displays a positive slope‚ thus dictating a positive relationship between catalase concentration and the rate of reaction. This means when catalase concentration increases‚ the rate of reaction also increases. In other words‚ at 20% catalase concentration‚ the rate of reaction was only 4.220 mm/s while at 100% catalase concentration‚ the rate of reaction was 7.704 mm/s. This proves the positive correlation between catalase concentration and the rate of reaction. This occurs because as the enzyme

Abby Goldschmidt Honors Biology 2° Mrs. Gempel September 3‚ 2015 Daphnia Lab Results Paper Abstract The goal of the study was to observe the effects of multiple chemicals on a Daphnia magna’s heart-rate compared to a control (pond water). The different chemicals were caffeine and alcohol. The heart-rate was the main variable in this experiment. The Daphnia’s heart-rate was observed for 15 seconds and then multiplied by 4 to show its heart-rate in one minute. This was repeated 4 times for each

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight‚ hearing these could be attributed to loud noises or too much light going into your eye

Abstract For the amount of aspirin in a commercial tablet to be determined‚ different solutions of acetylsalicylic acid mixed with NaOH were created at different concentrations. All the different solutions were then analysed using Novaspec photometer‚ which allowed for a graph to be created and a line of best fit to be made. The amount of aspirin in a commercial tablet was found to be 350mg. Introduction The molecular formula for aspirin‚ also known as acetylsalicylic acid‚ is C9H8O4. It is most

Ashley Esparza Stallings Period 2 January 26‚ 2013 Enzyme Catalysis Lab Report Background: Enzymes are catalyst‚ which affect the rate of a chemical reaction. One consequence includes the cell to carry out complex chemical activities at relatively low temperatures. In these reactions the substrate binds reversibly to the active site. The cause of this is a decrease in the energy needed to activate the reaction of the substrate molecule to from products. Every enzyme is particular for a

AP BIOLOGY Lab 5 Cellular Respiration Objective: To calculate the rate of CR from the data. To then relate gas production to respiration rate. Then test the rate of CR in germinating versus non-germinating seeds in a controlled experiment and then test the effect of temperature on the rate of CR in the germinating versus non-germinated seeds in a controlled experiment. Analysis: 1. The CR is higher in the germinating peas in the cold water rather than in the beads or non-germinating peas
