temperatures at 4°C, 23°C, 32°C, and 48°C , pH 3, 5, 7, and 9, the boiled extract, and hydroxylamine had on the peroxidase enzyme extracted from Brassica rapa. Emma O’Donoghue Fundamentals of Biology I Lab Professor William Olsen October 8, 2015 Abstract The purpose of this lab was to determine the effects that a number of factors had on enzyme activity. The enzyme used during this lab was peroxidase, which was extracted from the organism Brassica rapa. The peroxidase was…

because an increased enzyme presence allows the substrate to rapidly change into a product providing all other factors such as substrate concentration, pH, ionic concentration, and temperature remain unchanged or fixed. ("What Is the Effect of Substrate Concentration on Enzyme Activity?", 2016) PART B. Hypothesis: Influence of Substrate Concentrate on Catalase Activity It was hypothesized that if different diluted concentrations of hydrogen peroxide would relate to the rate of the enzyme…

Background Research Enzymes are proteins that act as biological catalysts. A catalyst can be defined as a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. Enzymes are essential due to the fact that virtually every metabolic reaction which takes place within a living organism is catalyzed by an enzyme. This is because organisms catalyze the chemical reactions that would otherwise not be able to progress under typical physiological…

recombinant CYP3A4 and CYP3A5. A significant decrease in the luminescene activity in both recombinant CYP3A4 and CYP3A5 was observed in 10 µM and 100 µM of PTV (Fig 1). It seems that PTV is a candidate drug for metabolism against CYP3A4 and CYP3A5 enzymes. Metabolite profiling and Identification After incubating PTV with HLMs in the presence of a NADPH regenerating system, a metabolite (M2) of PTV was profiled, characterized, and identified by LC-MS/MS. A representative chromatograms are…

Amylase Laboratory Report Introduction: Enzymes are a catalytic protein in a quaternary structure, that helps with the acceleration of molecules called substrates to achieve its desired chemical reaction. In this lab we used a specific enzyme called amylase. According to the lab manual, amylase is an enzyme found in one’s saliva or the pancreas to accelerate metabolism and cause a spontaneous reaction that helps with digestion of a substrate called starch. In order for any polymer such as…

shown in Figure 1. The metabolically active coenzymes of riboflavin are riboflavin -5-phosphate or Flavin Mononucleotide (FMN) and flavin adenine dinucleotide (FAD) that participate in many vital oxidation reduction processes. Catalytic sites of some enzymes are covalently bound with riboflavin as prosthetic group. FAD is not strictly referred as a dinucleotide because the ribityl moiety is not attached to the isoalloxazine ring by glycosidic linkage.In FMN, the phosphoric acid is attached to…

and temperature on the caseinolytic activity of crude protease were done. Stability towards temperature and pH were also evaluated. The pH and temperature activity curves and other stability studies suggested the possible presence of one proteolytic enzyme in the latex of Vallaris solanacea. In the present study, separation and purification of the cysteine protease…

Alkaline phosphatase (AP) is a homodimeric enzyme complex that is commonly found in a wide range of organisms, from bacteria to all tissues of the human body. AP is a zinc metalloenzyme (1), in which metal ions play a key role in the regulation of catalytic activities and stabilization of enzyme-substrate complex. As proposed by Gettins and Coleman using NMR studies (10), each active site of AP comprises of three metal binding sites, which acknowledged as M1, M2, and M3. Two zinc ions bind to…

Abstract: Catalase is an iron porphyrin enzyme present in high concentrations in humans and animals liver tissues. It is a peroxisomal enzyme that is responsible for destruction of toxic H2O2 released during certain metabolic processes.The activity of catalase can be determined by measuring the decrease in H2O2 concentration which is the substrate. Introduction: An enzyme is a large protein that acts as a biological catalyst which changes the rate of a reaction. It provides an active site…

and an SDH (Succinate Dehydrogenase) Assay. The goal of this project was to work with enzymes to gain a better understanding of how enzymes function and how they are impacted with the introduction of a variety of factors. A significant part of the experiment was determining the protein concentration of the prepared mitochondrial fraction which will be further explained. The reason for that is by increasing enzyme concentration present in a sample, it can increase the enzyme's activity and that…
