    Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

    Calculation Process: The rate of respiration is calculated by dividing the distance that the drop of dye moved over 5 (period of time). For example‚ at 19 OC‚ the distance that the drop has moved after 5 minutes for the 3 trials are respectively 0.19‚ 0.10 and 0.13. The rate of trial 1 is then calculated by dividing 0.19 over 5‚ which is 0.0380 (shown above). For average rate of respiration‚ it is calculated by adding up all 3 trials of the same temperature and dividing the sum by 3. Additionally

    Discussion of Results and Scientific Explanation: In order to observe how much a chemical substance absorbs light a spectrophotometer can be used. A spectrophotometer measures the amount of light absorbed by measuring the difference in the intensity of the light before and after a beam of light passes through a sample solution. The area in which light is absorbed can provide information about the molecule‚ such as the concentration‚ by identifying the most preferentially absorbed wavelength.1

    This lab was split up into two different experiments‚ using different variables in each. During the first section of the lab‚ we investigated the what the effect of light is on both photosynthesis and cellular respiration. Our hypothesis about this effect was that the cuvette representing ‘no light’‚ being covered in foil‚ would result in a yellow CO2 indicator fluid‚ meaning that there was a decrease in pH and a high level of CO2 was present. Additionally‚ we hypothesized that the cuvette that was

    transport oxygen rich blood from the alveoli back to the heart. Inspiration (the process of inhaling) begins as the external intercostals and diaphragm contract. When this happens‚ the lungs expand. After this‚ negative pressure is used to facilitate respiration. So‚ air moves from an area of higher pressure‚ which is the air‚ to an area of lower pressure in the lungs and aveoli. During inspiration the diaphragm and intercostal muscles contract. The diaphragm moves downwards‚ while the intercostal muscles
