Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

digestion process (McD‚ 2002). Enzymes are biological catalyst that help speed up the reaction by lowering the activation energy. These enzymes allow your food to be digested at a faster rate (National Institute of Asian Medicine‚ 2007). There are many factors that can affect the efficiency of enzymes which include pH levels‚ the amount of substrate‚ inhibitors‚ and temperature (Your Mom‚ 1996). Temperature is the independent variable that will be looked at to see how it will affect the activity of enzymes

and therefore can change it’s shape to better accommodate its substrate; this is the induced fit model (D. Fraser‚ 50). When an enzyme binds to a substrate‚ it is called the enzyme substrate complex‚ where the substrate is then converted into different products. As an enzyme is not a part the reaction‚ it remains unchanged and therefore can continue binding to other substrate molecules‚ catalysing the same reaction repeatedly (D. Fraser‚ 51).

Abstract This paper is about the Capitonyms and the affective of capitonyms on the learning and writing‚ it contains some sections. The first section is the introduction of the paper which contains the aims‚ problems‚ and the significant. The second section is the definitions of Capitonyms and showing the differences of capitonyms with homograph‚ capitalizing‚ and heteronym‚ and gives an explanation of using the capitonyms in writing. The third section is a list of some

Universal Declaration of Human Rights. Education is a life long process that began from the moment our parents thought us how to utter words‚ to read‚ count and write from the time we first took our first step to our school- to the society and ends just after we enter our grave. Education for most of us is the tool that can broke the inherited like cycle of poverty and a key to achieve one’s happiness and dream. To achieve a good education that can be applied in the harsh realities of life‚ one’s need to

Abstract: Light from the Sun is a full spectrum of different wavelengths of light. Scientists refer to this light as “white light”. When the wavelength of visible light changes‚ so does the color seen by the eye. The shortest wavelengths visible to the human eye are violet (400 nanometers). The longest wavelengths visible the human eye are red (700 nanometers). Each plant is affected differently by the changing wavelengths of light. The purpose of this experiment is to test the effects of different wavelengths

Question: How can different masses of salt affect the percentage of transmitted light? Variables – Independent – • Mass of salt‚ the salt added into the distilled water in grams (0.1‚ 0.5‚ 0.75‚ 1‚ 1.5) Dependent – • Percentage of transmitted light through the solution using 5 different mass of salt and a constant availability of 2g of sugar as source of food. (there are 5 trails for each conical flask representing 5 different salt masses) Controlled – What is being Controlled? How will

There are many different types of transitions during life between the ages of 0 -19. Some are common‚ happening to most‚ if not all children. Others are less common‚ happening to fewer (a minority) children. All changes can affect children and young people in some way. If children are able to be given the opportunity to ask questions‚ and discuss changes and events then this could help lessen any anxieties and negative effects on their development. Four main types of transitions are below.
