Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

After a holding period of 18 hours for winter captured crabs and a period of 30 hours for summer captured crabs‚ all individuals were transferred to containers with experimental temperature and salinity levels to begin the experiment. To observe changes due to salinity concentrations over the 48-hour period‚ groups of crabs were exposed to one of the eight salinity treatments‚ and temperature treatments were held constant at 5°C or 15°C to resemble winter or summer field conditions

Madison Ellis Clark Honors English IV Peggy T. Johnson May 20‚ 2014 Reflective Essay for Senior Service Learning Project For my project my classmate‚ Marie‚ and I worked together to beautify a part of the school. We chose to focus on the small nook near the English trailers and the art room. Here we found bushes being choked by vines and weeds‚ no budding flowers‚ dead branches‚ trash‚ and lots of nasty mulch. We knew we had a lot of work ahead of ourselves and not a lot of time (well‚ for

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

DESIGN AN EXPERIMENT: THE BIGGEST BLOWER EXPERIMENT Design an Experiment: The Biggest Blower Experiment Problem Statement: You have a pack of Hubba Bubba Bubble Gum. Does the amount of sugar in this gum affect the size of the bubble you blow?? Hypothesis: I think that sugar in any gum affects the size of the bubble you blow. I think this because I was watching “The Next Great Baker” and someone was melting sugar and when it cooled off a little he used a balloon blower to make bubbles out of

Design Experiment: Enzyme Inhibitors. Research question: What is the effect of adding lead nitrate solution on the activity of amylase enzyme? Aim: To test the effect of adding nitrate solution on the activity of amylase. Background Information: Inhibitors are molecules which repress or prevent another molecule from engaging in a reaction. They are substances that attach themselves onto an enzyme and reduce or prevent the enzyme’s ability to catalyse reactions. Competitive Inhibitors are inhibitors
