Geoffrey Zhang: The Science Of Home Alone

• Fourthly, we kept the temperature at a constant 25°C using a water bath. At low temperatures, an increase in temperature causes an exponential increase in enzyme activity. This is because an increase in temperature provides more kinetic energy for the collisions of enzymes and substrates, so

Most chemical reactions speed up as temperature is raised. As the temperature is raised, kinetic energy within the molecules increases as well to endure the reaction. Because enzymes are catalysts, meaning they make a chemical reaction react faster, enzyme reactions also tend to go faster with increase temperature. However, if the temperature of an enzyme-catalyze is raised to a temperature optimum, the kinetic energy in the water molecules and the enzyme becomes too high and the enzyme starts to denature, meaning the molecules become disputed. Most enzymes are denatured by around 104 degrees Fahrenheit to about 122 degrees Fahrenheit. Denaturing is disabling an enzyme by changing the normal qualities or the nature of it, for instance when

The temperature can have a major impact on an enzyme. According to Campbell Biology author Reece etc. 2011 “The enzyme reaction will increase as the temperature increase with the increasing temperature….substrates collide with active sites more frequently when the molecules move rapidly.”(Reece etc 2011) Every enzyme hits its optimal temperature the reaction will be at its highest point.(Reece etc. 2011) When the

Temperature controls the speed the enzymes work at. Higher temperatures increase the kinetic energy which increases the chance of collision therefore speeding up the rate of

These results show how temperature of extreme high, or low affects enzyme activity. The highest rate of enzyme activity occurred at 37 Cº. Anything that was hotter or cold than 37 Cº slowed the reaction rate. As I thought, 100 degrees would denature the enzyme, and that was the case. The data provided shows exactly what temperatures enzymes work best, and worst. The objective was achieved as we discovered the different reaction rates under different temperatures. The results are reliable, as we know enzymes do not work well when under extreme heat or denaturation occurs. What I learned in this experiment was that enzymes don’t work well under cold temperatures because they tend to move slower. My hypothesis did not quite match, because I thought they work best at lower temperatures.

Most enzymes work best at body temperature, higher temps will cause the enzyme to no longer work properly

If temperature of the water(enzyme environment) is increased to 35°C, then the enzyme activity will

Enzymes will denature if they get too hot or cold or if the pH of the solution they are in is too high or too

The optimal temperature permits the utmost number of molecular collisions and the fastest alteration of the reactants to product molecules. Most human enzymes have an optimal temperature of about 35-40°C (close to body temperature 37°C).

Decreased blood flow can result in organ failure. Increased heart rate is a sign of shock related to severe burns. Anion gap may result from acid-base imbalance. Finally, electrolyte imbalance may lead to alterations in cellular functions. Cardiac arrhythmias are another clinical manifestation of severe burns.

When I arrived DD was home and her behavioral specilist was at the house. DD started cooking dinner. DD cooked hamburger helper, peas, carrots, and corn. DD's roommate did not eat, DD was upset when only herself and one other roommate ate. DD became vocal about how no one wanted to eat her food and how she worked hard to cook the food. DD and I went to dollar tree and to her coach's house. While in the coach's house I asked DD for her coach's number and DD did not know or have his number on her. When we arrived DD would not go knock on the to the door. After I told her to go knock on the door. Finally the coach came out. DD barely spoke to him. DD and I went with her roommates in the Wintergreen house. While at the wintergreen house DD spoke

-Plaintiffs' expert, a scholar in thermodynamics applied to human skin burns, testified that liquids, at 180 degrees, will cause a full thickness burn to human skin in two to seven seconds.

. Various biological and metabolic changes occurs as a result of burn injury including degradation of adenosine triphosphate and considerable reduction in polyunsaturated fatty acids in red cell membrane(Nagane, Ganu et al. 2004). Although many treatments have been discovered, Healing of wound still remains a challenge to modern medicine.

Any ignition source such as an open flame, cigarette or electric spark could potentially ignite this flammable atmosphere to the point of flash fire or explosion.

Thermoregulation is important, especially in humans, as temperatures above 40 degrees Celsius cause enzymes to denature rapidly. Enzymes have an optimal range for catalysing reactions. Temperatures below this cause for the rate at which reactions occur to decrease, whereas temperatures above this can lead to the denaturing of enzymes and important metabolic reactions unable to occur. Therefore it is essential for enzymes in the body to be functioning.
