pH Level Essay

Homeostasis of the pH levels in the body is very important to the overall survival rate of human. Secondary to the brain and heart, the arterial blood pH is one of the most critical levels that must be maintained in order to avoid serious complications including death. Four conditions that can be associated with an abnormal arterial blood pH level are respiratory acidosis, respiratory alkalosis, metabolic acidosis, and metabolic alkalosis. The body has natural compensatory mechanisms in place to

What is pH? PH (Power of Hydrogen) is the measure of acidity or basicity of any aqueous solution. The power of hydrogen just means that you are measuring the concentration of the hydrogen ion in a solution. A sample of 100% pure water has a pH level of 7.0 meaning that it is neutral. It is considered neutral because of the way the pH scale is set up. The way to measure the pH level of a solution is by using the pH scale. The pH scale consists of numbers from 0-14. What does these numbers mean? Any

This experiment is being performed to show the effect of pH levels on daphnia by changing pH levels and measuring the heart rate. Introduction Daphnia are used to test water toxicity, they are a vital part of fresh water ecosystems. They are a food source for smaller fish and invertebrates and considered to be a consumer of algae and bacteria (Elbert, 2005). These small crustaceans range in size from 2-5mm long and are commonly referred to as water fleas. Daphnia belong to the group called Daphniidae

configuration of an enzyme would stir the catalytic activities, factors including pH and temperature influence this and result in browning, a chemical change. Enzyme are known to act rapidly, therefore if it placed in a high temperature this would begin the breaking down and denature process which present less reaction. On the other hand if temperature is drop to freezing levels the enzyme would slow down or cease. A change in pH levels cause the enzyme to adapt to the various ranges however it will denature

Ankita Batra Section 13156 The Effect of pH Level on Starch Digestion by the Activity of Amylase and the Examination of the Rate of Starch Disappearance Using Iodine Solution Introduction A key enzyme found in the saliva of humans, alpha-amylase, is involved in the early stages of starch digestion. This type of amylase is classified by its glycosidic bonds and is mainly found in the bodies of animals. The digestion of starch will begin with the enzyme in saliva and will continue to break down starch

activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic, the catecholase was less

Joshua Kwon Sep 19, 15 Biology p 4 How Do Changes in Temperature and pH Levels Affect Enzyme Activity? Lab Report In biology class, we’ve learned that sugars produce energy and to use sugars to gain energy, an organism needs a proper enzyme should exist to break it down the chemical bonds of the sugar. Enzymes and proteins are important in organisms because they are involved in most chemical reactions that take place inside of an organism. Our example of an important enzyme was catalase

The relatively close pH levels of Tap Water, Spring Water, Flavored Water, and Seltzer Water. Introduction This experiment was performed to investigate the following hypothesis: The following four different types of drinking water (spring water, seltzer water, tap water, and flavored water) we test will relatively have the same pH level. Our group decided to test different types of drinking water to see if a pH level of tap water is comparable to other types of water. Many people believe

of this project was to discover how the pH level affects corrosion rate. The hypothesis was if the pH level affects the corrosion rate, then the lower the pH level is quicker the corrosion rate would be. This will happen because liquids below the pH level of 7 possess stronger acidic attributes. The effect of pH level on corrosion rate was determined by depositing a copper penny in each of three plastic cups, and then three different liquids by their pH levels, were assigned to be displaced into each
