    help catalyze numerous reactions in the body. They are an arrangement of proteins designed to serve very specific roles. Enzymes contain active sites that substrates bind to. The enzymes then help orient those substrates so they achieve ideal reaction conditions. As a result, substrates are broken down much faster than they would on their own (Lawless 2016). Due to the fact that so many different arrangements of proteins are possible, it’s no surprise that so many reactions in the body are all…

    What is a chemist? A chemist is a scientist that studies, physical and chemical properties of different forms of matter. There are two profound chemist whose findings were crucial to today's understanding of chemistry. There names were Marie Curie and Dimitri Mendeleev, both chemist made significant impacts on modern day science and society. Dmitri Mendeleev is responsible for the creation of the periodic table, while Marie Curie is responsible for discovering radioactivity, which advanced the…

    The Rate of Chemical Reaction and the Factors Affecting Reaction Rates The purpose of these labs is to investigate and determine how three factors- concentration, temperature, and a catalyst- affect the rate of a chemical reaction. In the first lab, “Rate of Chemical Reaction,” 1 x 8-well micro strips were used to combine a potassium iodate solution and a sodium meta-bisulfite solution under different conditions; each trial was timed from the point of the first visible reaction until the last…

    The 'Wingate Cycle Ergometer Test' is an anaerobic test that is performed on a cycle ergometer. Eg. Monark. (Vandewalle et al. 1987). The aim of our test is to measure Peak Power Output(PPO), Relative Peak Power Output(RPP), Fatigue Index(FI) and Anaerobic Capacity(AC) throughout the Wingate Anaerobic Test. For both our participants we will compare our findings and provide an explanation for the similarities/differences we encounter between the two. Peak Power Output is the highest power output…

    Result and discussion: Substrate specificity The substrate specificity for the PPO is represented in table. The Km values for catechol, L-DOPA, L-tyrosine, and p-Cresol are 4.12 × 10-3, 16.4 × 10-3, 6.12 × 10-3, and 5.01 × 10-3, respectively. Catechol was the best suited substrate, having the lowest Km value and highest Vmax value when compared to other 3 substrates (Table 1). Table 1: Substrate specificity of PPO enzyme Substrates Specific activity (units mg-1 protein) Km (µM) Vmax (abs min-1)…

    INVESTIGATE AN ASPECT OF REDOX SYSTEM/REACTION Research Question: Does a higher voltage lead to more mass on graphite? INTRODUCTION Hypothesis: Higher voltage leads to more mass amassed on graphite electrode. Electrolysis- the process in which electric current passes through a solution to effect a chemical change. In this case there is copper, copper sulphate and graphite. In a electrolysis there is an electrolyte which is the copper sulphate, the anode which is the graphite. This is the…

    Research Question: How do different concentrations of nitric acid (measured in molars) with copper powder (grams) affect the rate of reaction (measured in seconds) measured using a stopwatch? Hypothesis: The copper powder placed in the most concentrated amount of nitric acid, measured in molar, will take the least amount of time, measured in seconds, to react compared to the amounts of copper powder in other less concentrated amounts of nitric acid. This is as if the concentration of nitric acid…
