One can predict that the tube with the highest concentration of yeast will produce the most carbon dioxide and will have the fastest rate of alcoholic fermentation. Results Two separate experiments were conducted to determine the effect of yeast concentration and pH level on the rate of fermentation. The first experiment involved the placement of different concentrations of yeast‚ glucose‚ and distilled water in four different tubes. Pipette pumps were

specific conditions to function‚ thriving at temperatures between 29°C-40°C‚ with an optimal temperature of 37 °C. Above 37°C‚ rennin molecules increase in energy causing the rate of reaction to increase‚ becoming denatured at approximately 60°C. Below 37°C‚ the reduced energy level results in fewer collisions and the rate of reaction and activity of rennin decreases. (7) The optimum pH for rennin is pH 3.4 (8) as it mimics the gastric juices and acidic conditions of the stomach‚ however again rennin

The purchasing management Purchasing management directs the flow of goods and services in a company and handles all data relating to contact with suppliers. Effective purchasing management requires knowledge of the supply chain‚ business and tax laws‚ invoice and inventory procedures‚ and transportation and logistics issues. Although a strong knowledge of the products and services to be purchased is essential‚ purchasing management professionals must also be able to plan‚ execute‚ and oversee purchasing

the water diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the 5 minutes given‚ giving a more pink/red color to the water surrounding the beetroot at a higher temperature‚ and at lower temperatures slowing down the molecules and making the rates of diffusion lower in colder temperatures‚ giving it a paler appearance

This experiment focuses on the effect of light intensity on the rate of photosynthesis. In simple terms this refers to how the production rate of the products of photosynthesis (oxygen and glucose) will be affected by a light source at different distances. The hypothesis states that “If there is a higher light intensity‚ then more oxygen and glucose molecules will be produced‚ and the rate of photosynthesis will increase.” This hypothesis was accepted. This was determined by counting the number of

How Values Affect Decisions in Personal and Professional Life Shaundrea Sager University of Phoenix Abstract Many people have a set of core values‚ either personal‚ organizational‚ or cultural‚ that help guide his or her life‚ and that assist him or her in making decisions in their everyday existence. Most of my decisions are based on how they will affect my family‚ me‚ and my career. My family is the key factor in any decision I make. I have to consider what influence my

analysing the graph‚ you can see that there is a relation between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size

heat. If an enzyme has been denatured it means the shape has been altered therefore cannot perform its function‚ many factors can cause this including high heat. The hypothesis is if temperature is increased the amount of activity rate will increase. The results for the rate of oxygen production (dependent variable) will increase as the heat increases. The reason is a chemical reaction to the heat gives it energy. Enzyme reactions are important to life because “Enzymes are proteins that control the
