PH

Introduction This experiment looks at the effects of pH, enzyme concentration, and temperature of the catalytic rate of different enzymes including alkaline phosphatase (ALP). Some of the enzymes used are involved in human digestion while others are involved in clinical tests for certain diseases (Wilson, D’Alessio, Schmitt Lavin, Keith, & BIOL 1500 Team, 2015). The ALP enzyme is used to diagnose diseases such as bone cancer, jaundice and cirrhosis of the liver. This enzyme also catalyzes the…

This lab experiment was completed to determine the environment in which microbes prefer to live. The pH, moisture, available nutrients, oxygen and light all affect the rate in which bacteria grow. The majority of bacteria flourish when the pH level is near neutral; the growth rate is highly affected if the pH is off by just a little. If too acidic, the amount of time it takes the bacteria to adjust to a new environment (lag time) is increased which slows the growth, the activity of enzymes is…

The Origin Problem Since the time of Darwin, naturalists have attempted to explain how life formed through purely natural causes. Some naturalist models argued that either DNA or a protein provided the first possibility for life. However, problems with these models became evident as the researcher’s knowledge of DNA grew. The researchers discovered DNA relies on proteins for transcription and translation, but functional proteins cannot form without the information stored in DNA. The solution…

industrial revolution our climate has changed drastically. Industrial waste is now a necessary problem that collides with our daily life. This lifestyle can be too much for the fragile ecosystems our world holds. The rise of ocean acidification lowers the Ph level, which kills the coral that holds some of the most beautiful life. The Scientist who researched Ocean Acidification left a great understanding to how carbon works with the sea. These studies…

Different pH Solutions on Lactase. Caitlin Hathaway, 2016, Functional Biology, Texas State University, San Marcos, TX, 78666. Enzymes work at different rates in different environments. We investigated the relationship between pH levels and the ability for the lactase enzyme to catalyze reactions. Lactase was added to different levels of pH with substrate and their subsequent rates of catalysis were measured. Out of the four samples, the experiment showed that the lactase was most efficient in…

The Effect of pH levels on the Motility of Daphnia in Lake Ecosystems Introduction: The production, transportation, and use of chemicals by chemical industries can result in chemical pollution. This leads to a harmful effect on ecosystems and their balance of life (Linlin, Chen, 2012). The pH levels of aquatic environments are important because it affects the physiology of animals by changing their behaviors. The ion concentrations associated with the water and the organism’s survival can also…

As the pH level moves away from the normal balance of 7.0, it can negatively impact the survival and hatching rate of aquatic life.Both plastic and the fumes admitted when plastics are made, put excessive amounts of carbon dioxide into the ocean. This has caused the PH levels in the ocean to rise from a balanced PH level of 7, and has brought it up to 8.2. The jump in the acidity levels is destroying the great barrier reef, and shellfish beds. A raised PH level also poses a threat…

Most aquarists that have an irregular pH would rather use a natural means of balancing the pH of salt water because of the beneficial effects on, not only the overall water chemistry, but the non-lethal effects on the waters inhabitants. A very common pH balancer is crushed coral, which is a chemical mixture of solid aragonite. Aragonite is a polymorph of calcium carbonate, and a natural pH buffer. Crushed coral could quite possibly be the solution for reversing…

factors include variations of pH levels, temperature, and the presence of inhibitors. These factors can be detrimental to an enzyme and cause it to become denatured.…

It the coral, shell forming organisms and some phytoplankton in these ecosystems that are of the most concern with rising CO2 levels due the calcium carbonate that forms their exoskeletons and shells. The acidification of the ocean creates inadequate pH levels for the marine ecosystems. It is the coral polyps that are of the highest degree of interest as to their reactions to the acidification of the ocean due to rising CO2 levels, this essay will discuss the effects on individual corals, coral…
