Sucrose and glucose concentrations were calculated from the concentration of NADPH formed by the reaction of glucose-6-phosphate and NADP+. Spectrophotometric absorbance readings were taken at

10. This is comparable to literature results. In the lab conducted, all Trypsin reactions were run in an environment at pH 8. The maximum rate of reaction found in lab was . The two rates are close in value. 2. pH affects the enzyme-catalysed reaction rates because all enzymes have an optimal pH range in which they can function (Royal Society of Chemistry, 2004). If the pH of their environment transgresses too far from their optimal pH, the enzyme will begin to denature. pH can affect

by temperature and pH. Every enzyme has an optimal temperature that it thrives at. As the temperature goes towards the optimal temperature the rate of enzyme catalyzed reactions increase; when the temperature passes the optimal region the rate of catalysed reactions decrease.  pH affects the enzyme in the way that temperature does, that is to say each enzyme has a pH that they function the best at and when the pH changes their productivity decreases. (Freeman, et al, 2014,

Enzymes are biological catalysts, they have specific functions and structures that catalyze chemical reactions within the body. Without the catalysing of these reactions, they would happen inefficiently and too slowly to sustain life. (Science Museum, 2017) Each reaction needs small amounts of energy to get started, this is known as activation energy. To start a chemical reaction, an enzyme works by lowering the amount of activation energy needed. Enzymes are proteins and are specific for their

Aerobic and Anaerobic Cellular Respiration Respiration describes sequences of enzyme-catalysed biochemical reactions within cells to produce life sustaining energy (Turtle, 2015). Muscle activity relies on biochemical energy from Adenosine triphosphate (ATP), a high-energy molecule in cells which stores and supplies energy. To make ATP, a muscle cell (Myocyte) utilises Oxygen provided by Myoglobin (a muscle-fibre oxygen-binding protein) and breaks down glucose in aerobic cellular respiration.

The conflict in Darfur, Sudan is an example of a world order conflict driven by access to resources, namely water, but is also caused by increasing demographic pressure and political marginalisation. The conflict over access to water in Sudan was catalysed by a decline in rainfall in the area, leading to failed harvests and competition for access to this resource, with other factors such as political marginalization influencing the violence.

Enzymes are biological molecules, mostly proteins, that speed up the rate of the chemical reactions that take place in the cells (Joseph Castro, 2014). They are proteins that act as catalysts within living cells. However, catalysts is used to increase the rate at which chemical reactions occur without being altered. A chemical reaction is a process that converts one or more substances, called substrates, to another type of substance, which is the product. With the catalyst, the enzyme can perform

Water is an essential chemical for the sustenance of life on Earth. Without water, organic matter would not exist and humans would not be able to sustain bodily processes[1]. Perhaps the most important process involving water is photosynthesis in plants. In this process, water and carbon dioxide are converted into glucose and oxygen using the energy from sunlight. Photosynthesis can be represented by the overall equation: 6CO2 + 6H2O → C6H12O6 + 6O2 This overall reaction actually takes place in

their behaviour in many ways (Gates, Newell & Wray, 2001). My views to date have changed slightly, as I have developed the opinion that ‘behavioural difficulties’ are the net result of a situation or problem, the student’s behaviour simply being catalysed by the environment or situation. This behaviour is usually difficult or problematic (Gates, Newell & Wray, 2001) for the teacher, or others, which is often when that student is categorised as troublesome, or labelled with ‘behavioural

What the Ethiopian case represents, nevertheless, is the role of the fourth claim. At the point when making the case that one 's practices and/or character don 't represent a risk however are rather under danger, security remains the predominant casing of reference and securitisation the core procedure locked in. To put it plainly, one is fighting securitisation with securitisation. Even more dangerously, however, as the evidences from Ethiopia uncovers, the very markers used to portray one 's threatened
