    The objectives of this experiment were to investigate the activity of enzymes‚ components that influence the enzyme’s activity‚ identify an unknown phosphatase‚ influence of inhibitors‚ and determine if inhibition is competitive or noncompetitive. A spectrophotometer evaluated the measurement of color change over a period time due to product being formed. Determining unknown phosphatase and effects from different inhibitors were determined by varying the pH and substrate concentrations. The unknown

    Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

    potatoes affect the amount of oxygen produced with hydrogen peroxide and potatoes (enzymes)? Introduction The enzyme used for this experiment is Catalase. Catalase is inside mostly any living organism which uses oxygen. Its job is to break down hydrogen peroxide‚ into oxygen and water. (Formula) 2H2O2 ---> 2H2O + O2 (lab manual). There are limiting factors which if altered‚ can alter the procedure of the reaction‚ such as temperaturepH‚ and the concentration of either the enzyme or the substrates

    NOTES MAINTAINING A BALANCE • Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates. Enzymes are protein molecules that allow the body to engage in chemical reactions‚ such as metabolism. There activities can be catalytic (being able to control the rate of either increasing/decreasing chemical reaction) Enzymes have a specific shape‚ and this shape must be intact‚ otherwise the effectiveness of their

    Hypothesis The greater the length of the candle‚ the greater the burning time of the candle. IV. Experimentation Materials and Procedure 3 similar candles with different length 3 jars with same size Match Ruler Timer We made 3 set-ups for this experiment. Each setups has different length of the candle (Setup A has 2.5 cm‚ Setup B has 3.9 cm‚ Setup C has 4.8 cm). After that we lighted the candles‚ then we covered each of them with same size of jars. We waited for the fire

    The Effect of pH on Enzyme Activity A piece of Solanum tuberosum (potato) was removed and mixed with distilled water in a blender. The resulting solution was filtered through multiple layers of cheese cloth to filter out the liquid by eliminating any large pieces in the solution. The solution created was catechol. Five different solutions were prepared as blanks with each test tube containing 6.0mL of a different pH (pH 4‚ pH6‚ pH7‚ pH8‚ pH10) of phosphate buffer‚ 1.0mL of the enzyme and 1.0mL of

    Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

    ABSTRACT Enzymes are biological catalysts; they cause reactions to happen that would not normally occur due to the activation energy that would be required. They bring together substrates and cause chemical reactions that are essential for life. Without enzymes life processes‚ and life in of itself‚ would not be possible. Enzymes are also special because very little of the actual enzyme is actually used up in the reaction. In this lab two different factors‚ temperature and pH‚ were tested to see
