The rate of reaction when Ph, temperature, time and the substrate are at a constant is determined by the enzyme availability. Effects of enzymes in substrate concentration can be analysed as below. The concentration of enzymes is a factor in determining the rate of reaction. The substrate needs to be present in excess. That is to say that each reaction should be independent of the concentration of the substrate. Any possible change in product amount over a given time period depends upon present enzyme level.
A and E reacting leads to B at a constant rate k1, this turns to C and generates E again at a constant rate k2. At that instance, B has the possibility of turning into A and E again at a constant rate k-1. Michaelis-Menten enzymatic catalysis mechanism follows this path.
Competitive inhibition has a molecule similar to the present or available substrate but not able to be acted on by those enzymes that compete with them for sites that are active. Fewer active sites readily act on the substrate because of the inhibitor presence. Given the structure of the enzyme is not affected by the enzyme inhibitors; they will still act as catalysts for the reaction.
In inhibition that is uncompetitive, molecules tend to bind to enzymes instead of sites that are active. That makes the three dimensional enzyme structures to change in that its site that is active still binds to the substrate in affinity that is usual, though not in the optimal arrangement of stabilizing the rate of transition and in turn catalyzing the reaction.

The Effects of Temp & PH on Enzymes

...units at 370C and it decreased to 0.06 units at 650C and further decreased to 0.05 at 1000C. Similarly, from table 2 on Class data of -amylase activity at different temperatures the activity of the was 0 at 40C, increased to 0.135 units at 230C and reached its peak of 0.34 units at 370C and decreased to 0.01 at 650C and further decreased to 0.045 units at 1000C. From the above results it is evident that the activity of -amylase is at its highest at body temperature of 370C, a confirmation that enzymes work optimally at this temperature. This is also shown by graph 1 above. Table 3 indicates that at lower pH values, enzyme reactions are lower rising towards neutral Ph and peaks at 7. This fact is illustrated by graph 2 above....

It also has traces of hydrated copper (II) sulphate and potassium sodium titrate. The blue color appears as a result of presence of proteins, pink and blue may also arise in the presence of short chained polypeptides. A biuret reagent is not required in all protein tests. It is commonly used in biuret protein assay. On the other hand, a colorimetric assay is used in the determination of protein concentration. . I deal examples entail UV-VIS wavelength of 540 nm in the detection of Cu2+ ion (Layne, 1957, 23). Conclusion Biuret reagent is one of the common reagents used protein tests. It is highly...

Enzymology

...Enzymology Enzymes are protein-based molecules that facilitate biochemical reactions. This paper investigates the factors affecting the catalase enzyme activity to the conclusion that temperature, pH, substrate concentration, and presence of enzyme inhibitors influence activity of the catalase enzyme. Introduction Enzymology is a branch of science that studies the nature and functionality of enzymes. Catalase enzymes are susceptible to the environmental factors such as temperature, substrate concentration, pH level, enzyme concentration, and presence of enzyme inhibitors (Stocker, 2010; Saini, 2010). Substrate concentration is directly proportional to activity rate up to a point beyond which the reaction...

..., and other germs, and also chemical composites. It is however important to elucidate the fact that in salmonella, TolC relies on other mechanisms for accountable for the removal of noxious substances from the cells. According to Horiyama, Yamagichi and Nishino (2010), these other mechanisms include "AcrAB, AcrD, AcrEF, MdtABC, MdsAB, EmrAB, and MdfA, MacAB, and MdtK" (p. 1372). In a nutshell, the function of the TolC gene in salmonella is aiding in the secretion of noxious substances from the cells of salmonella. References Horiyama, T., Yamaguchi, A. & Nishino, K. (2010).

Protein isolation

...Protein Purification Protein Purification Introduction Majority of scientific studies today require the isolation, purification and study of micro-molecules in biochemical processes. The existence of a myriad of protein isolation and purification techniques is a direct consequence of these scientific studies (Jordan and Ogren, 1981). Enzymes are among the most studied proteins due to their crucial role in regulating metabolic processes. Enzymology entails the use of isolation and purification techniques similar to those used in proteomics. Ribulose 1, 5-bisphosphate carboxylase/oxygenase (rubsico) is one of the most abundant proteins in the universe a reaction on the synthesis of sugar in green plants (Jordan and Ogren,...
