruit juices. Five different temperatures of fruit juices will be used(5‚ 22‚ 50‚ 70‚ 90) degree Celsius to see how temperature affects the loss of vitamin C in fruit juices. The amount of vitamin C in the fruit

20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Temperature Effects on Radish (Raphanus sativus) Root Development Abstract Several studies have been conducted to establish how temperature‚ seed germination‚ and root growth are related. Because temperature plays a main role in many growth processes‚ we decided to focus on how it affected root growth. Radish (Raphanus sativus) seeds were chosen due to their ability to produce a distinct bulbous tuber‚ and their relatively short growing time. Three test groups were placed under different temperature

The Effects of Human Activity on Climate Climate is a natural activity that can be defined as the weather conditions prevailing in an area in general over a long period of time (which can include temperature‚ air pressure‚ humidity‚ precipitation‚ sunshine‚ cloudiness‚ and winds) (“Climate”). The climate has been a part of our environment long before humans came to study it‚ and really took it into consideration. Now through the many negative environmental actions created by humans through beneficial

Effects of Temperature on Beetroot Cell Membranes Background Information: A cell membranes is a thin structure that surrounds the whole cell. It contains the cytoplasm of a cell. The cell membrane is made up of hydrophilic region and a hydrophobic region. The hydrophilic region likes water‚ it is on the outside of the cell‚ the hydrophobic region is the inside of the cell where its protected from H2O. The cell membrane’s outer surface lets larger molecules into the cell. The inner surface deals

Enzymes are globular proteins that are synthesized by the ribosomes in a cell. They act as catalysts during biological reactions; therefore‚ enzymes are able to speed up these reactions without undergoing a permanent change themselves. These proteins are able to do this by lowering the activation energy of a reaction. To add on‚ enzymes require specific conditions under which they can work best. Reactions occur at faster rates when the temperature is higher. However‚ the rate of an enzyme-catalyzed

The effect of Temperature on the Xylem of Tomato Plants Question: How does temperature affect the Xylem in Tomato Plants? Introduction: Throughout this experiment I will be testing the size of the Xylem in Roma tomato plants when exposed to different temperatures. I will be placing six Roma Tomatoes in six different area which will each be in different temperatures. After three weeks of constantly watering the tomato plants with blue dyed water I will cut the plant from the root and examine

between temperature and light absorbance. The higher the temperature of the water surrounding the beetroot‚ the more coloured the water around the beetroot was. This is shown in the graph by: at 0°C‚ the water surrounding the beetroot was fairly pink and had an averaged amount of 0.074 absorbency. At 80°C‚ the water surrounding the beetroot was very pink almost red‚ and had an average of 0.982 absorbency. Conclusion The hypothesis was that beetroot left to diffuse at a higher temperature will have
