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

is lactose-negative. 15. C. Citrate test 16. the citrate test will differentiate E. coli from Klebsiella. Normally a battery of test would be performed to separate the numerous species in the family Eneterobacteriaceae. 17. B. The bacteria are citrate-negative. 18. the tube started off with the same green color‚ so no change occurred. This is in contrast to the tube on the bottom that was inoculated with a citrate-positive bacterium. this means that colony type 2 is normal E. coli

Bacteria and Archaea The Archaea are presently recognized as one of the two main domains of prokaryotes. The majority of genes that indicate Archaea to be different from Bacteria are for information transfer processes such as DNA replication‚ transcription and translation. Of these‚ DNA replication machinery appears to be most different between the two domains. In terms of transcription‚ the core subunits of the RNA polymerase are the same in Bacteria and Archaea‚ but archaea also contains several

Formal Lab Report | Chemistry | | Student name: Sara Hattar Grade: 10 ”C” | | Teacher: Christine Ziadat | | | Title: Investigating the effects of changing the concentration of an acid on the rate of reaction between HCl and Magnesium. Aim: In this experiment we are going to see the effects of using three different concentrations of HCl when added to Magnesium metal on the rate of reaction. Hypothesis: If the concentration of the acid increased in reaction between HCl (the acid)

Biology Laboratory Report MEASURING RATE OF WATER UPTAKE BY A PLANT SHOOT USING A POTOMETER Introduction All plants need salts minerals‚ water‚ CO2 and O2. To fulfill their requirements different plants use different ways. Lower plants use diffusion‚ however higher plants use vascular tissue that is located in the middle of the root and in the vascular bundles in the stem. The transpiration is the important process in the plant. The main reason is that transportation

Isolation and Identification Microbiology 521 2/10/12 Purpose: The purpose of this experiment was to enrich Pseudomonas bacteria‚ isolating a species of Pseudomonas and identifying it using phenotypic properties and DNA sequencing as an existent or completely new and undiscovered species of Pseudomonas. Overview: Genus Pseudomonas is a chemoheterotrophic bacteria found in soil and water. They are Gram negative‚ motile‚ paired rods that are also oxidase-positive. Pseudomonas species are

Microscope lab report Introduction Microscope is a tool used to enlarge images of small objects that are hard to study with bare eyes. The compound light microscope‚ which is going to be used in this lab activity‚ is an instrument with two lenses and various knobs to focus the image. In this lab‚ we will learn about the proper use and handling of the microscope. Objectives: •Demonstrate the appropriate procedures used while using the compound light microscope correctly. •Make and use a wet mount

The particular conditions that had to exist for this to apply were that the population had no mutation‚ had no natural selection‚ was a large population‚ had only random mating‚ and had no migration. For the cases to follow later in the lab‚ Cases 1 and 2 exemplify Hardy-Weinberg conditions. All of the others either have selection or not enough members in the population‚ which will be the most-closely observed

In the lab‚ we use a Biological Media to aid in growth reproduction. Also referred to as a culture medium‚ a Biological Media is a substance used to support the growth of microorganisms. The two types of media most commonly used in Microbiology are selective media and differential
