Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such

Investigating the effects of changing temperature on the activity of enzymes Background information: Renin is an enzyme that catalyses the coagulation of milk. It is found in the stomach of many animals and is used in making cheeses and junkets. It is found in the gastric juices or gastric mucosa of many mammals‚ including humans. In the human stomach‚ particularly those of infants‚ rennin works to curdle milk so that pepsin‚ another stomach enzyme‚ can further breakdown the proteins into absorbable amino

Observations of an Apple The assignment was to observe a fruit or vegetable for at least an hour. I thought it was crazy and pointless but not so ridiculous that I would not do it and earn a bad grade. Before I started‚ I read Samuel Scudder’s essay “Learning to See” where he talks about having to do a similar type of assignment but with a fish. He eventually became engrossed in the fish and so I became determined that I was going to try to find all I possibly could about my apple in the hour that

Introduction: Enzymes are biological catalysts that permit cells to carry out the many functions that are required in a living system. Every enzyme has a specific substrate and a specific function. Enzymes alter substrates one of three ways: by adding something to the substrate‚ removing something from the substrate‚ or by changing its conformation‚ otherwise known as its shape. The structure of an enzyme and its ability to function exists because it binds to an active site‚ thus increasing the

| [pic] Introduction Enzymes are catalysts which speed up a reaction by providing an alternative reaction pathway of lower activation energy. But they do not undergo permanent changes and so they remain unchanged even at the end of the reaction. Many enzymes consist of proteins and non-proteins called the cofactor. The intra- and intermolecular bonds that hold proteins in their secondary

INTRODUCTION Apples contain an enzyme called polyphenol oxidase (Phenolase). Phenolase has catecholase and cresolse activity‚ also containing small traces of copper. When apples are cut‚ phenolase is released from the cells and is exposed to oxygen. When phenolase reacts with oxygen‚ it catalyses one step of the biochemical conversion of phenolic compounds. The presence of oxygen hyrdroxylates the colourless phenols‚ which are subsequently oxidised to coloured quinones known as melanin. (Vlasta

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
