The disappearance of my dad changed everything. It all started with a phone call. The message‚ echoing in my ear like a gunshot‚ was clear: my dad will move to China without us. At the time my father did not tell me the exact reason for his departure‚ but I read recently in a magazine that he was escaping from a group of lobbying businessmen‚ or more specifically‚ a group of gangsters. He was gone for a year‚ and‚ my seemingly perfect life was completely destroyed. At least I thought that was the

the spontaneous kinetic movement by which molecules move from an area of a high concentration to an area of low concentration. Diffusion continues until it reaches equilibrium. Osmosis is similar to Diffusion but it’s the process in which water moves across a semi-permeable membrane and goes to the higher concentration of solute.1 2.2. Important factors to Osmosis and Diffusion include Temperature‚ Concentration and Surface area to volume ratio. Temperature can affect the rate in which a solute

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

The Effect of Increasing Temperatures on the Enzyme Catalase Enzymes are proteins that help speed up chemical reactions inside your body and without enzymes‚ chemicals reactions in cells would be incredibly slow to a point where no activity at all takes place (Brawo press Inc‚ 2017). Enzymes speed up the chemical reactions by lowering the activations energy and they do this by binding substrates together in the correct orientation to react (Ernest Z‚ 2014). They are vital for life and serve a

supply run back to England was desperately needed. After the colony’s governor‚ John White‚ returned‚ everyone had vanished. The mystery behind the the Roanoke colony disappearance can be summed up in two theories: they moved locations and they were attacked by Natives. Undoubtedly the mystery of the Roanoke colony disappearance is baffling‚ but that hasn’t stopped speculations to arise. The first colonists were given two simple rules in their governors absence; carve the word

FUNCTIONS OF ENZYMES Enzymes are extremely important to the human body and its ability to function. An enzyme itself is a protein made by the body’s cells to act as catalyst‚ speeding up chemical reactions in the cell. It does this by taking the reactants‚ or the elements or compounds that enter into the chemical reaction‚ in this situation referred to as substrates‚ and breaking apart their bonds so that new ones can form. The three types of enzymes are digestive enzymes‚ food enzymes‚ and metabolic

RUNNING HEAD: Understanding Enzymes Understanding Enzymes Amanda Chung Blanche Ely High School Abstract The researcher conducted this experiment in order to investigate how various factors effected enzymes. Those factors were the concentration of the enzyme‚ the temperature it had to work in‚ and the pH level of the solutions as well. All three were hypothesized to speed up the rate at which the enzyme acted. A series of several tests were carried out to find the answer to each problem

Enzymes are proteins or nucleic acids that catalyze reactions. They are able to speed up reactions by reducing the activation energy of a reaction. Each kind of enzyme has a specific shape that matches its substrate so it can bind to its active site. Enzymes convert their substrates into a product. Enzyme activity are affected by factors such as temperature‚ pH‚ and time. If an enzyme is exposed to extreme heat‚ it will become denatured‚ that is‚ to become deformed and lose its original shape which
