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)

Anatomy of Flowering Plants Tissues A tissue is a group of cells having a common origin and usually performing a common function. Based on cell’s capability to divide‚ tissues are classified into two main groups which are as follows: 1. Meristematic and 2. Permanent tissues. Meristematic Tissues: Cells in the meristematic tissue are capable of dividing. Meristematic tissues are found in those regions which need to grow continuously. For example‚ root tips and stem tips contain meristematic

If you take a look at the paintings‚ you will see that they are abstract. In fact‚ they are painted in a style that is sometimes referred to as "Abstract Expressionism". Many people have trouble understanding and appreciating this type of art. The purpose of this essay is to explain how‚ over time‚ art has evolved to become more and more abstract‚ and why this is important. My intention is to explain the goals of abstract art‚ and to help you learn how to enjoy it. To begin‚ I’d like to introduce

Abstract Expressionism The term Abstract Expressionism was used for the first time in 1919 to describe the work of Kandinsky‚ but is now used to define some post world war two art. In the 1940’s in America‚ particularly New York artists were creating art in a new style one that shifted the art world’s focus. Though they were not formally associated‚ these artists all shared some common ideas. This group was referred to as "The New York School" or "Abstract Expressionists". This type of art

protein structure would be tertiary‚ or quaternary. (b) Discuss how the structure of a protein affects the function of TWO of the following. • Muscle contraction • Regulation of enzyme activity • Cell signaling Enzymes bind to their substrates at a specific point called the active site. The regulation of enzyme activities mostly involves the inhibition of substrates‚ and this inhibition is divided into two types. The first type‚ competitive inhibitor‚ binds the inhibitors at the active site

substrate concentration‚ the enzyme is working at “maximum efficiency.” With a concentration at 40‚ it produced 2‚339 products. 2. The maximum velocity of a reaction is reached when the active sites are almost continuously filled. Increased substrate concentration after this point will not increase the rate. The reaction rate increases as substrate concentration is increased. It will soon level off though. 3. When the concentration is at low substrate‚ most of the enzyme molecules are not filled
