Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Abstract: In the village of Gopher Hollow there’s a cluster of Blue Baby Syndrome. There were four infants affected by this cluster. The families from the infants would collect their water from wells. We have to determine what’s the source of the high levels of nitrites in the water. The four sources that could be the point of contamination are a new subdivision‚ textile plant‚ an organic farm‚ and a mountain lake

Enzymes are biological catalysts and each individual enzyme can only catalyse to one type of reaction – due to its specific shape. Each individual enzyme has its own specific shape which is determined by the amino acid sequence that it is made up of – each enzyme’s active site matches to its unique substrate molecule. For the sake of our experiment – enzymes catalyse reactions because they become an active site for reactions to take place. This lowers the energy that is needed for the reaction but

Determination of the activation energy of an enzyme catalysed reaction Introduction In this practical the aim for this experiment was to find out the catalytic power of alkaline phosphate‚ as well as the rate of reaction and the activation energy of p-nitrophenol phosphate. Enzymes are biological molecules that catalyse a chemical reaction. ‘Enzymes work by lowering the activation energy of a chemical reaction making it easier to proceed’ [1]. This allows molecules to have more energy therefore

Catecholase-Catalyzed Reaction Abstract This paper describes an experiment to determine ……………. Introduction Enzymes are made from proteins. They are biological catalysts that speed up the rate of chemical reaction by lowering the activation energy of the reaction. Enzymes are precise and catalyze only detailed reaction. Specificity is an outcome of active site of enzyme that acts on the substrate. Catecholase‚ which catalyzes a reaction in which catechol‚ then catechol becomes the product

by pH is the purpose of this experiment. Introduction Enzymes play an important role in daily life because of the chemical reactions. Almost chemical reactions require the presence of enzymes to promote the metabolic process. They are known as the incredibly efficient and highly specific biological catalysts. Most enzymes are protein with the ability to enhance the rate of reaction between molecules. To catalyze a reaction‚ the enzymes have to create the best environment that is called active
Premium Enzyme Metabolism Catalysis
Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. Enzymes are catalyst for biochemical reactions; Enzymes lower the activation ATP so a reaction can begin over the energy barriers. In this lab‚ a discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches

bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that energy is released in the form of heat. It is the fastest known enzyme. Hydrogen peroxide Water + Oxygen 2H2O2 2H2O O2 List of materials: Safety glasses Iron powder in a watch

Agar is also used in medicines to promote peristalsis and relieve constipation and is resistant to a breakdown by bacterial enzymes. Sodium carbonate‚ Na2CO3‚ also known as washing soda or soda ash‚ is a sodium salt of carbonic acid. It can be extracted from the ashes of many plants and has a cooling alkaline taste. It is one of the most basic industrial chemicals. The acid’s

All living organism depend on catalytic proteins called enzymes‚ these compound are responsible for metabolism and biochemical regulation of energy‚ there are millions of enzymes and hundreds of enzymes have been identified in the human body as well. All living system possess enzymes as vital components of the body‚ enzymes are found in all organisms. Everyone has a natural pH balance in the body. Enzymes are complex proteins which speed up chemical reactions if this did not happen it would occur

Lab 1: Homeostasis Background Information: Homeostasis is the existence of a stable environment in the body for survival. This process is always regulating bodily functions in order to keep the body in optimal condition. When conditions change a receptor senses and sends a message to a control center. The control center processes the information and sends an appropriate command to effectors. These effectors will respond to the command which will stimulate a positive or negative response. A positive
