structure of the enzyme is mainly dependent on the active site and variable groups. Extreme temperatures or extreme pHs can alter the structure of an enzyme. Enzymes function to lower the activation energy to break the bonds. They achieve this by putting stress and pressure on the bonds or creating a microenvironment for the substrate. Enzymes are regulated by inhibitors or activators and can be inhibited by the products of the reaction‚ called feedback inhibition. Enzymes are catalytic proteins;

were recovering from World War I and the depression. Due to the fact that no one initially could or wanted to control Hitler’s dictatorial power his extreme racism got out of control and he was able to slaughter millions of Jews. Though eventually Hitler brought destruction upon himself‚ if other countries would have stopped him in the early stages‚ World War II may have never happened. Though countries might have wanted to stop Hitler in Germany; they had their own county and people to worry about.

He picked up the mirror‚ and took it into his mansion of a house in a quiet‚ peaceful suburb. It was a Midwestern winter‚ and the days were short‚ bringing cold nights whistled with the sounds of speeding cars flying down the highway. Eric heard the piercing call from his mother. "Eric‚ we’re going to McDonald’s. What do you want us to bring you back?" Eric thought

The time has come for my decision. Do I kill my partner in crime or do I let something else probably worse happen? Lennie has been by my side for awhile now and he’s my friend‚ hence the reason I haven’t left. I know I act harsh and cruel to him sometimes‚ but it needs to get through to him. And I know at the end of the day‚ Lennie still will care for me‚ not just because he forgets things‚ but because I’m his friend and he just wants me happy. But do I let him either be killed harshly by a jealous

The Effects on Enzymes By Bailey Rose The Effects on Enzymes Bailey Rose 10/31/2011 Abstract In this lab exercise‚ the study of enzyme catalase‚ we viewed the breakdown of hydrogen peroxide into water and oxygen. The purpose was to isolate catalase from starch and measure the rate of activity under different conditions. Changes in temperature and pH along with Substrate Concentration and Enzyme Concentration were the conditions tested in the experiment. Our class performed

comes from the Greek word “helios”‚ meaning sun. Helium is odourless and colourless and remains as a gas at room temperature; this chemical element is abbreviated as He. Helium has two protons in its nucleus whereas the atomic number of helium is 2 and is listed in group VIII of the periodic table. As a noble gas helium is almost chemically inert‚ unreactive. After hydrogen‚ helium is the most abundant element in the universe. During an eclipse in 1868‚ French astronomer Pierre Janssen discovered

Do you think you have good information about food literacy? Do you know what is the food literacy mean? The first thing we explain the mean of food. Food is any material taken to provide or support any creature with energy. Food many contain Carbohydrate ‚fats‚ proteins‚ vitamin and minerals. Food is considered the main thing in our lives. It is also the main source of enjoyment. Most food is taken directly from plants.(1) Food affects our health. When we eat healthy food‚ we preserve our lives.

the Effect of Temperature on Enzyme Activity Almost all chemical reactions that occur in living organisms are catalyzed by enzymes. Many factors in a cell’s environment affect the action of an enzyme. In this investigation‚ you will design an experiment to determine the effect of temperature on an enzyme-catalyzed reaction. You will complete an entire lab write-up using the CHS LAB REPORT FORMAT. Fundamental Question How does temperature affect the rate of an enzyme-catalyzed reaction? Materials

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction
