Tetrapyrrole compounds: chlorophyll and heme groups By Erwin Lim 1. Tetrapyrrole compounds A tetrapyrrole compound is a chemical group that consists of four pyrroles that are joined together by covalent bonds‚ forming a porphyrin ring. They are naturally occurring pigments‚ which are used in many biological processes (Berg‚ 2009). The basic structure of a tetrapyrrole is as seen in Figure 1‚ while the basic structure of a pyrrole is as seen in Figure 2. Figure 1.Tetrapyrrole Compound (Berg

IDENTIFICATION AND CLASSIFICATION OF PARAMETERS THAT MEASURE FITNESS OF EACH PRODUCT I. INTRODUCTION Potato is a cool-season vegetable that ranks with wheat and rice as one of the most important staple crops in the human diet around the world. The white potato is referred to as the "Irish potato" because it is associated with the potato famine in Ireland in the 19th century. Potatoes are not roots but specialized underground storage stems called "tubers." Maximal tuber formation occurs at soil

changed. You will observe how changing factors like temperature‚ pH‚ substrate concentration‚ and enzyme concentration changes the rate of an enzymatic reaction. In this experiment you will act as an enzyme by breaking toothpicks witch act as substrates. After observing the results of this experiment you will be able to determine what causes the fastest enzymatic reaction. Methods and Materials The materials needed for this lab are 240 toothpicks and a timing mechanism. To start you should divide

progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site is the region of the enzyme where binding to the substrate occurs. This site is flexible‚ and can reform to assist with the catalyst of the reaction

experiment. The purpose of this experiment was to prepare whole as well as broken preparation of mitochondria and compare the enzymatic activity of succinate dehydrogenase (SDH) and malate dehydrogenase (MDH). This experiment will answer the question of whether enzymatic activity will be greater in intact or broken mitochondria as well as in SDH or MDH. It is hypothesized that enzymatic activity will be higher in intact mitochondria because the intact mitochondria contains both SDH and MDH‚ where the broken
