My hypothesis for the germinated pea experiment was that the level of aerobic respiration would increase as the temperature would increase. I also predicted that there would be an upper temperature limit. The experiment proved part of my hypothesis correct and part of it incorrect. I was correct in predicting that the rate would increase as the temperature increase, but I was incorrect in hypothesizing that there would be an upper limit. My hypothesis for the larvae experiment was that the level of aerobic respiration would increase as the temperature increased and there would be an upper temperature limit. My hypothesis was proved to be correct, for the rate of respiration continued to increase until the upper limit was hit and the rate started to decline. There were no unexpected results from our group, but I noticed that group six had some unexpected data in the class larvae table. The only explanation I can make out of it is that the group made a math error. I do not have any suggestions to make this experiment better. Other factors that can affect the rate of cellular respiration are amount of available nutrients, because this allows more energy to be produced from the cell with an increase in amount of nutrients. Another factor is the state of the cell, such as the difference between working and dormant cells or the difference between plant and animal cells. From our data, we noticed that the temperature had an effect on the germinated Pisum sativum seeds. As the temperature increased, the rate of cellular respiration was doubled. At 45 degrees, the rate still increased, but it just barely increased. In the Zophobus morio we noticed that the rate increased from 10 degrees to 20 degrees. It then began to decrease as we continued to raise the temperature of the water. We got a negative amount for the 45-degree test of the experiment. Respiration is related closely to enzyme activity because enzymes start the reactions that are

    Cellular Respiration Lab Report Wednesday 8:00 A.M. Lab March 2nd, 2005 I. Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease in atmospheric pressure or temperature changes. There is a direct relationship between oxygen consumption and Carbon Dioxide produced, therefore the more O2 consumed the more CO2 produced. To keep the amount of CO2 produced from canceling out any pressure gained or lost from the consumption of CO2 we are adding KOH(Potassium Hydroxide) to the respirometers. Since the CO2 will be selectively removed the change in the volume of gas in the respirometer should be directly related to the oxygen consumed. In this experiment the germinating peas, in both water baths, should consume much more oxygen than the non-germinating peas or the glass beads, because germination has began thus accelerating cellular reactions and the rate of respiration. The cold water bath should slow the respiration down in all three respirometers.…

The hypothesis stated that since the germinated peas were still alive, they would contain a higher rate of respiration needed to remain healthy compared to the dried peas and glass beads.…

    Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. Most of the time, the photosynthetic process uses water and releases the oxygen.…

    2. The general redox reaction is XH2 + NAD+ → X + NADH + H+ . The purpose of transferring electrons is to produce NADH, which will be used in the electron transport chain to ship hydrogen ions onto the other side of the cristae membrane, to make a concentration gradient that will eventually be used to produce ATP. These redox reactions occur in almost all steps of cellular respiration, including glycolysis, “chemical grooming”, and the Krebs cycle. Without NADH produced, the electron transport chain couldn't function, which would jeopardize aerobic…

    Cellular respiration is the process of converting chemical energy of organic molecules such as glucose into a form of energy usable by organisms. This energy is mainly produced in the mitochondrial matrix and takes form in the molecule adenosine triphosphate [also known as ATP], which is made up of an adenosine with a three phosphate tail group. The reason why ATP produces energy is due to the loss of the third phosphate group. The third phosphate, when released, releases the bond energy and supplies it to whichever cell needs the energy. This causes the ATP to form into adenosine diphosphate [ADP], a molecule that does not supply energy to any cells. However, ADP can be refilled with phosphates to once again become ATP. ATP is constantly produced in an organism through a…
