Effects Of Chemical Reactions On The Cell - 1654 Words

Introduction: When chemical reactions occur in the cell, enzymes, which are proteins, help catalyze the reaction (Schultz, D. L, 2005). Due to the fact that all enzymes are proteins, the folding pattern affects how the enzyme functions and if there is not proper folding then the enzyme cannot bind to substrates (Schultz, D. L, 2005). If there were no enzymes in cells, then the process of reactions would happen slowly. As said in Worthington Biochem, without enzymes, these reactions take place at a rate far too slow for the pace of metabolism. The reason why enzymes catalyze chemical reactions is due to the fact that enzymes lower the activation energy in the cell(Schultz, D. L, 2005). Activation energy is the amount of energy needed in a reaction. Every different type of enzyme is used for a specific molecule. Each molecule receives different signals that is why there is different enzymes for different molecules. Enzymes pair up with the substrate that matches and help carry on the reaction(Holum, J , Bennett, T. P., Frieden, E . . Harrow, B., Mazur, A. Martinek, R Pfeiffer, J). If there is more substrate added, the reaction rate will not be affected since there are not any enzyme molecules to react(Holum, J , Bennett, T. P., Frieden, E . . Harrow, B., Mazur, A. Martinek, R Pfeiffer, J). Two factors that interfere with the process of enzyme activity are different temperatures and pH changes. The reason behind that is because they are environmental changes.

There are many different issues that should concern us surrounding these toxic chemicals. The major concern is that many of these toxic chemicals have been claimed to be causing damage to the health of humans and even other life forms. Another concern is that most of the theses toxic chemicals have just recently been produced;Read MoreHow Does What We Eat Affect Our Brains?1449 Words   |  6 Pagesmechanism of action of many dietary nutrients still remains unknown or unexplained, the subject of concern to many. Effects are caused by excesses or deficiencies in certain chemicals, and can manifest themselves in various ways - current understanding suggests a myriad of ways in which dietary chemicals affect the brain. Many have the potential to alter the presence of various chemical signalling agents, and to alter hormone levels, which can affect behaviour, feelings, and our perception of the worldRead MoreBiological Reactions Of Chemical Reactions Essay1348 Words   |  6 Pagesthousands of chemical reactions that occur in an organism that make life possible. Most of these chemical reactions occur too slowly on their own. Enzymes are protein catalysts that speed up chemical reactions in a cell. Catalysts are not changed by the reactions they control, and are not used up during the reaction. Enzymes therefore, can be used over and over again. Enzymes are large complex proteins made by the cell and allow chemical reactions to take place at the temperature of the cell. TheseRead MoreEssay On Substrate Specificity Of Enzymes1119 Words   |  5 Pagesenzyme binds to its substrate at the active site of the enzyme, an enzyme-substrate complex is created. While in the complex, chemical reactions takes place and products are made. Enzymes have specific shapes that determine their functions. The shapes accommodate very specific molecules. Enzymes change shape after chemical reactions. There different energy changes with the reactions due to the state of the enzyme. The active site also changes shape when the substrate binds to it, thus allows for theRead MoreLab Report on Measuring the Rate of Conversion of Hydrogen Peroxide using Enzyme Catalysis664 Words   |  3 Pagesusing Enzyme Catalysis In essence, the main objective was to use chemical titration to measure and then calculate the rate of conversion of hydrogen peroxide (H2O2) to water and oxygen by using the enzyme catalase. Other purposes of the lab were; to measure the effects of changes of temperature, pH, enzymes concentration, and substrate concentration on rates of an enzyme. The lab was also an opportunity to see a catalyzed reaction in a controlled experiment. And the last objective was to learn howRead MoreThe Effect Of Enzymes On Chemical Reactions On The Body905 Words   |  4 Pagesconcepts to find out the different chemical reactions that take place in the bodies of living organisms and the influence of various organic substances in these reactions. The reactions are influenced by various enzymatic actions that are very important in the body as they help in activities such as the breakdown of substances for assimilation in the body. This paper explains the various processes taking place in the body and the effect of enzymes on chemical reactions in the body.

Metabolism is of the following two types: catabolism and anabolism. In catabolism, molecules break down producing energy During anabolism, synthesis of essential compounds needed by the cells are produced (such as DNA, RNA, and protein synthesis). Bioenergetics describes the metabolic pathways by which a cell obtains energy. Nutrition science studies the relationRead MoreToxic Response of Biological System732 Words   |  3 Pagesresponse of biological system Toxins are chemical, biological or physical substances that cause damage to an organism when they enter the biological system. These toxics can affect the entire system of the organism or just a substructure of the organism like cells or organs. Biological systems respond to toxins in various ways and this depends on many factors. Even though many toxic effects of foreign compounds are biochemically based, the way these effects are expressed may be very different.
