Background Research Enzymes are biological catalysts, they have optimum pH values and temperatures, their activity is greatest while in optimum. Enzymes are also proteins, if the shape of an enzyme changes, it would no longer work. Enzymes are substances that fasten the chemical reactions in the human body. Enzymes are proteins that make up shapes in order to allow smaller molecules to fit into them to increase the chemical reaction rate. Although enzymes are made by living thing, enzymes are…

Fluid regulation is very vital to homeostasis. If electrolyte levels rise or fall beyond normal limits, many bodily functions will eventually fail to progress at their normal degrees. Maintaining normal pH levels is also important for normal body functioning mainly because small alterations in pH can make up important changes in our metabolism. Electrolytes are minerals which mean that they carry ions and salts in our body that have an electric charge. They can be found in our urine, blood…

central location of the fish kill site, the salinity level should be between 0.5 to 35 ppt. The typical pH range for an estuarine system is between 5 and 9, which is the range most finfish populations adapt to live in (pH, 2012). The main chemical species responsible for affecting the pH include the levels of oxygen and carbon dioxide (pH, 2012).…

A different type of Japanese bamboo had been studied by Phong et al. (2012). Moso bamboo was harvested and processed using several methods to obtain the fiber. In alkali extraction method, the bamboo was cut into thin slabs with length and thickness of 25 cm and 3 mm, respectively. The slabs were immersed in different concentration NaOH solution (1%, 2%, 3%) at 70 ⁰C for 10 h. This study showed that only 1% NaOH resulted in higher mechanical properties. The roller looser was then used to produce…

for pancreatic lipase is lipids or triglycerides. Hydrolysis of triglycerides occurs in the duodenum and the PH rages are from 7.1 to 8.2. • Phenol red was used as a PH indicator of the samples. if the sample is an acid then a yellow color is appeared, if the sample is alkaline then a red color will appeared. if the sample is neutral, it will be orange or if the sample is alkaline and has a PH of 10 or less, then it will have a pink color. Table 1 - Result of Lipid Digestion with…

just under 15,000 gallons of water. Once organisms swim into a mesocosm, they are sealed and the pH of the water is lowered to predicted pH level of 7.8 at the end of the century. A pH of 7.8 has been observed to slow some fish larvae growth and present abnormal behavior within species. Some abnormal behaviors from species including clown fish and sea snails were observed swimming toward predators. The pH of the solution is lowered by introducing carbon dioxide into the solution. Another great…

Effect That pH Has on It Abstract - The purpose of this experiment was to determine what variables affect the rate of photosynthesis. The variable tested was the pH level of the “environment” and this was tested using leaf discs from a plant. By testing the leaf discs in different pH levels of two, four, six, eight, and ten, it was found that the rate of photosynthesis was at its highest in a pH of six. It was also found that the rate of photosynthesis was at its second highest at a pH of…

Number: V00827823 The effect of different pH and temperature levels on the activity and action of catechol oxidase used from a solanum tuberosum specimen Abstract The various effects of temperature and pH on the enzyme activity and action of catechol oxidase, an enzyme containing copper which oxidizes phenols such as catechol with the use of dioxygen, were examined throughout several trial procedures. The experiment was conducted to determine the optimal pH for an enzyme to carry out its…

Discussion The research question of this paper asks: How is the pH of one’s mouth after a constant meal affected by the different sugar levels of various chewing gums. The chosen hypothesis was wrong for both the minty and sweet gums as it stated that their pH would be ultimately be acidic and there’d be a reduction form the initial pH. However, only one chewing gum had a significant decrease in its pH; the other pH values increased and either became alkaline or less acidic. There were several…

study 1 The acid base balance of the body is mainly regulated by respiratory and renal system together with the body ‘buffer system. For the body to function normally, the hydrogen ion (H+) needs to be concentrated within a narrow range, represented as pH, which determines the acidity and alkalinity of a solution. Changes in the bicarbonate (HCO3) concentration causes metabolic acidosis or metabolic alkalosis while changes in the rate of alveolar ventilation and carbon dioxide concentration…
