Control Tube
678 wordsIntroduction: Respiration commonly known as the inhalation and exhaling or breathing has a more little known definition. This is the definition that involves the cellular level of eukaryotic cells. Cellular respiration may best be described by the following equation: C 6 h 1206+602-6 CO 2+6 H 20+36 ATP. ATP that is the energy needed for a cell to function as part of cellular respiration. ATP is needed to power the cell processes. If cells are denied energy they will die. The second law of therma...

New Tubes
419 wordsIntroduction Chitobiase, from Vibrio harvey i, is a membrane bound lipoprotein involved in the degradation of chitin. Chitobiase is similar to and may share a common ancestry to the a-chain of human b-hexes-aminidase. Chitobiase is encoded by chb. In this experiment, a restriction map for restriction enzymes Eco R 1, Pst 1 and Hind using Southern hybridization and restriction analysis of pRSG 192. pRSG 192 is a recombinant plasmid derived from the chb gene and pUC 19, a 2.7 kb engineered plasmid...

Test Tubes 5 Fermentation Tubes
766 wordsPlanning PROBLEM TO BE INVESTIGATED Yeast enzyme specificity: Specificity of Brewers and Bakers yeast enzymes to different sugars (being monosaccharides) HYPOTHESIS I predict Bakers yeast to have a different enzyme specificity compared to Brewers yeast where more CO 2 is produced at 37 0 C. BACKGROUND KNOWLEDGE Fermentation is the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration). It involves a culture of yeast and a solution of sugar,...

Experimental And The Control Test Tubes
2,926 wordsMaterials and Methods The first experiment involved examining the effect of temperature on aerobic respiration of germinated pea seeds. The students testing the effect of temperature, will be divided into two groups. The first group is Student Pair A. They will test the effect of 10 C, 20 C and 30 C temperatures on pea respiration rate. The second group is Student Pair B. They will test the effect of 40 C and 70 C temperatures on pea respiration rate. For both groups, the first procedure calls f...

Glass Tube Into A Measuring Cylinder
3,319 wordsHypothesis This investigation starts by investigating the effect of the length of glass tube on the rate of flow of water out of it. The volume per second of the water flowing out of the tube (rate), is determined by the forces acting. The pressure force pushes the fluid through the pipe against the resistance of the viscous force. Therefore I would expect a longer glass tube to create more force opposing the movement of water and therefore produce a slower rate. In this experiment I expect to f...

Set Up The Fermentation Tubes
1,041 wordsFermentation InvestigationPlanningAs a culture of yeast is merged with solution of sugar, a reaction called fermentation occurs. As products, ethanol and carbon dioxide are produced, in form of liquid and gas respectively. The reaction follows this equation: Glucose solution + Yeast Carbon dioxide + Ethanol + (Energy) And as one of the products is in the form of gas, the volume of the product can be measured to demonstrate the difference of the reaction when certain factors are changed. In the o...

Top Notch 3 Inch Tubes
552 wordsEvery year, America celebrates many holidays with fireworks. One of the most popular selections is a Roman Candle. If you want to try to make this at home, common pyrotechnics stores have all the supplies you would need. Just think of the "oohs" and "a 's" when you light off your homemade fireworks at home. First of all, you need a sturdy, good tube. The tube should be cylindrical and should be at least 3/32 of an inch thick. The opening at the top of your tube should have a 5/8 inch opening. Th...

Gel Filtration Chromatography
392 wordsThis lab's topic was Gel Filtration Chromatography. Chromatography is a technique used to separate molecules on the basis of differences in size, shape, mass, charge, solubility and absorption properties. A specific kind of chromatography is gel filtration. This technique separates molecules on the basis of their size. This procedure is performed by passing molecules down a solution containing beads made of a polysaccharide or polyacrylamide gel with semi-uniform pores. All of the beads have the...

1 4 Inches O.D. Rod
472 wordsA dipole is a balanced antenna and should not be fed directly with coaxial cable. Doing so would cause the outer conductor of the coaxial line to act as part f the antenna, and a large amount of signal would be radiated or received by he outer conductor. For casual reception his may not matter much, but the directional radiation pattern of the antenna is destroyed and reception / transmission results are no longer predictable. In order to derive a balanced feed for the dipole some sort of a tran...
