Catalase

A 59-year old white female presented to the Emergency Room department complaining of severe back pain that began two days prior. The patient was tender to the touch along the middle of the thoracic spine with no warmth or redness. The patient’s spine did reveal mild scoliosis but no gross deformities. There was no significant radiating pain to the surrounding spinal musculature. Although the patient was ambulatory, any movement such as walking, twisting side to side, bending over, or…

works and tell the reactions of it. How It Works: This large demonstration uses hydrogen peroxide, sodium iodide and soap. First, we pour in the hydrogen peroxide, then the soap and finally the sodium iodide. The yeast contains an enzyme called Catalase that breaks down hydrogen peroxide (H2O2) into oxygen, gas, and water. The oxygen gas gets trapped by the soap, and you get a large foamy solution that squirts out of the top of the bottle! hydrogen peroxide (3%) dish soap dry yeast warm…

Cerium is a rare earth element of the lanthanide series (atomic no. = 57– 71) of the periodic table. Among the various rare earth metals, cerium granted a hugeattention towards scientific community due to its catalytic antioxidant property. Usually, antioxidants protect cells from oxidative damage, mediated by ‘reactive oxygen species’ (ROS), which include free radicals such as superoxide anion (O2•-), hydroxyl radical (•OH), singlet oxygen (1O2) and non-free radical species like hydrogen…

They can control biological processes. For instance, • carboxypeptidase is an hydrolytic enzyme important in digestion, contains a zinc ion coordinated to many amino acid residues of the protein. • Another enzyme, catalase, which is an well-organized catalyst for the decomposition of hydrogen peroxide. Because it contains iron-porphyrin complexes. In both cases, the coordinated metal ions are probably the sites of catalytic activity. • Other coordination compounds…

After my gram staining I was able to comfortably eliminate all of the gram negative results. This encouraged me in knowing that I was able to execute an experiment efficiently enough to eliminate some of my choices. I was also able to eliminate all of the streptococcus bacteria because my bacteria was in clusters and not in a chain arrangement. Gram staining also helped me in eliminating the bacilli because my interpretation of the observation was that my unknown bacteria was spherical in nature…

components to cause damage to cell membrane and mitochondria of the heart muscle fibers [1] These free radicals may then cause injury to the heart, an organ that has a relatively low level of antioxidant enzymes such as superoxide dismutase (SOD) and catalase. Others studies propose that the mechanism of DOX-induced heart apoptosis is dependent on the activation of tumor suppressor p53 [9] [10]. Melatonin (MEL), is the chief secretory product of the pineal gland of all mammals. During the day…

Purpose: To identify an unknown microorganism by performing a series of biochemical tests on a pure bacterial culture. Materials and Methods: Carbohydrate Utilization: Materials: - Phenol red lactose Broth - Phenol Red Sucrose Broth - Unknown organism # 40 - Inoculating tool Procedure: Phenol red lactose and Phenol Sucrose were cultures used to identify fermentation of carbohydrates for the unknown organism #40. Phenol red is a ph. indicator as the inverted Durham tube indicates gas production…

the disease have been found to have abnormal TDP proteins in dying neurons, but it is believed that this structure can be created by damaged cells that attempt to repair themselves. The oxygen uptake system consists of superoxide dismutase enzymes, catalase and glutathione peroxidase. In this collection, SOD is a key enzyme, because it is involved in the first phase of the removal of free radicals. Three ISO-enzymes have been identified, including SOD, cytosolic (Cu / Zn SOD), mitochondrial SOD…

There were many tests performed on my unknown, which led me to conclude that the unknown microorganism is Pseudomonas fluorescens. When determining the gram reaction of the unknown, a Gram stain was done. This process differentiates between a Gram-positive and Gram-negative microorganism. This is done in four steps. The microorganism was stained with iodine, crystal violet, alcohol and acetone, and safranin. Iodine was used first as it acts as a mordant. It forms an insoluble complex by binding…
