LABORATORY REPORT Activity: Enzyme Activity Name: Natalie Banc Instructor: Elizabeth Kraske Date: 09.26.2016 Predictions 1. Sucrase will have the greatest activity at pH 6 2. Sucrase will have the greatest activity at 50 °C (122 °F) 3.
It was hypothesized that the optimal pH for the enzyme was pH 7 while the 1.0 ml peroxidase would have the best reaction rate. At the end of the experiment the results prove the hypothesis to be incorrect. INTRODUCTION Enzymes are proteins that allow a reaction to speed up. These proteins are made up of monomers known as amino acids.

Enzymes speed up chemical reactions enabling more products to be formed within a shorter span of time. Enzymes are fragile and easily disrupted by heat or other mild treatment. Studying the effect of temperature and substrate concentration on enzyme concentration allows better understanding of optimum conditions which enzymes can function. An example of an enzyme catalyzed reaction is enzymatic hydrolysis of an artificial substrate, o-Nitrophenylgalactoside (ONPG) used in place of lactose. Upon hydrolysis by B-galactosidase, a yellow colored compound o-Nitrophenol (ONP) is formed.
Introduction: Enzymes are needed for survival in any living system and they control cellular reactions. Enzymes speed up chemical reactions by lowering the energy needed for molecules to begin reacting with each other. They do this by forming an enzyme-substrate complex that reduces energy that is required for a specific reaction to occur. Enzymes determine their functions by their shape and structure. Enzymes are made of amino acids, it 's made of anywhere from a hundred to a million amino acids, each they are bonded to other chemical bonds.
Enzymes are proteins that significantly speed up the rate of chemical reactions that take place within cells. Some enzymes help to break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates.
In order for organisms to carry on life, energy must be provided. The food taken into the body must be broken down into smaller pieces before it can be used as a source of energy by the organism. This process of breaking down food is called digestion and there are many enzymes used in order for digestion to occur. Enzymes are catalysts, which means that they can start and speed up a chemical reaction. Without enzymes in our body, it would take a longer period of time for digestion to occur.
Introduction: Enzymes are biological catalysts that increase the rate of a reaction without being chemically changed. Enzymes are globular proteins that contain an active site. A specific substrate binds to the active site of the enzyme chemically and structurally (4). Enzymes also increase the rate of a reaction by decreasing the activation energy for that reaction which is the minimum energy required for the reaction to take place (3). Multiple factors affect the activity of an enzyme (1).
An enzyme is a biomolecule that acts as a catalyst in biochemical reactions (1). Enzymes are commonly used in many products and medications. Enzymes function by flexibly binding to active sites in substrates (reactants). This binding is weak non-covalent interactions.
Rationale: Enzymes are used to make reactions faster. When there is more substrate the enzyme will be forced to work harder to get rid of it faster. The problem is that eventually the enzyme hits a threshold where it becomes so saturated with substrate that it can’t go any faster,
They can only quicken reactions that will eventually occur, but this enables the cell to have a productive metabolism, routing chemicals through metabolic pathways. Enzymes are very specific for the reactions they catalyze; they make sure the chemical processes go in the cell at any given time. Peroxidase was the enzyme being testing in this experiment. A peroxidase is an enzyme that acts as catalysts, which occurs in biological systems. Peroxidase is found in plants, which they play a role in helping to minimize damage caused by stress factors or insect pests.
Usually, the microbial enzymes have various potential uses in industries and medicine. The microbial enzymes are also more reliable than plant and animal enzymes as they are more stable and active. Also the microorganisms demonstrate an alternative source of enzymes because they can be cultured in large quantities in a short time by fermentation and owing to their biochemical diversity and susceptibility to gene manipulation. Industries are looking for new microbial strains in order to produce different enzymes to fulfil the current enzyme
This happens because enzymes lower the activation energy, as they provide an alternative reaction pathway. The decrease in the energy level aids in making the process happen faster (Jae In Lee, 2011) A catalase is an enzyme, which is found in all living organisms. This enzyme helps to convert hydrogen peroxide into oxygen and water. Chemical actions that happen within the cell produces hydrogen peroxide, which is poisonous and therefore can kill the organism.
It is an important step in restoring health and well-being by helping to remedy to digestive problems. Food (plant) enzymes and pancreatic (animal) enzymes complement to boost digestion and absorption of essential nutrients. Enzymes are protein molecules which are used (like catalysts) by different parts of the body to perform all of its chemical reactions converting substrate into product. Catalysts are simple inorganic molecules. The human body, typically, makes 22 digestive enzymes capable of digesting carbohydrates, sugars, proteins, and fats.
Enzymes are a huge factor in the human bodies physiology, without out them we wouldn’t be able to digest any of our food. If we didn’t have enzymes in our body to speed up the breakdown of the food we consume, our food would never break down fast enough in order for our bodies to get the proper nutrients it needs to survive. In an experiment the rate of an enzymes was measured by measuring the substrate reaction. The results showed that the rate of enzymes increased as the temperature, and enzyme concentration increased as well (Tian and Tsou,
