Objective: To investigate how pH affects the rate of protein digestion Hypothesis: I predict that since pepsin breaks down the material the quickest at a pH of 2 in the stomach‚ test tubes #3 will reduce the greatest because it has pepsin to further break down the egg. Whereas the other test tubes will have a smaller reduction. I think test tube #2 will have the second largest reduction rate and then #6 because they all will have a greater rate at breaking down the material‚ Then‚ I predict the

Correlation between the chemical activity of Amylase and change in temperature ABSTRACT This experiment focuses on how the change of temperature affects the rate of reaction of amylase. In the experiment there were four different environments that each contained 2 test tubes. Each test tube consisted of the same concentration and amount of starch and amylase. After having each test tube placed in these environments for several minutes a droplets of each mixture was placed onto each slot which

The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

The effect of Lead ions on amylase activity Aim What is the effect of Lead ions on the enzyme Amylase. And does it have an inhibitory effect‚ which causes the substrate‚ in this case starch to be blocked from the reaction process in the enzyme catalyst. Also is the effect reversible or irreversible‚ which is put on the amylase. Method Apparatus and substances required Test tube holder 2% starch solution 6 boiling tubes labelled 1 to 6 1% lead nitrate solution 6 test tubes labelled A to E‚

BIO 219 Group 1 Section 66 October 19‚ 2012 The extraction of purified DNA from A. fischeri by restriction digestion using Sal I enzyme and pGEM for shotgun cloning Introduction: The ultimate goal of this experiment is to isolate the lux operon‚ a targeted piece of DNA that causes bioluminescence‚ from Aliivibrio fischeri and insert it into the DNA of Escherichia coli in order to make it glow. A. fischeri is a gram-negative bacteria which participates in a symbiotic relationship with

One example would be the “Biodegradable plastic bags” made from the starch of the Cassava plant (Manihot esculent). The new plastic has been able to capture the interests of buyers‚ enabling it to advocate the benefits and obvious effects one can receive from using an eco friendly product.

Human Digestion Summary Nicole Koch SCI/241 August 1‚ 2012 Bruce Elliott Human Digestion Summary The digestive system provides two main functions‚ absorption and digestion. The main part of the digestive system is the gastrointestinal tract also referred to as the GI tract. This runs all the way from the mouth to the anus‚ about thirty feet long. The GI tract is made up of the mouth‚ pharynx‚ esophagus‚ stomach‚ small intestine‚ large intestine and anus. The transit time is the amount
