Enzymatic Reactions Enzymes are proteins found in living things that speed up chemical reactions. They aid in nearly all metabolic processes‚ such as food digestion‚ molecule synthesis‚ and the storage/ release of energy. An enzyme speeds up the rate of the chemical reactions by lowering the reaction’s activation energy‚ which means that by definition‚ an enzyme functions as biological catalyst. The activation energy is the energy that is used to get a reaction started. The function of an

effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are made up of proteins which are produced within living

Enzyme Catalase Activity in Reaction with the Substrate Hydrogen Peroxide Abstract We performed these experiments to observe the effects of enzymes on the rate of reactions. We tested and compared the activity of the enzyme catalase on the substrate H2O2 in various states and percentages‚ and observed the absorption values of the enzyme-substrate relationship at different concentrations. Our results show that the more substrate available‚ the quicker the reaction will happen except in one test

Adriana Rempson Mrs. Steeger AP Biology-7 10 October 2012 Transpiration in Plants Abstract: Our group wanted to see how transpiration would happen in plants when they were in different environments. The different environments we used were humidity and room environments. We measured transpiration using the whole plant method. Our results showed that the plants in a humid environment had greater transpiration rates than the plants in the room environment. Introduction: Pants absorb and

Google Case Write Up Google has long been seen as a phenomenal company to invest in. Year after year the company continually performs well and gets returns for it investors. This also results in a very high stock price for the company which in recent years has become more volatile. The reason for this was because it periodically missed analyst’s forecasts when it came to items such as EPS. Some believe that because they have a no guidance policy that missing the analyst’s forecasts has the possibility

Enzyme Reaction Rates Under Different Conditions Introduction In this lab you will observe how the rate of a reaction is changed as certain factors are changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the

that as the substrate concentration increases‚ the rate of reaction will increase respectively‚ until the enzyme reaches its optimum point of saturation‚ after which any increase in the substrate concentration will no longer affect the rate of reaction. The independent variable in this investigation is the varying concentrations of the substrate (Hydrogen Peroxide: 1%‚ 3%‚ 5% and 6%)The dependent variable was the rate of enzyme catalase activity‚ which was measured by the volume of froth produced

Computer Enzyme Action: Testing Catalase Activity 6A H2O2 is toxic to most living organisms. Many organisms are capable of enzymatically destroying the H2O2 before it can do much damage. H2O2 can be converted to oxygen and water‚ as follows: 2 H2O2 → 2 H2O + O2 Although this reaction occurs spontaneously‚ enzymes increase the rate considerably. At least two different enzymes are known to catalyze this reaction: catalase‚ found in animals and protists‚ and peroxidase‚ found in plants. A great

Experiments investigating the effect of a particular factor on an enzyme-catalysed reaction are commonly used as assessed practicals in Biology. The reason for this is there are a number of factors that can be investigated‚ and therefore‚ a number of factors that can also be controlled. From our lecture‚ we are aware that the following can affect the rate of reaction: 1) Temperature: a. Independent variable: A range of temperatures should be investigated‚ with particular attention

OF CATALASE REACTION IN HYDROGEN PEROXIDE INTRODUCTION Enzymes function similarly to a lock a key mechanism where only one specific key will work (U and Fischer‚ 1994). An enzyme is a macromolecule that acts to increase the rate of either a substrate breaking down into two or more products‚ or where two substrates join up to form one product (Dundon‚ 2018). These enzymes perform this by lowering the activation energy required for the reaction to occur under normal conditions. For the enzymes to lower
