for each tube‚ containing different levels of pH. Tube 2 had an acidic pH level‚ Tube 3 had a neutral pH level‚ and Tube 4 had a basic pH level. It is indicated that the absorbance rates were the highest for the neutral pH level‚ with a final absorbance rate of 0.166. This was followed by a basic pH (0.106). The acidic pH level had the least amount of absorbance with a final absorbance rate of 0.069. This reinforces the idea that the ALP enzyme worked best under conditions with a neutral pH and worked

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

Method: 1) The materials for the practical were collected. 2) We set up a clean cutting area which consisted of placing newspaper onto the bench followed by the cutting tile on top. The liver was then cut into 1 cm cubes. 3) A 1 cm cube of liver was placed inside a 250mL measuring burette‚ we then added 9mL of

Period 1 10/14/12 Enzyme lab Enzymes are biological catalysts that speed up the process of chemical reactions. They are also proteins‚ and most enzymes activities occur within organism. They decrease activation energy‚ energy that is needed to start a chemical reaction. Enzymes are substrate specific substrates ending in "-ase"‚ enzymes ending in "-ase". External factors‚ such as temperature‚ pH‚ and concentration of the substrate‚ affect the enzymes activity in the lab‚ pectase and cellulase

Biology has been the most interesting and appealing subject I have taken. Taking the course as a freshman‚ and the AP course as a junior‚ has really influenced my choice of a potential major. The course taught me how to be more studious and efficient with the information I retain. It is a puzzle‚ in which you piece together process by process‚ step by step. AP Biology also enhanced my collaboration skills. The course is very rigorous and challenging‚ and I struggled often trying to do it all by myself
