Purpose: To find how pH and temperature levels affect the enzyme Background: Enzymes are a type of protein vital to sustaining life‚ it works with vitamins and minerals as a biological catalyst‚ which lowers the activation energy for a reaction to occur. Each individual type of enzyme does a specific job‚ and they do not die‚ they are reused. For example‚ catalase is an enzyme found in almost all living cells that will break down hydrogen peroxide and turn it into water and oxygen. The

Organizational Approaches to Change The ability to change and adapt is extremely important for any organization to reach its full potential. Influencing people to change is more dependent on showing them a truth that influences their feelings‚ rather than shifting their thinking (Kotter & Cohen‚ 2002‚ p. 1). If leaders can change the behavior of members of an organization‚ the successful large-scale change they are seeking will more likely be realized. According to Kotter and Cohen‚ in order to

to identify two unknown organisms. PROCEDURE I was given unknown #76. I performed the streak plating method with my unknown organisms. To perform this exercise I needed a TSA plate and labeled the bottom of it with my name‚ group number and organism. I also divided the bottom into three sections. After that‚ I sterilized my inoculating loop using the bunsen burner flame. After letting the loop cool‚ I reached into my unknown test tube with my loop and grabbed the organisms. After that I streaked

Model organisms are organisms used for research. They are alive‚ non-human species used for the purpose of studying different human diseases or other related experiments in which human testing would be considered either unsafe or unethical. Scientists study a particular biological phenomenon on a model organism and try to relate their findings to other types of organisms that are more difficult to study. As an example‚ 60% of human disease genes have an equivalent in the fruit fly and nematode worm

The Human Being—A Complex Organism Human beings are complex and special organisms as there is a complex organisation of cells in the human body. The organisation in the human body is summarised as follows: Cells—> Tissues—> Organs—> Systems—> Organism. The same type of cells which carry out a specific function are organised into a tissue. For examples‚ a group of muscle cells form a muscle tissue while a group of nerve cells form a nerve tissue. They are organised to work together to perform

Organism Physiology The course in which different kinds of living organisms are thought to have developed from earlier forms during the history of the earth is defined as Evolution. Many time organisms evolve due to environmental changes. To better understand evolution this paper will review a diagram of an organism and explain how the organism has evolved physiologically to become suited to fit its environment. Organism To understand the evolution of an organism it is important to understand

The Complement System The complement system is a nonspecific defense mechanism activated in response to invading organisms. This system gets its name from the fact that it complements the action of antibodies. It is the primary mechanism activated by antibodies to kill foreign cells by forming membrane attack complexes. In addition to directly lysing the invading organisms it also reinforces the general inflammatory tactics. It can be activated in two ways: 1. A nonspecific innate immune
