Nitrogen balance studies have been used to determine protein needs. Describe the different nitrogen balances and examples of who may be at those balances. a. Equilibrium b. Negative c. Positive 12. a) What is deamination? b) How does the body handle the ammonia that results from that process?
(PubmedHealth, 2009) Fructose 1 phosphate which is the substrate of Aldolase B is split by Aldolase. This splitting is done by the lock and key design because the fructose 1 phosphate fits into the aldolase. The lock and key model enables the molecules called substrates to go through chemical changes to form new substances called products. Substrates are what enzymes act upon. Each substrate fits into an area of the enzyme and is called active sites.
(ABSORBANCE vs. TIME) The graph shows that the enzyme works at ph5. Figure 3b shows data on REACTION RATE vs. the effects of pH on peroxidase activity. The graph shows that the enzyme works at ph5 Figure 4a shows the slope of each plot, which represents the enzyme reaction rate for the effects of enzyme inhibition experiment. (ABSORBANCE vs. TIME) The enzyme did not work with the inhibitor. Figure 4a shows data on REACTION RATE vs. the effects of enzyme inhibition experiment.
Review the effect of pH on enzyme function. Students should understand that enzymes function best at specific pH levels (which vary depending on the enzyme). Non-optimal pH levels can affect the shape of the enzyme, thereby decreasing its effectiveness as a catalyst. Extreme pH levels can permanently denature the enzyme protein, whereas less extreme pH conditions may only temporarily alter . Lactase is effective at pH 2 – 7 (including dH2O) and therefore breaks down the lactose sugar in milk into glucose and galactose.
Chemistry PAT Question 1 Polyhydroxybutyrate (PHB) is a biopolymer with properties very similar to that of polypropylene, though has all the benefits that come with biopolymers. PHB was first introduced to the scientific community by the scientist Maurice Lemoigne in 1926. He noticed that to produce PHB you need particular micro-organisms such as Alcaligenes Eutrophus or Bacilius megaterium undergoing physiological stress in an apparatus such as an agar dish to allow the micro-organisms to multiply. In order to achieve this stress there is a restriction to the amount of nitrogen the micro-organisms can attain thereby altering its nutrition. This is quite an efficient method of production and the amount of the PHB polymer yielded is around 30-80% of the dry weight of the micro-organisms used.
Controlled Variables. temperature; pH; sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. The amount of product produced is an indicator of sucrase activity. This is an indicatore because sucrase is an enzyme found in the small intestine that catalyzes the splitting of the disaccharide sucrose into the monosaccharides glucos and fructose.
Therefore the two kinds of fatty acids compete for same enzyme complex; however, monounsaturated fatty acids are formed in greater concentration than VLCSFA. The reduction in the elongation of VLCSFA and a diet low in VLCSFA will slow the demyelination
The rate of reaction is determined on a level of 0 to 4 which is slowest to fastest. Throughout the chemical reaction (the production on benzoquinone), there will be a series of color changes. At the very beginning the enzyme and substrate will be clear; as the benzoquinone is produced there will be a gradual change to a faint peach-ish color, then yellow to orange-ish red, and then on to its final stage at a dark brick reddish color (benzoquinone has now been produced). The time it takes for the enzyme to change to dark red is the rate of reaction. (2.)
3. First-pass elimination by the liver is reduced because of the immaturity of the liver and reduced levels of microsomal enzymes. 4. Intramuscular absorption
Enzymes are biological catalysts for all processes going on inside cells. 3. They are able to be used over and over again 4. They increase the rate of chemical reactions at lower temps and decrease the activation energy needed for metabolic
