ADVERSE EFFECTS OF PEOPLE ACTIVITIES The Greenhouse Effect Too much carbon dioxide and other gases emitted by factories are accumulating in the atmosphere. These gases allow sunlight to penetrate the earth’s atmosphere but unfortunately‚ they also trap radiant heat and revert its escape into outer space. The immediate consequence is Global Warming‚ which is better known as the Green House Effect The rise in the average temperature of the earth could have serious consequence. Among them is

Investigating the effect of changing substrate concentration on the activity of the enzyme catalase The aim of this experiment is to examine how the concentration of a substrate (hydrogen peroxide) affects the rate of reaction of an enzyme catalyse (found in liver cells) Research Question: how does changing the concentration of the substrate affect the rate of reaction of the enzyme catalyse? Hypothesis: As the concentration of the substrate increases‚ so does the rate of reaction until the reaction

Liver and colon cleanse The colon and liver are very important organs in the body’s health with each having a specific task within the body when it comes to body detoxification. The colon is vital in eliminating wastes and water from the body‚ and the liver is responsible for filtering toxic substances and additives from the body. If both the two organs does not work correctly‚ waste full of dangerous substances and toxins can back up inside our body. This waste when left in our body can lead to

Enzyme Reaction to Variable Elizabeth Alvidrez University of Texas at El Paso Abstract: An enzyme is a protein that serves as a biological catalyst (Denniston‚ 2007). Metabolic reactions happen with in cells. Enzymes are proteins that are used to speed up these reactions without being consumed by them (Mader‚ 2010). Catalase is a catalyst that digests potent hydrogen peroxide and converts it into H2O and O (Campbell Reese‚ 2008). The environment plays an important role

Enzyme Report Case 1 - Hereditary Fructose Intolerance 1 & 2. Enzymes take on a variety of roles in the human body at the cellular level. Specifically‚ they aid in the breakdown of macronutrients such as glucose and fructose so that the body can use them. Although reactions within the body would occur without enzymes‚ enzymes provide control because the reaction is not needed all of the time. Enzymes function in specific environments such as temperature or pH; some enzymes are specific

Lab 6: Enzymes . header Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Time need to perform this lab: approximately 3 hours Preparation FIRST: Read the lab in its entirety TWICE before you begin. You will perform the experiment‚ write your lab report and include the answers to the additional 4 questions within the text for full credit on this experiment. Materials: •3% hydrogen peroxide •a household

The Liver is the body’s largest gland‚ weighing about three to four pounds. It is located beneath the diaphragm in the right upper quadrant (RUQ) of the abdominal cavity. Without the liver‚ our bodies would be poisoned and unfit for us to do anything at all. It is a metabolically active organ responsible for many vital life functions. The primary functions of the liver are: Bile productions and excretion. Excretion of bilirubin‚ cholesterol‚ hormones‚ and drugs. Metabolism of fats‚ proteins

Matthew Buckman Carla Baku English 1A 10:45 September 23‚ 2012 Beef Grass Fed Beef vs. Grain Fed Beef Before World War Two (WW2)‚ ranchers raised grass fed cows and that was the norm. But because of the high demand for beef after WW2 ranchers had to change the way they raised cows. Ever since WW2‚ cows have been raised on grain which has become the norm when it comes to raising cows. That means they are fed mainly corn instead of grass. With the cows being fed corn they get fatter quicker

Enzymes An enzyme is a protein used to speed up the rate of a chemical reaction. Because they regulate the rate of chemical reactions‚ they are also called catalysts. There are many‚ many different types of enzymes‚ because for each chemical reaction that occurs‚ an enzyme specific to that reaction must be made. To act on a substrate‚ an enzyme must contain an active site. The active site is the area on the enzyme that allows the substrate and enzyme to fit together. The amino acids that are present
