of photorespiration, photosynthesis or cellular respiration. This is significant because an enzyme operating in nonoptimal pH could have negative effects on the cell, and could pose a health threat to the organism. Enzymes proteins that speed up chemical reactions by lowering the activation energy. They do this by acting as a template for substrate orientation, stressing the substrates and stabilizing the transition state, providing a favorable microenvironment, or participating directly in…

equilibrium had different stresses added to them to examine the balance in each example. The purpose of the experiment was to indentify the details of shifting in equilibrium reactions and determine how the adding of a stress can affect a reaction. A chemical reaction that is in equilibrium is reversible, where a reactants can create products and products can go back to products. Equilibrium is reached when the rate of a forward reaction is the same as the reverse reaction and the concentration…

Trend The constant, 0 v/v % hydrogen peroxide solution, did not react with the catalase, therefore it was recorded as 300+ seconds and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration…

processes occur by lowering the activation energy or the energy barrier required to transform reactants to products. Each enzyme is specific, each containing active sites destined for a substrate. Substrates are the reactants or starting materials of chemical reactions. The binding of substrate to active sites orients molecules in a way that promote biological reactions to proceed to form products. The rate of enzyme activity can be impacted by environmental conditions such as material…

The problem being tested is how do different chemicals, such as ammonium chloride, calcium chloride, and sodium chloride, affect the temperature of the water? The hypothesis being studied is, if three grams of calcium chloride is mixed with 50.0mL of water, then the temperature will decrease because there are more atoms in calcium chloride than in ammonium chloride and sodium chloride. The independent variables is the type of chemical and the dependent variable is the change in the temperature…

Endothermic or Exothermic? The energy changes lab was an interesting lab in which the class compared two chemical reactions, the solute baking soda and the solvent vinegar, and the solvent baking soda solution with the solute of calcium chloride to see whether the changes were endothermic or exothermic reactions. I concluded that vinegar and baking soda was the endothermic reaction and baking soda solution and calcium chloride was the exothermic reaction. I knew this because in the vinegar and…

this, they have more tolerant tissues and can afford to eat less. Endotherms exhibit highly specialized tissues adapted to a certain narrow range of temperature and chemical composition that is maintained through homeostasis. Conversely, ectotherms have less specialized tissues that can tolerate greater changes in temperature and chemical composition. Because of this tolerance, ectotherms frequently have much longer life spans when compared to equivalent sized endotherms because of the greater…

Chapter 11, “The Chemical Elements”, was of great interest to me. “Chemistry is the study is the study of the composition and structure of matter (anything that has mass) and the chemical reactions by which substances are changed into other substances (James T. Shipman 285).” In this summary paper, I will discuss some of the highlights of the chapter. The way I see it, God is the original/first chemist. He took His own creations (the elements in our Periodic Table) to make provisions for…

Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…

the available chemistry classes, when the opportunity to job shadow a water operator at the Emlenton Water Treatment Plant arose, I took advantage of it. Even with my knowledge in chemistry, I went into the experience knowing only that they use chemicals, such as chlorine, to treat the water from the river. I came out of the experience with a more selective career path and a much greater knowledge and appreciation for water treatment plant operators. On my first day shadowing, I met my mentor,…
