Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. Enzymes are catalyst for biochemical reactions; Enzymes lower the activation ATP so a reaction can begin over the energy barriers. In this lab‚ a discussion of the enzymes reaction to heat will be addressed. Does heat speed up the enzyme reaction? The prediction is as more heat is applied more reactions will occur then at some point the heat will denature the enzyme as it reaches

Biology 101 Exercise 2 Write Up A local chicken farmer heard a lot about the bird flu so he freely decided to apply monthly physicals for his chickens. An observation made is that chickens have a body temperature of 104 degrees Fahrenheit. That worries the farmer so he decides to conduct an experiment to try to figure it out. The question is “Do the chickens have a fever?” According to the information the cells are composed of hundreds types of enzymes and each one has a specific role in

temperature revealed that temperature of the surrounding environment had a significant impact on the alertness of the Daphnia. The control group for this study was the Daphnia placed at room temperature i.e. 22° Celsius. The experimental groups were the ones placed at 5° and 28° Celsius. The constant variables were food

back‚ meaning that the beaker was absorbing heat and letting close to none of it escape. The beaker that didn’t contain carbon dioxide only heated up around one degree celsius‚ from 22.4 degrees celsius to 23.6 degrees celsius‚ while the beaker that contained carbon dioxide heated up from 23.3 degrees celsius to 26 degrees celsius. The beaker without carbon dioxide didn’t get hotter because while it absorbed just as much heat‚ that heat was able to escape because there was not as much gas repelling

Looking through the data‚ we found that the freezing point of tert-butanol is 22 degrees Celsius. Besides finding the freezing point‚ we also need to calculate the molarity and molality of the additive substances in tert-butanol for our trials 2 and 3. For trial 2‚ the molecular weight of benzoic acid (C7H6O2) was found to be 0.25 grams. In

but it is solid. The inner core is about 4/5 as big as Earth’s moon. It is estimated that the temperature in the deep interior is in fact thought to be about 5400 degrees Fahrenheit (3000 degrees Celsius) at the core-mantle boundary‚ and at the center perhaps 7300 degrees Fahrenheit (4000 degrees Celsius). Beneath the crust‚ extending down about 1800 miles is a thick layer called the mantle Earth’s crust floats on the mantle much as a board floats in water. The mantle makes up 83% of Earth’s volume

feel hot. Methods/Materials I did three experiments. I mixed lemon juice and baking soda‚ammonia and vinegar‚ and finally‚ hydrochloric acid and sodium hydroxide. I did each experiment when the acid was 0‚ 20‚ 40‚ 60‚ and 80;all in degrees Celsius. Therefore‚ I could compare the exothermic reaction with the endothermic reaction at each temperature. For the Lemon Juice + Baking Soda experiment‚ I had a different set-up. On a beaker‚ which had baking soda in it‚ I put a stopper. The stopper

Experimental Analysis on Enzymatic Behavior of Human and Fungal Amylase Lab name and number: Enzymes‚ Lab #5 Panther I.D: 2640403 Shayra Medal Instructor: Emily Nodine Section U21 October 26‚ 2011 X_______________________ Abstract Section The concept of this experiment was to analyze the enzyme Amylase and its environmental behavior. Amylase breaks down the biological macromolecule‚ carbohydrates‚ specifically starch into condensed subunits categorized as monosaccharaides or disaccharides

The density of the inner core is 12.6-13.5g/cm2 and the temperature is 4300-7000 degrees Celsius. Rotating around the inner core‚ the outer core is liquid iron and nickel and is 2220 km thick.
