Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

In the Kingdom Exploration lab‚ five different organisms were observed under a microscope‚ (Yeast‚ Paramecium‚ Elodea‚ Daphnia‚ Euglena). Each of these organisms is apart of one of the six kingdoms‚ (Eubacteria‚ Archaebacteria‚ Fungi‚ Protista‚ Plantae‚ and Animalia) which are apart of three domains‚ (Archaea‚ Bacteria‚ and Eukarya). In this lab‚ however‚ none of the organisms observed were archaea or bacteria. Also‚ all the organisms were eukaryotes‚ not prokaryotes‚ which are organisms without

In experiment one‚ involving the rate of respiration of germinated peas when exposed to a variety of different temperatures. From a general standpoint the data collected matched the hypothesis formed‚ as the temperature increases the rate of respiration will increase as well. This was shown as the average ppm of oxygen was taken from each group. Comparing the data from the class is shows the effect of human error on the results. For example group #4 seemed to have back wards results this may

A few stages in glycolysis are controlled‚ yet the most vital control point is the third step of the pathway‚ which is catalysed by a compound called phosphofructokinase (PFK). This response is the main conferred step‚ making PFK a focal focus for control of the glycolysis pathway as a whole. PFK is directed by ATP‚ an ADP subordinate called AMP‚ and citrate‚ and in addition some other molecules. ATP is a negative controller of PFK‚ which bodes well: if there is as of now a lot of ATP in the phone

The purpose of the unknown bacteria lab assignment was to select an unknown bacteria culture and‚ through a series of metabolic tests‚ identify which bacteria genus resided in the pure culture received. A nutrient broth inoculated with bacterial culture (numbered 45‚ henceforth referenced as U45) was selected and a streak plate was made to isolate a pure culture for use throughout the assignment. From the streak plate‚ several slides were made to determine the morphology of unknown 45. A Gram stain

facultative aerobe prefers oxygen but it is not necessary for growth. Many of these microorganisms will grow at the top of the tube‚ but will also be dispersed throughout as well. B. Discuss the temperature requirements of the organisms (you grew) in this lab. Both Staphylococcus epidermis and Lactobacillus acidophilus are mesophiles. Mesophiles grow best between 25- 45 degrees Celsius (Alonzo‚ n.d.). In this experiment both bacteria have grown easily at a maintained room temperature of 26 Celsius. C

Link reaction The link reaction takes place in the mitochondrial matrix and its main function is to turn the pyruvate into acetate for the kerb cycle. During the link reaction the pyruvate molecule undergoes decarboxylation and dehydrogenation‚ the enzymes pyruvate decarboxylase and pyruvate dehydrogenase remove the carboxyl group (which becomes a carbon dioxide molecule) and removes the hydrogen atoms from the pyruvate molecule. The coenzyme NAD accepts the two hydrogen atoms and becomes reduced

- Cellular Respiration Assignment - 1. What two molecules are formed when a phosphate is removed from ATP? There are three phosphate groups in ATP molecule (Adenosine Triphosphate)‚ when removing one phosphate molecule‚ ADP molecule is formed (Adenosine Diphosphate). 2. What is the function of ATP? Describe the molecule. The function of ATP is storing energy within a cell. ATP is adenosine triphosphate‚ C10H16N5O13P3‚ a high energy complex‚ giving the necessary power to push metabolistic

ABSTRACT The effect of co-factor (MgSO₄) and the nature of substrate on the rate of cellular respiration in yeast were determined using two different set-ups. In the first set-up‚ two test tubes were used where one contains 7m and the other with 7 mL 0.2M MgSO₄ and both containing 7mL 10% yeast suspension. Here‚ data shows that the H₂O mixture showed higher amount of CO₂ evolved than MgSO₄. In the second set-up‚ six Smith fermentation tubes were used each containing different 15mL solution (starch

This lab was completed to determine the rate in which fermentation occurs in different sugars and to compare the rate of cellular respiration in germinating and non-germinating soybeans. Fermentation breaks down sugars for a source of energy. Cellular respiration is the process used by cells to produce energy from nutrients. This process allows sugars and foods to be broke down in order to obtain energy from adenosine triphosphate (ATP). Cellular respiration is vital for survival of cells. Oxygen
