Effect of Temperature on Content of Vitamin C Introduction A daily intake of Vitamin C is essential for humans. Without it‚ the disease scurvy develops as sailors‚ explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C is found in high levels in foods such as oranges‚ limes‚ lemons‚ blackcurrants‚ parsley and capsicums. Vitamin C is water

Abstract: This project looks at how the temperature of an experiment can affect its reaction time. The purpose of this experiment is to determine if dissolving reactions are affected by waters temperature. I believe that if the H2O temperature increases‚ then the Alka-Seltzer tablet will dissolve faster because the hot water molecules will move faster colliding with the tablet particles. Water will be the independent variable due to the fact is will always stay in its same form throughout the

Average Age of First-time Homeowners Sujei A. Rodriguez Introduction to Logic Research Assignment The U.S. homeownership rate fell to the lowest level in 15 years in the first quarter of 2012‚ as borrowers lost homes to foreclosure and tighter inventory and credit kept buyers off the market. (Gittelsohn‚ 2012). The Census Bureau reported a rate dropped to 65.4 percent from 66 percent in the fourth quarter of 2011. According to the Census Bureau in June 2004 there was a record

For me‚ I was just being the average Joe. I never noticed anything different from my world to the next‚ I never noticed the degree of my living compared to anyone else’s. I just knew my life was the life I lived. The average Joe life was me pretending the hole in my floor were merely quicksand that I had to be light on my feet to dodge. The ramen noodles we had for dinner were more just a filler‚ it was a five-star dish. The broken A/C was an adventure to the Sahara Desert and the old used cars

Hypothesis The optimum temperatures of Alcalase and Savinase will be different. Above and below their optimum temperatures activity will decrease. Biological explanation This investigation is designed to look at the effect of temperature on the activity of the proteases Alcalase and Savinase. By the end of it I hope to know the optimum temperature of both proteases. The substrate I am going to use during the experiments is the protein gelatin‚ which is a translucent‚ colourless‚ brittle solid

INVESTIGATING THE EFFECT OF TEMPERATURE ON THE RATE OF ENZYME ACTIVITY. To investigate the effect that temperature has on enzyme activity I am going to use the enzyme amylase‚ which is used as a biological catalyst to break down starch‚ which cannot pass through the gut wall due to the size of the molecules‚ into smaller ones. Amylase is a carbohydrase‚ which converts starch to simple sugars in the Salivary Glands. Three features of all enzymes are: They are always proteins. They are specific

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is
