Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction affects by substrate concentration:

Positive Effects of Volcanos Volcanic activity has many positive impacts on both the natural physical environment and on socio-economic activity. Positive impacts include the creation of new land‚ the creation of valuable natural minerals and ores‚ and the enhancement of countries’ tourism potential. Creation of new land: Volcanic activity can result in the creation of new land‚ when material from within the earth’s crust is ejected in the form of molten liquid‚ then cools and solidifies to created

Investigation Into The Effect Of PH On The Activity Of Potato Tissue Catalase Aim The aim of my investigation is to see how pH affects the activity of potato tissue catalase‚ during the decomposition of hydrogen peroxide to produce water and oxygen. Catalase + 2H2O2 Catalase + 2H2O +O2 Catalase + Hydrogen Peroxide Catalase + Water + Oxygen Independent Variable The independent variable in this investigation is pH. Each individual enzyme has it’s own pH characteristic

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

courses offered by an educational institution”. In the world of education‚ do extracurricular activities still matter? Well‚ they are definitely a way to escape boredom as they strive to challenge an individual to do something new by overloading or filling up his schedule. And in truth‚ there are some anecdotes on different individuals cracking under pressure due to their participation in these activities. However‚ they cannot compare to the countless rewards that these ventures have to offer. After

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

The effects of the school activities to the learning achievement of the selected fourth year students of Liceo de San Pedro Academic Year 2009-2010. School activities are those sponsored by and usually held at school but that are not part of the academic curriculum. They often involve some time commitment outside of the regular school day. A school activity serves as a break of the students from their lessons. School activities include both extracurricular and co-curricular activities. School

Enzymes- reduce the amount of energy required for the reactions they catalyse [accelerate]. -thus‚ increasing the rate of reactions that occur in living organisms. WITHOUT enzymes : metabolism would be so slow at body temp. that insufficient energy would be available to sustain life. -Many enzymes are “Intracellular”- used within the cell that produced them e.g. enzymes in respiration & photosynthesis -Others are “extracellular”-they act outside the

All economic activities affect the environment in some way whether it is done intentionally or unintentionally. These could be positive or negative effects. Most of the time‚ they are negative. Most activities usually end up harming ecosystems or just polluting the environment. Economic activities can range from mining all the way to farming. This essay will discuss different types of economic activities and how they effect the environment. The first effect on the environment is the over harvesting

The Activity of a Protease (Trypsin) Introduction Enzymes catalyze reactions by creating alternate reaction mechanisms whose transition states are more thermodynamically stable than uncatalyzed reactions (Berg et al.‚ 2002; UBC Department of Microbiology and Immunology‚ 2006). Increased thermodynamic stability in these transition states reduces the energy of activation‚ the minimum amount of energy input a chemical system requires for a reaction to occur (UBC Department of Microbiology
