pH Level Essay

Conclusion and Evaluation In this experiment, the effect of various pH conditions on catalase enzyme activity was observed. For the enzyme-substrate complex of this experiment, hydrogen peroxide, H2O2, is the substrate and the enzyme is catalase, which is secreted by yeast. 3mL of a pH buffer, available in pH 4, 7 and 10, was added to an equal amount of 3% hydrogen peroxide, H2O2. Then, to each of these three solutions, three drops of yeast that has been activated with warm water was added to catalyze

The Effect of 5 Drops of 0.1M Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) on The pH Level of 5mL of Tap Water, Distilled Water, Commercial Buffer, and 10% Homogenized Potato Solution Aya Ali Ms. Kim February, 29. 2016 SBI4U-04 Background / Pre-lab Questions: Figure 1: Logarithmic pH scale (WHOI, 2016) Almost all liquids that an individual encounters in their daily lives are classified as an acid or base, based on their hydrogen ion concentration relative to pure

Ocean acidification, the process by which the pH of seawater decreases which if it decreases far enough can potentially negatively affect a number of ocean based species. The effects have been studies across a number of species and at least for the Mytilus edulis or blue mussel species, Fitzer et al. discovered that the an increase pH led to the Mytilus edulis developing rounder and thinner shells thus making them more likely to experience cracks and breaking in their shells from all sorts of natural

The normal pH value for the body fluids is between pH 7.35 and 7.45. When the pH value of body fluids is below 7.35, the condition is called acidosis, and when the pH is above 7.45, it is called alkalosis. (Tortora, G., Derrickson, B., 2014) The major effect of acidosis is depression of the central nervous system. When the pH of the blood falls below 7.35, the central nervous system malfunctions, and the individual becomes disoriented and possibly comatose as the condition worsens. Causes for acidosis

students to observe the effects of pH and enzyme concentration on catecholase activity. Enzymes are organic catalysts that can affect the rate of a chemical reaction depending on the pH level and the concentration of the enzyme. As pH comes closer to a neutral pH the enzyme is at its greatest effectiveness. Also at the absorbance of a slope of 0.0122 the enzyme is affected greatly. The pH effect on enzymes can be tested by trying each pH level with a pH buffer of the same pH as labeled as the test tube

Acid Rain: its Effect Acid rain refers to precipitation that is more acidic (having lower pH levels) than average. In more detail, acid rain is a type of precipitation that has mixtures of wet and dry materials coming from the atmosphere, which includes more nitric and sulfuric acids (Conserve Energy Future: Acid Rain). Acid rain can also be written as “Acid Deposition” because the acid rain could come down as other precipitation, for instance, snow. This became a worldwide problem due to the

A person’s normal pH range is between 7.35 and 7.45. (Tortora, G., Derrickson, B. H. ,2014-01-22). This range is important for the body to function properly. There certain conditions that can cause the pH range to fluctuate. Acidosis is a condition in which the blood pH is below 7.35 and alkalosis is a condition in which the blood pH is higher than 7.45. Significant changes in pH range can affect cellular function and possibly lead to death. “Your blood needs the right balance of acid and basic

David Shabazi Professor Loza-Coll BIOL107 11/17/15 Mini Research Proposal Background: Every ecological system provides multiple services for the organisms that live in that specific ecosystem. Some more than others, depending on the biome and health of the environment. One of its roles serve to act as a resource base, available to all nearby organisms for survival purposes. This "resource base" is finite, however. When not used wisely, resources will most often deplete dangerously quickly, resulting

The objective of this lab was to examine the effect of an environmental variable on the catalytic function of an enzyme. To the point, the objective was to perform an experiment to test the effect of pH on the function of the enzyme amylase. Enzymes are proteins that are catalysts for reactions. This means that enzymes lower the energy required for a reaction to take place. Thus, permitting a reaction to take place more easily. Some enzymes are shape specific and lower the energy for certain

7:50 Lab 1 February 2, 2015 pH and Buffer – Using Red Cabbage Indicator to Measure pH Introduction This experiment was performed to evaluate the following hypothesis: Red cabbage indicator can be used as a measure of pH. According to Campbell, et al, in Biology: Concepts and Connections, red cabbage contains a water-soluble pigment called anthocyanin that changes color when it is mixed with an acid or a base. The pigment turns red in acidic environments with a pH less than 7 and the pigment
