Enzymes are types of proteins that work as a substance to help speed up a chemical reaction (Madar & Windelspecht, 104). There are three factors that help enzyme activity increase in speed. The three factors that speed up the activity of enzymes are concentration, an increase in temperature, and a preferred pH environment. Whether or not the reaction continues to move forward is not up to the enzyme, instead the reaction is dependent on a reaction’s free energy. These enzymatic reactions have reactants referred to as substrates. Enzymes do much more than create substrates; enzymes actually work with the substrate in a reaction (Madar &Windelspecht, 106). For reactions in a cell it is

Living cells within our bodies perform an abundance of chemical reactions very speedily because of the participation of enzymes. Enzymes are biological catalysts that speed up a chemical reaction without being depleted or altered in the reaction (Garrette & Grisham, 1999). The

The success of VIP University is dependent upon its students. It is important to recognize who the hard working students are and praise them. An absolute performance management system will help professors understand the abilities of a student for further growth and development. The professor can measure the grade of students and compare it with established targets and plans. The professors are in the position to guide the students toward performing better in the classroom. The main objective of an absolute performance management system is to identify the performance gap of the students. This gap is the shortcomings that result when performance does not met the standards set by the university. An absolute performance management system allows

Sentinel events are a subset of medical adverse events. Events that require immediate attention are called Sentinel Events. Joint Commission defines a sentinel event as an unexpected occurrence involving death or serious physical or psychological injury, or the risk thereof. Serious injury specifically includes loss of limb or function. The phrase “or the risk thereof” includes any process variation for which a recurrence would carry a significant chance of a serious adverse outcome. Sentinel Event identified by Joint Commission also include infant abduction or discharge to the wrong family.

Overbooking is a highly controversial issue that has been on the agenda for many years. It is not only a business topic but also an ethical matter. Overbooking can be examined through many ethical theories.

Escherichia coli, or E. coli, is a common bacterium that can be found in diverse environments all over the planet, including the gastrointestinal tracts of animals and humans. Many of these strains of E. Coli are essential mechanisms in the digestive tract, while others are pathogens that can cause complications in urinary and intestinal tracts. (Payne & Sparks) In research, E. Coli is commonly used as a model organism, meaning they are widely studied by scientists for a variety of purposes due to their experimental advantages. E. Coli is comparatively simple, and there are many advantages to studying these prokaryotic cells in the fields of biochemistry and molecular biology. E. Coli has this simplicity and is relatively easy to propagate in a lab environment. Their genome has been completely sequenced and many things we know about DNA, protein synthesis, and gene linkage have been derived from studies regarding this particular organism. (Cooper)

On January 24, 2016, a Hospital Services Dispatcher began the selection process for neonate red blood cells for Morristown Medical Center (MMC) located in Morristown, NJ. The Dispatcher selected the units but did not verify the CMV status of the tag against the CMV status on the ABO/Rh label. The units were brought to the Technical Services Laboratory for sickle cell testing. After testing was completed, the products were returned to the Dispatch area. An electronic shipment was created in the blood establishment computer system (BECS), and a packing slip was printed. The Dispatcher reviewed and signed the packing slip but failed to have the Lead Dispatcher or an available driver complete the secondary review. The order was shipped to MMC

The current level of office automation at NDAS varies with each department. The company is also in the process of upgrading its computer systems to improve performance and reduce costs.

On December 8, 2017, the Bi-State Regional Commission and QC public transit agencies, in partnership with the Iowa Department of Transportation launched a regional rideshare portal called QC Rideshare, as a sub-portal of the Iowa state rideshare site.

My results visibly show that the optimum for this enzyme is pH 7, the pH at which the highest rate of oxygen production was obtained, at 0.80 cm3 sec-1, corresponding to the highest peak in the graph. The other rate values obtained from more acidic pHs, for example at pH 2 and pH 4 were much less, measuring 0.02 cm3 sec-1, and 0.07 cm3 sec-1, respectively. This shows that a decrease in pH from the optimum decreases the rate of the reaction. Subsequently, an increase in alkalinity had a similar effect, a decrease in rate, at pH 10 and pH 12, yielded rate values of 0.08 cm3 sec-1, and 0.07 cm3 sec-1, respectively. This shows that an increase in pH from the optimum also decreases the rate of the reaction.

Organisms cannot depend solely on spontaneous reactions for the production of materials because they occur slowly and are not responsive to the organism's needs (Martineau, Dean, et al, Laboratory Manual, 43). In order to speed up the reaction process, cells use enzymes as biological catalysts. Enzymes are able to speed up the reaction through lowering activation energy. Additionally, enzymes facilitate reactions without being consumed (manual,43). Each enzyme acts on a specific molecule or set of molecules referred to as the enzyme's substrate and the results of this reaction are called products (manual 43). As a result, enzymes promote a reaction so that substrates are converted into products on a faster pace (manual 43). Most enzymes are proteins whose structure is determined by its sequence of its amino acids. Enzymes are designed to function the best under physiological conditions of PH and temperature. Any change of these variables that change the conformation of the enzyme will destroy or enhance enzyme activity(manual, 43).

Therefore, by studying the modular components of the assembly line, we can add, remove, or edit modules of the assembly line to produce novel antibiotic products. In the papers below, the researchers propose new assembly lines, based off of assembly lines naturally occurring in nature, and study the novel products that are produced. The significance of these papers is that now, we can produce novel polyketide chains for antibiotic use, given that we know the product that we want to synthesize.

Systems biology integrates computational modelling with experimental techniques in order to better understand the function of living organisms, the regulation of their cellular processes and how these cells react to environmental perturbations [1]. Among the different computational approaches, kinetic modelling gives the most detailed representation of the biological system. These models build on the stoichiometry of the reactions, incorporating the dynamic interactions between different components of the network. The dynamics in kinetic models are driven through ordinary differential equations (ODEs) that represent the internal reaction mechanism as a function of species concentration and parameters. These model parameters play a crucial role in describing the correct dynamics of the model. However, it is only possible to measure a fraction of these kinetic parameters in wet lab experiments due to high cost, difficulty and limitations in current techniques or methods [2]. Therefore these parameters are indirectly determined through computational methods from other measurement quantities, in particular the time course data of metabolite concentrations. However, as biological models are often multi-modal it is not uncommon for traditional parameter estimation methods to become stuck in local optima [3]. In addition, traditional methods tend to perform badly in the presence of high measurement noise. Furthermore most of these methods do not consider any form of model

Task 2: Once we arrive at the upper-bound of the crystal cavity size, we will use computational models of these crystals to screen for large number of candidate enzymes that we can successfully encapsulate within the crystal lattice.
