Restriction enzyme

(ACS, 2016). What is a specific example that exists for pharmaceutical reactions? A specific example that exist for a pharmaceutical reaction may consist of a transfer of an acetyl group from an aspirin molecule to a serine amino acid of a protein enzyme known as a COX inhibitor. An example of a balanced chemical equation would be aspirin+COX→salicylic acid+COX-OAc (Ilocis, 2016). What is the difference between diagnostic chemical reactions in healthcare? A diagnostic chemical reaction…

The hypothesis that rate of respiration of chickpeas is highest at room temperature is not supported by the data, although there was error in the data. The data from the lab showed rate of oxygen consumed to be the highest at 1.5 degrees Celsius with a rate of .0124ppt/min/g. At room temperature there was a rate of .0077ppt/min/g, and at the hottest temperature (95.6 degrees Celsius) a rate of -.0131ppt/min/g, meaning that oxygen was not consumed but actually increased in concentration in the…

The data in Figure 1 supported both our hypothesis and our predictions. The solute concentrations affected our model organism the Gallus gallus domesticus. The weight of the G. gallus domesticus egg has a greater decrease in mass when added to a higher concentrated solution than a lower concentrated solution. The data also supported the prediction that the mass of the G. gallus domesticus egg in 10% NaCl will weigh less than the G. gallus domesticus egg in the 1% solution. Diffusion and osmosis…

Enzymes are protein molecules that occur in all living things on earth and enable chemical reactions. Enzymes not only provide an alternate pathway for a chemical reaction, with a lower activation energy, they also bring substrates together in an optimal orientation, thereby speeding up the rate of reaction (Slide Share 2016). In an enzyme catalyzed reaction, the substrate (reactant) binds to the active site and forms and intermediate substance known as the enzyme-substrate complex with the…

1. The color of Max’s urine tells Tracy what the concentration is because the darker the urine color, the more concentrated it is. The clearer it is, the less concentrated it is. Urine pigment correlates with specific gravity because the more concentrated (darker) a urine sample is, the higher the specific gravity will be as well. 2. Based on the urine color and specific gravity, Tracey is able to conclude Max’s hydration status during the different recorded stages. Before he exercises, Max’s…

Homeostasis is a controlled state in which the body is able to function optimally. An equilibrium of the body’s physiological mechanisms are maintained and kept under control, if the equilibrium is lost it can be fatal for an individual. (Waugh, Grant, 2014) In order to maintain a balanced internal environment the body is required to adjust when needed to, this is known as homeostatic regulation. A cluster of cells with the hypothalamus is known as the control centre; this sets the limits at…

To determine the effect of the proximity of the dam on fish distributions downstream, I will collect data at three locations along the Monongahela River, moving downstream from the dam (Site 1, Site 2, and Site 3 in Figure 1.A). I will repeat this two times on two different days of similar weather patterns for a total of $110 in anticipated costs. At each site, I will collect a variety of variables. For starters, I will collect an indication of water clarity using a secchi disk at each site for…

Purpose This lab’s purpose was to experiment how much of a syrup solution would seep through a dialysis bag at different temperatures. Procedure We prepared by filling up three dialysis bags with about 100 mL of a syrup solution. We tied knots on either end and measured the initial mass of the bags. The bags were measured in grams. Then we added water to three different beakers, each being a different temperature. One beaker was room temperature, another was heated to about body temperature…

Fig. 1. Various nuclear changes of erythrocyte in the blood smears of fish treated with sub-lethal concentrations of profenofos such as (a) control (regular cell), (b) micronucleus, (c) bi-nucleus, (d) degenerated nucleus, (e) notched nucleus, (f) nuclear bridge, and (g) nuclear bud. Two groups of fish were exposed to 10% and 50% of LC50 of profenofos for 7, 15, and 30 days, while third group treated as control (0% profenofos). Three slides were prepared for each fish and 2000 cells were scored…

In non-competitive allosteric inhibition, inhibitor molecules bind to an enzyme at the allosteric site. Their binding induces a conformational change that reduces the affinity of the enzyme's active site for its substrate. The binding of this allosteric inhibitor changes the conformation of the enzyme and its active site, so the substrate is not able to bind. This prevents the enzyme from lowering the activation energy of the reaction, and the reaction rate is reduced. However, allosteric…
