Enzyme Lab Introduction/ Abstract An enzyme is a substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. They are mainly made up of proteins and can tremendously speed up reactions. E. coli ( a bacterium) has about 1‚000 different types of enzymes floating around in its cytoplasm at any given time. Enzymes can be used to join and even break up molecules as shown in the diagram below. (1)

Biomes Comparison Essay Ecologists group earth’s diverse environments into biomes. A biome is a complex of terrestrial communities that develops a large area and is characterized by certain soil climate conditions and particular assemblages of plants and animals. Not all species live in every biome they vary in their adaptations to different conditions. An adaptation is an inherited characteristic that increases an organism’s ability to survive and reproduce. These sorts of variations in plants

The Discovery of Biological Taxonomy Taxonomy is the scientific classification of living organisms. It is known that two main naturalists were responsible for discovering and founding this classification method‚ John Ray and Carl Linnaeus. Biological Taxonomy has a hierarchy of seven main ranks; Kingdom‚ Phylum (Division if it is Botany)‚ Class‚ Order‚ Family‚ Genus and Species. These classify every living thing from Animals to Bacteria. Some of the classification system is written English

The Discovery of The Rosetta Stone One of the most important by-products of the French invasion of Egypt was the knowledge gathered by the scientists and historians who journeyed along with the army. But‚ of all the discoveries made‚ the most important was the Rosetta Stone‚ the key that unlocked the ancient marvels of Egypt. Do any of you know what the Rosetta Stone is? The Rosetta stone is a very important artifact that was discovered during the French invasion of Egypt in the year 1799. You

Enzyme Assignment Research SBI4U Test A2 Table of Contents 1. What are the function roles and biological significance of the enzyme? Trypsin is part of the digestive system and degrades proteins‚ making it an enzyme known as protease. [1] It is one of the three principal digestive proteinases‚ the other two being pepsin and chymotrypsin. [9] Trypsin primarily hydrolyses peptides into smaller building-blocks‚ mainly amino acids (these peptides are the result of

A Journey for Self Discovery NAME DeVry University‚ English 092 Date A A Journey for Self Discovery Learning what elements motivate me helped me to identify my purpose. Most of us don’t get epiphanies. We only get a whisper— only with time and understanding of self did I recognize the whisper‚ and connect the whisper to an answer I call wisdom. Of course‚ there’s never a single right answer. At some point‚ it feels right enough that I chose‚ and devote my time and energy to making my choice

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

The effect of time on enzyme reaction. Abstract: In this lab investigation we will observe how the amount of hydrogen peroxide is affected by catalase over time. The enzyme was added to 10 mL’s of hydrogen peroxide and observed over time to determine the relation between time and enzyme activity. The hypothesis stated that as time increased substrate would decrease. Therefore I predicted that at 60 seconds‚ there would be the least amount of H2O2. The enzyme activity mirrored my predictions

Many of the first textile mills and other factories were built in the New England region as there were a large number of fast flowing rivers which made it easy for the transportation of goods and they also had a large population. Later‚ Samuel Slater made many other spinning mills and also other factories in the Northeast side. Thus‚ the society turned into an urban society. This concentration of industries in the Northeast side had given ways to the development of transportation such as railroads

Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration
