the optimum pH for catalase in potatoes. This is because the height of the bubbles was the highest of all three tests (pH 3‚ pH 7‚ pH 9) reaching an average height of 0.433 cm. See graph 3. While pH buffer 3’s average height was 0.233 cm only reaching a maximum height of 0.3 cm in Trial 3 and pH buffer 9’s average height being 0.333 cm only reaching a maximum height of 0.4 cm again in Trial 3. See table 1. Therefore this supports my hypothesis: At pH buffer 7 the enzyme (catalase) will work most efficiently

They maintain the body’s stable internal balance‚ and without them life would

Purpose Understanding how catalase activity is affected by pH is the purpose of this experiment. Introduction Enzymes play an important role in daily life because of the chemical reactions. Almost chemical reactions require the presence of enzymes to promote the metabolic process. They are known as the incredibly efficient and highly specific biological catalysts. Most enzymes are protein with the ability to enhance the rate of reaction between molecules. To catalyze a reaction‚ the enzymes

quickly. However‚ there is a reason. The Cold War triggered an explosion of growth and interconnectivity. And it came close to triggering several other literal explosions. Global economy changed abundantly because of the cold war. Fighting broke out in many developing countries‚ stunting the growth of their economy‚ and widening the gap between the poor and rich. Other developed countries spent exorbitant amounts of money stockpiling weapons. Although the cold war did not have all good effects

Whether they be for independence from colonialism or for a new change‚ we have seen how those developing nations have constantly been transforming themselves into the nations we now know them by in today’s world. Moreover‚ we see the superpowers they

Caffeine stimulates receptors located in cells within your heart to increase your heart rate. Effects of this stimulation speed up your blood flow because of an increase in heart rate‚ as well as an increase in blood sugar‚ urine production and body temperature. Function Physiologically‚ caffeine stimulates the receptors within your heart to beat faster by blocking the enzyme phosphodiesterace. Phosphodiesterace works together with another enzyme‚ cyclic AMP‚ to keep your heart rate at its normal range

The Cold War is considered to be a significant event in Modern World History. The Cold War dominated a rather long time period: between 1945‚ or the end of the World War II‚ and 1990‚ the collapse of the USSR. This period involved the relationships between two superpowers: the United States and the USSR. The Cold War began in Eastern Europe and Germany‚ according to the researchers of the Institute of Contemporary British History (Warner 15). Researchers state that “the USSR and the United States

Effects of the Cold War on Canada The distrust between the Western World and Communists‚ as well as the conditions after WWII caused the Cold War to begin. From 1946 to 1991 a mass arms race rose and Canada was stuck in between the grudge of capitalism and communism. The Cold War affected Canada through Canadian citizens fear of being nuked‚ sexism against women and the unfair treatment towards communists & socialists. With Canada’s ally the United States partaking in the Cold War with the Soviet

The complex dynamic between the Soviet Union and the United States of America was not ever present‚ but evolved out of a series of key disagreements during World War II. With the onset of Operation Barbarossa‚ Nazi Germany shifted emphasis from an already dominated Western Europe to its eastern border with Russia. The betrayal of the Nazi-Soviet non aggression pact came as a surprise to Stalin‚ who quickly began mobilizing fighting aged men to bolster his vulnerable ground defenses. The resulting

different regions in a positive and negative way. The geographic features always impact the region‚ For example monsoons‚ desserts‚ and cold climates can affect a region in different ways. It can change the way people in that region live. It could differentiate what they eat and the climate so how they dress. The geography is a very big impact when dealing with how to live in regards to geography. In particular deserts and monsoons have had a variety of impacts on different regions around the world
