Abstract: In this Lab we used the chemical DPIP to detect the rate of succinate broken down by the mitochondrial solution. We detected the amount of DPIP in the solution with a spectrophotometer and measuring the absorbance of light at the 600nm range. DPIP is a useful chemical to use in this experiment because it goes from a blue color when oxidized to a colorless liquid (Ogura‚ 281)‚ this is due to the hydrogen ions and electrons released during the transitional step between succinate and fumarate

synthesis‚ and in fireflies‚ also known as lightening bugs‚ bioluminescence (Biology Book). Bioluminescence is the process in which living organisms convert chemical energy into light (Branchini‚ 2008). In the fireflies case the reaction involves the enzyme luciferase which lights up a lantern-like mechanism under the tip the wings and attached to the end of the body of the firefly. It is presumed that the firefly uses the lantern to attract a mate. The goal in this experiment was to test the effect

Genetically Modified Organisms INTRODUCTION: The purpose of this lab was to identify if non-labeled food products are actually genetically modified foods. Before we could begin testing this theory we first had to gain an understanding about genetically modified organisms in general. This was rather easy because if you have been to any grocery store lately you have without a doubt seen products with labels saying "GMO-free" or even "contains only non-GMO ingredients." GMO actually stands for

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Introduction: Catalase is an enzyme‚ which is present in all life forms that utilize oxygen for their biological processes. Enzymes are proteins which increase the rate of reaction by decreasing the activation energy (the energy required to initiate a reaction). One of the main function of Catalase is to prevent the accumulation of hydrogen peroxide (H2O2) in the body by breaking it down into water and oxygen gas. Hydrogen peroxide is a toxic by-product of metabolic reactions. If hydrogen peroxide

catalyzed reaction Introduction: enzymes are complex chemicals that control reactions in living cells. They are biochemical catalysts‚ speeding up reactions that would occur too slowly to be of any usefulness to an organism. Although in organisms‚ it is not necessary for the reactions to be at maximum rate at all times. Enzymes interact with other molecules to produce a stable system in which the products are made when they are needed in the exact amount. An enzyme lowers the activation energy of
