What was the Bauhaus and what was its purpose? The Bauhaus was a school of art‚ architecture and design that existed in three German cities including Weimar‚ Dessau‚ and Berlin. The school was founded by Walter Gropius in 1919 and it lasted until 1933. During its time‚ Bauhaus went through different distinct periods under different directors and cities including expressionism‚ constructivism‚ functionalism and architecture. The Bauhaus was the start of modernism‚ at the same time‚ it changed the

Investigating 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

We are studying the effect of pH on catalase activity. Catalase by scavenging hydrogen peroxide to water and oxygen is an important enzyme of cell defense mechanisms against oxidative stress in all living organisms (Dat et al.‚ 2003). Cells use catalase because it is the most efficient enzyme as an antioxidative enzyme which lowers hydrogen peroxide or superoxide to accumulate to toxic levels in plant growth (Bowler et al. 1992). The formula that involves catalase as the enzyme is . pH is a measure

Memory “boosted” using Transcranial Magnetic Stimulation (TMS) Researchers at Northwestern University claim to have successfully improved memory functions through the use of transcranial magnetic stimulation (TMS)‚ a noninvasive technique used to excite or inhibit neurons within the human brain. Prior to testing the participants’ memory abilities‚ each individual’s brain activity was recorded during an magnetic resonance imaging (MRI) scan in order for researchers to precisely target s

cannot protect teens all the time‚ especially from themselves. As a result‚ the legislature has proposed an increased driving age from sixteen to eighteen to try to alleviate these issues. I believe increasing the minimum driving age will help protect our citizens by better preparing drivers‚ increasing safety for motorists‚ and setting a higher level of maturity on the road. Although it may seem cruel to teens‚ raising the minimum driving age will allow drivers to become better prepared. In school

Date: 03/20/2013 Lab: # Purpose of this lab: To test for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function
