Abstract: After reviewing the basics of enzymes and catalysis‚ we take a dive into the wonderful world of catalase. Beginning with establishing a base line of just how much hydrogen peroxide there is in 5.0mL of the reacted solution; to figuring out exactly how much actually reacted after 300 seconds of catalyzed reaction. Follow the experiment from the beginning steps right to the end as you see where the students went wrong‚ interpretation of the results‚ and great answers to work sheet

Clays are one of the important natural materials‚ which have been examined for catalytic applications. Clays are characterized by a layered structure and hence they are slippery when wet. They are broadly classified as cationic or smectite type (having layer lattice structure in which two-dimensional oxyanions are separated by layers of hydrated cations) and anionic or brucite type (in which the charge on the layer and the gallery ion is reversed complimentary to smectite type). Anionic clays are

Enzyme Catalysis Lab Problem: Before the lab‚ one should understand: • The general functions and activities of enzymes; • The relationship between the structure and function of enzymes • The concept of initial reaction rates of enzymes; • How the concept of free energy relates to enzyme activity; • That change in temperature‚ pH‚ enzyme concentration‚ and substrate concentration can affect the initial reaction rates of enzyme-catalyzed reactions; and • Catalyst‚ catalysis‚ and catalase

Sexual Addition may be a common problem but it still remains a relatively understood condition characterized by strong sexual urges. In recent weeks‚ the issue has resurfaced. Last week‚ a Journalist Brian Alexander(2007)‚ this psychological condition was once again questioned and the condition was described as such: "Sexual addiction is defined as any sexually-related‚ compulsive behavior which interferes with normal living and causes severe stress on family‚ friends‚ loved ones and one’s work

Name _____________________ Class ______________ Date _________ Addition and Resolution of Vectors Equilibrium of a Particle Overview When a set of forces act on an object in such a way that the lines of action of the forces pass through a common point‚ the forces are described as concurrent forces. When these forces lie in the same geometric plane‚ the forces are also described as coplanar forces. A single G G equivalent force known as the resultant force FR may replace a set of concurrent forces

Title: Preparation of Cyclohexene from Cyclohexanol Aim: To prepare an alkene‚ cyclohexene‚ by the dehydration of an alcohol‚ cyclohexanol‚ and better understand the processes that take place during this reaction. Introduction: One of the common ways of preparing an alkene is through the dehydration of an alcohol. In this experiment cyclohexanol is dehydrated to prepare cyclohexene while using sulfuric acid as a catalyst. A bromine test can be later done to ensure that the end product is

Addiction as Choice? Andria Burgess Introduction to Psychology Addiction as Choice? Substance abuse is a pervasive problem throughout the United States. It affects all populations‚ socioeconomic groups‚ ages‚ and races. Within the community of substance abuse treatment providers‚ there is an ongoing debate on whether addiction is a disease‚ or whether individuals who abuse substances choose to engage in the behavior. There is evidence to support both positions. This paper will examine

Premium Addition Triangle Pythagorean theorem
is a relationship between addition and multiplication. When you are multiplying you are simply adding the same number several times. For example 2*3 is the same as adding 2 three times‚ 2*3=6 which is the same as 2+2+2=6. Understanding the relationship between addition and multiplication contributes to the understanding of these concepts to the student because the student will be able to grasp the concept with more ease since they should have been experts in addition once they start learning multiplication
