Enzyme Reaction Under Specific Environmental Conditions

Enzyme Function Formal Lab Report Michaela McGrady Bio 05 Enzymes are a very important to the biological process. Enzymes help break down food and are essential in helping convert that food to energy. Enzymes have a single function, which makes them unique and need specific conditions in order for the reaction to occur.

How do enzymes work? Enzymes are biological molecules that act as catalysts. Enzymes help complex reactions occur everywhere in life. It is important to know what enzymes are proteins. Proteins are large and complex molecules that are composed of long chains of amino acids. Proteins are also essential parts of human life. Enzymes help to break down substances like food, and enzymes can be found in many household cleaning products that “break down” dirt and grime. Another purpose of enzymes is to accelerate chemical reactions. The relevance of doing the Enzyme Activity II in Bio110 Lab was to better understand enzymes; what they are, what they do and how they work. A further direction scientists in Bio110 Lab could take with enzymes is doing an experiment that tests how other factors besides temperature influence enzyme activity. To further results in the Enzyme Activity II lab, the scientists could redo the lab over to compare the results to their first lab to see how accurately they completed the first

Introductory Biology 1 Biology 1003 Fall Term 2011 Lab Number: 3 Title: Cell Energetics: Enzyme Role in Biological Reactions Name: Brandon Moore Student Number: 100819124 Lab day and time: Wednesday pm Date: Wednesday November 23, 2011 Introduction Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology Department, 2011).

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts, which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats, carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes, most physiological processes would not take place. Hundreds of different types of enzymes are present in plant and animal cells and each is very specific in its function.

Biology Enzymes IA Design Introduction: Enzymes are globular proteins, they are responsible for most of the chemical activities of a living organism. They act as catalysts, substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms, one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the enzymes to work. Temperature of the environment must be correct for each enzyme because different enzymes will have different temperature ranges in which they can live. pH levels in the environment must also be correct because if the

Enzymes are proteins that act as catalysts and help reactions take place. In short, enzymes reduce the energy needed for a reaction to take place, permitting a reaction to take place more easily. Some enzymes are shape specific and reduce the energy for certain reactions. Enzymes have unique folds of the amino acid chain which result in specifically shaped active sites (Frankova Fry 2013). When substrates fit in the active site of an enzyme, then it is able to catalyze the reaction. Enzyme activity is affected by the concentrations of the enzymes and substrate present (Worthington 2010). As the incidence of enzyme increases, the rate of reaction increases. Additionally, as the incidence of substrate increases so does the rate of reaction.

Introduction Enzymes are biological catalysts that facilitate specific chemical reactions (Raven, et al., 2014). Enzymes do their job by

• Enzymes are important in cellular metabolism. • Enzymes are involved in processes such as the breakdown of carbohydrates and converts them into energy for the body to use.

Abstract: After reviewing the basics of enzymes and catalysis, we take a dive into the wonderful

Introduction The purpose of this lab report is to investigate the effect of substrate concentration on enzyme activity as tested with the enzyme catalase and the substrate hydrogen peroxide at several concentrations to produce oxygen. It was assumed that an increase in hydrogen peroxide concentration would decrease the amount of

1b. Enzymes are proteins that act as biological catalysts. A catalyst is something that speeds up a reaction without changing its form. Enzymes speed up reactions by lowering the activation energy of a reaction. The activation energy of a

Enzymes are biological catalysts that are responsible for bringing and carrying out chemical reactions in the human body. These “reactions” are sped up using enzymes, allowing humans to have a higher metabolism. Enzymes are made up of proteins and bind to substrates to speed up reactions by lowering the activation energy. Enzymes bind to substrates on the active site. That being said, there are many factors that have effect enzyme activity, such as temperature, pH, and concentration.

Enzymes in Pineapple Background: Enzymes are very efficient catalysts for biochemical reactions. They speed up reactions by providing an alternative reaction pathway of lower activation energy. Like all catalysts, enzymes take part in the reaction - that is how they provide an alternative reaction pathway. But they do not undergo permanent changes and so remain unchanged at the end of the reaction. They can only alter the rate of reaction, not the position of the equilibrium. Enzymes are usually highly selective, catalyzing specific reactions only. This specificity is due to the shapes of the enzyme molecules.

Enzymes are biological catalysts, which speed up the rate of reaction without being used up during the reaction, which take place in living organisms. They do this by lowering the activation energy. The activation energy is the energy needed to start the reaction.
