Single displacement reaction

Introduction Homeostasis is the state of a stable internal cell environment. If the cell is not in a state of homeostasis, then the cell will not be able to live and function properly. The plasma membrane is selectively permeable and controls what molecules enter and exit the cell. The plasma membrane keeps the environment inside the cell relatively stable which is the state of homeostasis. The goal of this investigation is to see if the size of the cell is affected when the cells are put in…

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 the reaction. All of these methods are implemented by the enzyme binding to the substrate or substrates. Substrates bind…

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 of the reactants and products are equal. In a written reaction, equilibrium is represented by two arrows going in…

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 recorded the highest reaction rate at 1.57 seconds-1. The 5 v/v % hydrogen peroxide concentration recorded a lower reaction rate…

the action of enzymes to carry out the reactions of life. According to the text in Campbell Biology, enzymes are biological catalysts. These globular proteins speed the rate at which metabolic 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…

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…

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 baking soda, the temperature…

A group of biologists have developed a general model to explain growth and development in ectothermic organisms. Changes in environmental temperatures effect the rates of most biological reactions and biological processes in ectotherms. The rates of ontogenetic growth and development are no exceptions. Ectothermic animals develop faster at warmer temperatures and they usually mature at smaller body sizes. This phenomenon has been called the temperature size rule (Zuo et Al. 2011). The…

To start with, the moderately high reaction rate contrasted and other longitudinal studies includes a level of significant outside legitimacy to the particular populace examined. Second, the three sorts of part stressors were measured at the same time and were inspected at two separate times…

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…
