Enzyme Activity Lab Report

Hello, I’m Nicole Gieser and I’m going to present to you my PACE experiment. The leading complication I’ve been trying to resolve begins with, how temperature affects enzyme activity. Also, discovering what happens inside the enzymes is also the focus. When I first found this experiment I had no idea what I was doing. I definitely needed to research on some vocabulary. But, with many websites to define what I needed, I knew what my projects focus was really about. Moving on, my hypothesis was the next objective to accomplish. Which moves to what I predicted would happen in this experiment. If the temperatures of enzyme-catalyst’s surroundings are increased then the reaction rate will speed up, because enzyme-catalysis reacts by randomly colliding …show more content…

Going back, a substrate molecule is a molecule in which they are the reactants involved in a biochemical reaction catalyzed by an enzyme. The higher the temperature of the enzymes’ surroundings, the faster the collisions happen, making the reaction rate faster. Again, my hypothesis was if the temperature of an enzyme-catalyst’s surroundings are increased, then the reaction rate will increase, because enzyme-catalysis reacts by randomly colliding with substrate molecules, and the higher the temperature the faster the collisions, or reaction rate. As I had previously mentioned, my data supports my hypothesis. In my hypothesis I mention that when the temperature is increased the reaction rate will increase. Continuing, in the tests conducted, the higher the temperature the faster the reactions happened. Next, its time to move on to the societal benefits for this experiment. Investigating the effect of enzymes based on temperature could help us further understand body processes, because enzymes are a big part of body functions and reactions. Continuing my last statement, we could also improve our knowledge on how medicines affect the body and how we can make them more

Because of the fact that reactions are catalyzed by enzymes when they randomly collide with substrate molecules, increasing the temperature would increase the reaction rate. Increasing the temperature further increases the vibrational energy of the enzyme molecules, straining the bonds that keep them together. Furthermore, when the temperature is higher, more bonds will break because of these strains, causing the active site of the enzymes to change too. Similar to pH, a change in the shape of the active site leads to the substrate not being able to fit perfectly, leading to the enzyme not being able to catalyze the reaction. Overall, an increase in temperature will cause the rate of reaction to increase initially due to the increased kinetic energy.

The effect of pH on the speed of enzyme interaction with substrate chemicals Hypothesis: About pH: If the pH level is less than 5, then the speed of the enzyme reaction will be slower. About temperature: If the temperature stays the same, then the speed of the enzyme reaction will not be completely affected. Background information: The function of enzymes is to speed up the biochemical reaction by lowering the activation energy, they do this by colliding with the substrate.

The baseline produced the slope of 0.0011x and when doubled it produced the slope of the 2x concentration of 0.0022x. When the base line slope of 0.0011x is divided it just about matches the result of the ½ x concentration slope of 0.0005. This shows the whatever the concentration of the enzyme is, it will react as fast as it is concentrated. The second baseline produced the slope of 0.0026x and when compared to the boiled enzyme slope of 0.004x shows that the reaction rate actually increased. This deviates from what is expected, because at that high of a temp it would be expected to not react at all or very slightly.

7. Will the temperature effect the pH Scale? Hypothesis: The hypothesis of this experiment is that the rate of reaction will increases well as the hydrogen peroxide concentration. If the temperature, pH and enzyme concentration is kept constant then the rate of reaction will start to decrease as well as the hydrogen peroxide concentration. Aim: To investigate the effects of changing the concentration of the enzyme catalase that it has on the rate of breaking down the Hydrogen Peroxide solution.

Abstract This experiment showed that temperature, concentration and pH all affect the rate of enzyme reaction differently. Enzymes are very important in organisms and therefore understanding how and why they work the way they do in specific conditions is crucial. The results showed that an increase in temperature would also increase the reaction rate, until a temperature that was too high, where the enzymes began to denature and therefore the rate of reaction was slowed down. As concentration was increased, the reaction rate continued to increase.

In conclusion, enzymes do cause reactions to go faster as the temperature increases however, once it has passed the optimum point, the reaction rate starts decreasing. Even though different temperatures can be handled by enzymes, if it is too extreme, the rate of the reaction will definitely slow as it will harm the

If the temperature is far from the optimal temperature the enzyme reaction slows down or cannot work at all. If the conditions are outside the normal range, the Catalase loses the ability to catalyze the peroxide reaction. Once Catalase loses this ability, some of the chemical bonds of the enzyme capitulate and the enzyme’s three-dimensional structure begins to decompose, and the enzyme begins to denature. As the temperature rises, reacting molecules increase the kinetic energy. This increases the chances of a positive collision and the rate

Aim: Therefore the aim of this experiment is to investigate the effect of increasing temperature on the activity of the enzyme catalyst. Hypthesis: The froth volume increases as temperature goes up until an optimum point of around about 40C and after that point the enzyme is denatured and the graph starts to decline.

The experiment was to test the if the efficiency of the enzyme catalase was affected by the temperature of its surroundings, by putting hydrogen peroxide on chicken liver (which has the enzyme catalase) in different temperatures. The results of the experiment showed that in a cool environment (about 20℃), the reaction with catalase and hydrogen peroxide produced about 10 ml of water, a moderate amount of bubbles (compared to the other 2 samples), and released 3℃ of heat the first trial and 1℃ of heat the second trial. This could mean that the reaction is an exothermic reaction, because there is heat being released during the reaction. However, in the same experiment done in room temperature (about 24℃), there were much less bubbles, only 6 ml of water produced, and there was no change in the temperature. Lastly, the experiment done in a warm environment (30℃) showed much more change.

Methods To figure out the effect of temperature on amylase activity one will need a total of sixteen test tubes, eight would be for the bacteria amylase and the other eight would be for the fungal amylase. Once the test tubes have been gathered, on a piece of tape label each test tube with the following temperatures; 0°C, 25°C, 55°C, 85°C. There would be four test tubes for each temperature. Get two test tubes from each temperature labeled and label two of those test tubes with an “S” (starch) and the other two with an “A” (amylase). Once completed, separate the test tubes so you do not mix up the bacteria and the fungal amylase.

Lab Report On Catalase And Temperature

Catalase and Temperature Introduction Background: Enzymes are catalysts which help reactions inside of organisms such as cells. Many different types of enzymes are used to catalyze different types of reactions. Enzymes are able to catalyze reactions that normally wouldn’t be possible under the specific circumstances in the cell such as the pressure or temperature of the cell. The way an enzyme works is it binds with the active site of a substrate and creates an enzyme substrate complex. The enzyme then breaks apart the bonds in a substrate and then leaves unchanged after the reaction.
