The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

My sister and I would stay up late just to watch CSI Miami and Law and Order. We would each try to figure out if that person

Introduction “The Enzyme Reaction” An enzyme is a protein that acts as a catalyst‚ which brings out a biochemical reaction. A Catalase enzyme‚ the enzyme tested in this experiment‚ is found in almost all living organisms that are exposed daily to oxygen (such as fruits‚ vegetables and animals). Background Information The Catalase enzyme in this experiment is known for being less affective the warmer the temperature is. According to “Science fair projects” an enzyme becomes unstable

Labset Five Worksheet 1. List five environments where you are likely to find microbial growth: Lakes‚ soil‚ oceans‚ tundras‚ deserts 2. How do microbes contribute to soil fertility? The decomposition that microbes take part in help release mineral nutrients‚ such as potassium and nitrogen‚ from dead organic matter and allowing primary producers the nutritional access. They also produce CO2 and CH4 to release into the soil and atmosphere. 3. Describe the growth you observed in each of your

Factors Affecting Reaction Rate Bob Jones Josh October 2‚ 2014 Period 3 Introduction: In reference to the collision theory‚ molecules act as small spheres that collide and bounce off each other‚ transferring energy among themselves when the collide. In order for a reaction to occur‚ there must be collisions between molecules. Through experimentation‚ factors are discovered that influence the reaction rates of chemical reactions include the concentration
