Results Worksheet
These are to be written individually even if you worked in a group.
Lab Topic: ________________________________________________
Introduction:
What was your null hypothesis? be specific
A change in temperature in the reaction of catechol and catecholase will not change the absorbance of reaction over time.
What was your alternative hypothesis? be specific
As the environment and temperature is changed from 0 °c to 20°c to 95°c, the absorbance of catechol and catecholase reaction will increase over time. The rate of reaction increases as the temperature increases.
Results:
What were the main trends or patterns in your data (Results)? In the Icebath reaction at 0°c has a mean concentration (which is calculated by [(absorbance-0.014)/1.0905]) of 0.824mM at 0 seconds and a mean concentration of 0.263mM at 180 seconds. This pattern of concentration increasing as the time increases is seen in the other two temperatures as well. In the reaction at 20°c (room temperature) at 0 seconds the mean concentration is 0.118mM and at 180 seconds the mean concentration is 0.525mM. This reaction at room temperature had the highest final concentration value of all the reactions. Lastly, in the water bath reaction at 95°c the absorbance along with the concentration increases over time, just like in the other temperatures. The water bath reaction at 95°c has a mean concentration of 0.361mM at 0 seconds and a mean concentration of 0.400mM at 180 seconds.

What were the important results relative to your hypotheses (Conclusions)?
What was important about the results

    During this experiment, acids of different concentration are utilized, and the different reaction rates calculated. When the reactant’s concentration increases, there are more atoms per space for a collision to occur. A prediction for the effect of concentration on reaction rate would be that the higher the concentration of the reaction, the faster the reaction time. As the temperature of the reaction rate increases, the molecules will move faster, also resulting in more collisions and perhaps a faster reaction rate.…

    The substances that I found to be bases are window cleaner, hand soap, baking soda, baking powder, bleach, Lysol, and antacid. These substances were found to be bases because after testing them by dipping pH paper into a well filled with about three drops of the substance, the color of the paper turned to a color correlating with the color of an eight or higher on the pH scale.…

    If the temperature was increased, the rate of reaction slows. If the temperature of the HCl was raised by 10°C, the activity will increase by 50-100%. This did not happen with the results shown in the chart above. Even small temperature changes such as 1-2°C can change the effect of the enzymes by 10-20%.…

    ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP, NADH, and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not, enzymes are mediated in the cytoplasm. The electron transport chain, chemiosmosis, and aerobic respiration use NADH molecule (which it main purpose is to transport electrons form one molecule to another) for later purposes. The mitochondrial matrix receives pyruvate from the cytoplasm after it crosses over the mitochondrial membrane. When the pyruvate enters the Krebs cycle it goes through many stages of biochemical enzyme-catalyzed reactions. In more detail about the cycle its main purpose is to produce little amounts of ATP by removing carbon dioxide and hydrogen from pyruvate molecules. Within the inner membrane of the mitochondrion the electron transport chain and chemiosmosis synthesis ATP with hydrogen ions which are NADH and FADH2. The Krebs cycle and glycolysis produce less ATP because chemiosmosis synthesizes a great amount of ATP.…

    This investigation used spectroscopy to evaluate light absorption in different solutions. A spectrophotometer was used in the lab to determine these values. A spectrophotometer is an apparatus used to “measure the absorption of radiation in the visible and UV regions of the spectrum and allows precise at a particular wave length” (Jones et al., 2007). The amount of light absorbed by a substance is directly in relation to the concentration of the solute and also the wavelength moving through the solute (Jones et al., 2007). This is commonly referred to as Beer’s Law and can be expressed as A= εl [C]. Beer’s Law equation measures the absorbency of light, making it an effective measure as spectrophotometers give exact values for absorbency (Jones et al., 2007).…

    Based on the results, the bunchberry plant, with a scientific name of Cornus canadensis, was most frequently seen in station four, the ecotone, and second most in station five, the forest which is most likely in the lower forest since it has a similar environment to that of station four, and third most in station three, the bog. It was not as frequently seen in areas of higher elevation such as the old field. It should be noted that all three locations were very moist which is expected since they receive water from the marsh. Due to its more frequent presence in moist environments, it is predicted that the bunchberry is more adapted to such locations. It is also predicted that sandy soil supports its growth since it was mostly seen in stations four and five which have sandy soil. Within and on the soil, lots of wood could be seen on the ground from remains of trees that were around the bunchberries which lead to a possibility that as the wood remains are buried in the soil, the bunchberry plant is able to use it to build roots.…

    This experiment was used to explore the Theory of Evolution created by Charles Darwin. The use of natural selection was apparent in the artificial modification of an organism 's traits which aided in this investigation. Through this experiment the Wisconsin Fast Plant was used. It is a fast-growing organism developed to improve the resistance to disease in cruciferous plants. This plant aids scientist in the exploration of environmental effects on population due to the speed to which is matures and reproduces. Artificial selection was stimulated by the selection against plants with few hairs (trichomes). Trichomes create a wider variation meaning it is polygenic. The plants that had only a few trichomes were exterminated and the rest were pollinated to create an F2 generation. This was done in an attempt to increase the number of plants with many hairs in the next generation. It turned out to be a successful use of natural selection due to the decreased amount of bald plants from the F1 generation to the F2 generation. Concerning how the experiment is actually performed, five Wisconsin fast seeds are planted into a cup full of soil and six fertilizer seeds. The seeds are then covered with more dirt and connected to a cup full of water through a wick. The soon to be plant is then placed under light for 24 hours. After this the plants with the highest amount of trichome numbers are found and kept. When flowers are present, the selected plants are cross pollinated with a pollinating stick and from there the plants are monitored and recorded.…
