Solubility equilibrium

Group Members Zoe Ching, Juliet Contreras, Ailly Lam, Aleksi Ska. Background information Enzymes are biological catalysts, which speed up the rate of chemical reactions. The pancreas produces a concentrated solution containing a mixture of enzymes – amylase, lipase and protease. In this experiment you will examine the effect of protease on casein, the protein found in milk. When the protease breaks down the casein, the opaque solution will become transparent. Theoretically, Enzyme activity…

Introduction Enzymes are catalysts that speed up chemical reactions without being used up in the process. Enzymes are able to do this by bringing two substrates together and having them bind to the enzyme itself. This allows the enzyme to lower the activation energy required to start the chemical reaction by forcing the substrates into an unstable transition state. In order to make sure the substrates fit, enzymes are able to mold their half-moon shape to fit around the substrates.…

A Beautiful Mind is a movie that follows a young man named John Nash throughout his life from the time he enrolls in Princeton University until he receives the Noble Prize. Nash is determined to come up with his own original idea for his thesis which he does after a harsh rejection from a woman at a bar and inspires an idea. This allows Nash to write his paper then later leads to him teaching at MIT. Slowly and slowly throughout the movie, you can see Nash’s paranoia and mental instability arise…

(A) Explain, using examples, the following concepts from game theory: (i) a strategy, (ii) a strategy profile, (iii) dominant strategy equilibrium, (iv) pure strategy Nash equilibrium, (v) mixed strategy Nash equilibrium, (vi) a reaction function. (i) A strategy: A strategy refers to a move or action a player can make in any given game, where the outcome will depend on the players actions and the actions of others. A strategy determines what move/action a player will make at any given stage…

Chemical reactions are vital to living cells. Many chemical reactions take long periods of time to transpire. Enzymes serve as catalysts to speed up biochemical reactions in other substances. Each enzyme interacts with only one specific substrate (molecule) in an organism or a family of related molecules. Enzymes are not changed or used up by the reactions they catalyze, but their effectiveness can be influenced by environmental factors such as the pH level of an environment. All enzymes have an…

3. Jesper Juul View-Causal Revolution Jesper is a game scholar in game studies. He is a renowned author of the books Half-Real, Casual Revolution and The Art of Failure (Jones, 2008). We will slightly discuss the book casual Revolution which explains the various evolution in the video games by focusing on both hardcore players and casual players. Hardcore players refer to individuals engage in a game for long hours to create experience while casual players refer to those who engage in a game for…

The purpose of this lab is to solve for the equilibrium constant of a reaction between iron (iii) ions and thiocyanate ions. The lab is divided into two parts: one section recording absorbance of reference solutions and the other part for the absorbance of test solutions. The reference solutions were created through the mixing of excess iron (iii) nitrate (Fe(NO3)3) with a known concentration of potassium thiocyanate (KSCN) in order to push the reaction to completion; the initial concentration…

In this lab, seven test tubes containing solutions 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…

Introduction: All organisms depend on 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…

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…
