temperature‚ pH‚ and the presence of inhibitors. Catalase is an enzyme which is produced by every cell to break down hydrogen peroxide. Hydrogen peroxide is a waste product of cellular activity that is poisonous to cells. Catalase speeds up the decomposition of hydrogen peroxide into harmless water and oxygen gas. The purpose of this lab was to determine whether an inhibitor affects the rate of activity for the enzyme catalase. Since catalase speeds up the production of oxygen gas‚ the rate of enzyme

Introduction: Everyday thousands of chemical reactions happen in our bodies. These reactions produce the energy for our bodies to use. During these chemical reactions there are enzymes‚ biological catalysts‚ which help speed up metabolic reactions by lowering the energy barriers without being used up or altered in the reaction. (Campball‚ 2008) Every enzyme has an optimum pH at which it is most active. An increase or decrease in the pH of the solution will cause the enzyme to have a change in its

moved‚ skin slid away from the underlying connective tissue. What is the normal function of connective tissue? It protects and supports the body and its organs. Would the slippage of the dead man’s skin be due to decomposition of cell junctions or underlying connective tissues? Decomposition of cell junctions. C. Would the bruises on the dead man have formed in the epithelia or in the underlying connective tissues? Explain your answer. Underlying connective tissues because bruises form underneath the

MARKETING Through SOCIAL MEDIA: ADVANTAGES AND DISADVANTAGES 1. Introduction The absence of Internet-based social media has made it possible for one person to communicate with hundreds or even thousands of people around the world. Social media has exploded as a category of online discussion where people create content‚ share it‚ bookmark it and network at vast rate. All types of social media provide an opportunity to present oneself and one‟s products to dynamic communities and individuals that

Invertible matrix 1 Invertible matrix In linear algebra an n-by-n (square) matrix A is called invertible or nonsingular or nondegenerate‚ if there exists an n-by-n matrix B such that where I n denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication. If this is the case‚ then the matrix B is uniquely determined by A and is called the inverse of A‚ denoted by A −1 . It follows from the theory of matrices that if for finite square matrices A and B

WE tend to forget that our lifestyle and mindset have largely been influenced by our colonial past. The British influence has changed the way we look at ourselves and has stripped us of a confidence that comes naturally to a people belonging to an ancient and great civilisation. Colonisation coerces people from subordinated culture to denigrate themselves. A kind of a virtual reality is created to expedite this attitude of self-hate among the native population. An alternate reality is created

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test
