hypothesized that if the concentration increased‚ then the reaction rate would also increase. To test our question‚ we varied a combination of substrate and buffer‚ totaling 6mL‚ with a constant amount of 2 drops of catalyst. The enzyme catalyst‚ peroxidase‚ increased the rate of the reaction. The results of our experiment can be found by comparing the reaction rates for each trial. These rates are actually the slopes of the lines that were graphed during each reaction. The trend of data

Biochemical Pathways of Heavy Metals Poisoning BIO101 (Principles of Biology) 6 July 2012 Abstract The biochemical pathways of heavy metal poisoning are routes by which the metals pass in the body as they impair and destroy normal cellular and organ activity. The most common types of heavy metal poisoning are caused by lead‚ arsenic‚ cadmium and mercury. They are also the most extensively studied at the moment. Lead poisoning occurs mainly by the inhibitory effect that the metal imposes on enzymes

Introduction Over the course of several weeks‚ myself and my fellow classmates have been researching and conducting an experiment that focuses on the effect of ascorbate peroxidase (a.p) as well as salt stress at different levels of concentrations on Abelmoschus esculentus (okra). Okra is a plant that is composed of 87.1% of water. In addition to being made mostly of water this highly nutritious vegetable is also composed of 0.2% of fat‚ 9.7% of carbohydrate‚ 2.2 % protein‚ 1.0 % fiber‚ and 0

Then the spectrophotometer to 470nm and the first spectrophotometer tube was wiped to be used to blank the spectrophotometer. Then 0.1 mL of enzyme from vial E1 ( 1x10^-7 M peroxidase) was added‚ then it was shaken with parafilm covering the top. The tube was quickly placed into the spectrophotometer‚ and it was necessary to be sure not to spill any of the reaction mixture or this experiment would have to be repeated. The absorbance

150 times more resistant to fluoroacetate intoxication in vivo than the same species from South Australia. Both possums are capable of de-fluorinating fluoroacetate at similar rates by a glutathione-dependent enzymic mechanism resulting in the formation of free fluoride ion and S-carboxymethylcysteine. Glutathione was also capable of partial protection against the toxic effects of fluoroacetate in vitro by a further unelucidated mechanism. This tolerance appears to be an adaptation to the presence

REVIEW SHEET‚ EXAM 3 Chapter 6‚ Nutrition and Microbial Growth Define the four major modes of nutrition in microorganisms and distinguish among them in terms of energy and carbon sources The four major modes of nutrition are: 1. Photoautotrophs: (ex. Plants‚ some protozoa‚ & alegae) -microorganism which use carbon dioxide as a carbon source and light energy from the environment to make their own food. 2. Chemoautotrophs: -microorganism which uses carbon dioxide as a carbon source and

It’s a kind of good compound for human consumption and especially beneficial for those people who want to reduce aging (lightened the skin by affecting the skin
