et al Abstract: The purpose of this lab was to determine how light affected photosynthesis‚ specifically the production of O2 bubbles. It was predicted that when the light was more intense the O2 bubble production will be high. Conversely‚ when the light was less intense the O2 bubble production will be lower. Basically the plant that is closer to the light will produce more bubbles than the plant that is placed farther away from the light source. In this lab the independent variable is the light

The students have studied that Hydrogen peroxide is a jeopardy to metabolism if it’s not obliterated. Enzymes are proteins produced by living cells of that act as catalysts which affects the rate of biochemical reaction by speeds up the breakdown of hydrogen peroxide into water and oxygen gas. The students have formed a hypothesis toward this experiment. If the speed of decomposition of hydrogen peroxide is related to the temperature then in high temperature it will speeds the decomposition of hydrogen peroxide. Materials ● Catalase

and poured into the Hydrogen peroxide filled flask. When the catalase and Hydrogen peroxide meet a reaction will occur and the hydrogen peroxide will be broken down into water and oxygen. The oxygen released from the reaction will be recorded by the Gas Pressure sensor. This step will be repeated five times for each necessary trial‚ then the next catalase extract will be

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

the safety‚ quality‚ consistency and strength of the color additive. Color additives are available for use in food as either "dyes" or "lakes". Dyes dissolve in water‚ lakes are the water insoluble form of the dye‚ are more stable than dyes‚ and are ideal for coloring products containing fats and oils. Allura Red AC is a red azo dye that goes by several names including: Allura Red‚ FD&C Red 40 and disodium 6-hydroxy-5-((2-methoxy-5-methyl-4-sulfophenyl)azo)-2-naphthalene-sulfonate. It is used as a
