BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Tech Report by .... The SHAH 11 Daniyal Shah Wednesday‚ June 5th Planning: What is a Pop Bottle Rocket? A pop bottle rocket uses a 2L pop bottle‚ which then‚ you fill up the 2L pop bottle with water‚ and then with air‚ air pressure is created‚ and when you launch it Newton’s law happens. A lot of people put designs on their rockets‚ such as mine I did not leave it plain‚ I added cardboard‚ fins‚ color‚ nose etc. To make the rocket fly high and far away‚ you have to understand

Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical oxidation

Discussion The main findings of the present study were that the number of push up significantly in male than female‚ in contrast to the pulse rate‚ could be attributed at least partially to the greater aerobic fitness in male compared to the female students (see Figure 2). With thorough analysis of the results‚ the null hypothesis has been proven correct as there is no significant difference in the mean maximal pulse rate change of subjects who could do fewer than 20 push-ups and subjects

Field investigation of an ecosystem Located 20km out of Portland; Bridgewater Bay has many secluded rock pool locations that are accessible to biologists for investigation. In this experiment‚ the aim was to study small sections of a rock poll that contained a distribution of organisms. These organisms that were located were found in the littoral zone of Bridgewater’s rocky seashore. A littoral zone is made up of a community of aquatic organisms habiting the narrow strip of coast. The organisms

used to purify solid organic compounds. Using the recrystallization technique‚ a solid compound is dissolved in a solvent and the compound slowly crystallizes as the solution cools. Using a filtration technique‚ a pure solid is produced when the molecules of the impure particles in the compound are excluded from the crystal lattice. After obtaining the pure compound‚ a melting point determination procedure can be done using a mel-temp device to correctly identify the compound if its identity is

Photosynthesis and the Amount of Light _______________________________________________________________________ I. Introduction Photosynthesis the process where plants use sunlight (energy) to synthesize foods forming the products carbohydrates and water (H20 + CO2 + Light CH2O + O2). For photosynthesis to take place they need water‚ carbon dioxide and light and chloroplasts. Light is absorbed inside he thylakoid
