Analysis of the Enzyme Sucrase for Optimum Temperature, pH, and Concentration

- Analysis of the Enzyme Sucrase for Optimum Temperature, pH, and Concentration ABSTRACT Enzymes react differently under different conditions and concentrations, being the most productive at the enzymes specific optimum condition and concentration. The enzyme sucrase, extracted from yeast, breaks down the complex sugar sucrose into the simple sugar glucose. Testing for sucrase’s optimum environment, multiple reactions were ran using varying amounts and concentrations of sucrose and sucrase at different pHs and temperatures....   [tags: Biology]

Temperature's Affect on Chemical Reactions

- There are many factors that affect the products of chemical reactions. All reactions are affected in a different way when exposed to these agents. Temperature is just one of many factors that can change things about reactions. When exposed to temperature change, the activation energy of a reaction can be met much more quickly (or slowly) than it would have been. As the temperature goes up, the rate of reaction increases. Temperature is a very flexible contributor to the rate of reactions and chemical reactions in general....   [tags: activation energy, physical chemistry]

Temperature And Sucrose Concentration For Yeast Fermentation

- In our Yeast Fermentation Experiment, my group and I investigated the optimal temperature and sucrose concentration for yeast fermentation. To test for the optimal temperature for yeast fermentation, we measured the amount of CO2 that was produced inside fermentation tubes that were heated to varying temperatures. By measuring which temperature produced the most CO2, we were able to determine that 60 degrees Celsius was the optimal temperature for yeast fermentation to occur. We tested for optimal sucrose concentration the same way we did for optimal temperature except we used varying amount of sucrose instead of varying temperatures....   [tags: Yeast, Ethanol, Fermentation, Bacteria]

Found commonly in tropical waters less than deep, these areas have a high availability of nutrients and access to sunlight required for the process of photosynthesis. Coral reefs are amongst the most complex and bio-diverse ecosystems, spanning approximately 284,300 km2 (Spalding & Ravilious et al., 2001) providing a home for 25% of all marine life....   [tags: marine environment, oceans, global temperatures]

The Effect Of Heat Transfer On Temperature

- 1.1 GENERAL BACKGROUND Heat transfer is by virtue thermal energy stored in temperature-dependent motion of particles. The exchange of kinetic energy of particles occurs through the boundary between two systems which are at different temperatures from each other or from their surroundings. Heat transfer constantly occurs from a region of high temperature to the region of lower temperature. Heat transfer changes the internal energy of both systems according to the Thermodynamics. The Second Law of Thermodynamics defines the concept of thermodynamic entropy....   [tags: Heat, Thermodynamics, Temperature, Heat transfer]

- Discussion The test scores of the participants in the study did not vary enough to warrant a conclusion of the effects of temperature and music on the retention rates. There was a tendency for those in the warmer conditions to have a more positive attitude and, possibly because of this slightly improved mood, to score higher on the retention test (Appendix B Figures- 7&8).

The Effect Of Temperature And Microwave Radiation On Enzymes

- The article talked about the effects that stresses, such as temperature and microwave radiation, have on enzymes, most importantly in the effect of denaturing enzymes. The purpose of the article was to examine if a certain type of charcoal, termed biochar, could stabilize soil enzymes after these had been under denaturing stress. Also, the biochar was used to determine if water concentrations could be maintained under the stresses already mentioned. The particular type of method that was used to determine how biochar would aid the enzymes was by placing soil in different vials with different concentrations of the biochar, ranging in concentrations of 0, 1, 5, and 10 percent....   [tags: Enzyme, Temperature, Microwave oven, Energy]

Both experiments showed the same relative trend of increased movement in a warm environment as opposed to decreased movement in a cold environment. Both trials had a much greater mean distance travelled over one minute in the warm environment than they did in the cold environment.

The Effect Of Temperature On The Temperature Operating Spectrum

- The temperature operating spectrum varies from 2 to 80 °C, although practically, in the study of biomolecules, a narrower range of temperatures is used (usually from 10 to 35 °C). During an experiment cells are filled with liquid, with the reference cell used as a reference that usually contains water and the second cell (sample cell) contains the sample. The temperature is set by the user and is maintained at the same level between the cells and the jacket by heaters (resistances). The whole system is based on the constant power that is supplied to the reference cell, which in turn enables or disables the heater on the sample cell and provides a baseline power signal, the DP (differential p...   [tags: Thermodynamics, Entropy, Internal energy]

The History of Temperature Scales

- Temperature is thermodynamic property of objects. It is an “indirect measure of the kinetic energy of the particles that make up matter” (Lerner 2008). Temperature determines the direction of the flow of energy between two objects. When they are put in contact with each other, the faster-moving molecules of higher temperature object will collide and increase moving speed of slower-moving molecules of the lower temperature object. This process stops when both objects have the same average molecular kinetic energies, or in other words, they are in thermal equilibrium with each other....   [tags: fahenheirt, celsius, kelvin, rankine]

Temperature Affects On The Water Quality

- Temperature Temperature affects various processes in the water quality (ANZECC 1992). The rate of chemical reactions, for example, is activated when high water temperature occurs which causes evaporation of certain substances that may be present in the water. Also, as water temperature increases, the solubility rate of gases in water, such as oxygen (O2), decreases and respiration rates of aquatic organisms increases which results to greater oxygen consumption (Chapman and Kimstach 1992). A change in water temperature also causes greater destruction of aquatic life and problem of unwanted growth of water plants and wastewater fungus (Metcalf and Eddy 1991)....   [tags: Water, Oxygen, Water pollution, Aquatic ecology]

Heat and Temperature Essay

- Relation of Heat and Kinetic Theory of Matter 1 The Kinetic Theory of Matter declares that particles of matter in all states are in vigorous motion. And this theory can help us predict heat transfer. Unmistakably the transfer of heat is the kinetic energy caused by the jittering of atoms or molecules in a substance. The faster the particles move, more heat is produced and the farther apart the molecules can spread. This theory explains heat transfer by conduction. Thermal energy flows from the warmer object and through the cooler one warming it up....   [tags: Physics]
