Sample Critical Thinking Paper on Evaluation of Light-induced Electron Transfer and ATP Synthesis in a Carotene Synthesizing Insect

The article is peer-reviewed. That is, other scholars have scrutinized the research including the methodology and conclusion on the external aphid extracts. The research focused on various areas including environmental chemistry, gene flow, metabolism, and plasticity. During the investigation, the authors claimed not to be having any competing financial interest and provided a website link where additional information concerning this particular article and their ideas can be traced.

The authors of this article work at Institute of Plant Protection in France in various capacities including as a scientist and Environmental Chemistry Research Consultants, among other related science courses. According to the level of research and documentation done in this article, it is right to conclude that they have vested interests in undertaking their tasks.

This scientific research has no hypothesis. The research focused on the influence of scientific characteristics of aphids on the rate of light-induced electron transfer. The study also sought to determine the general process through which ATAP is synthesized in some of the carotene-synthesizing insects with a special focus on aphids.

This article used a dichotomous simplification writing style. It begins with the scientists making an agreement to settle on aphid as the best available carotene synthesizing insect. They then decide to use two types of aphids: the green and orange aphids. This is a simplification as the aphids are divided into two parts with respect to their colors: green and orange (Valmalette et al. 3). They follow this by undertaking an extensive comparative study on each insect by use of mass spectrometry.  Initially, they make the chromatographically isolation, which is another stage of dichotomous simplification. This assists in the objectivity of quantification process with respect to the available intermediate components for the entire synthesis of carotenoid.

The arguments raised in this article are based on the observation made on the performed experiments. They argue that the two major types of aphids are enzymes that get fused in a single protein having two distinct catalytic processes. They also argue that some of the key enzymes, particularly those found in the carotenoid synthesis, must be located in different sections of the aphid genome. This is because they exhibited differing rates of reaction despite the fact that they were all set to the same medium and provided similar timing.

The particular evidence in this article was gathered through scientific methods. This is based on the fact that they conducted research, did an experiment and came up with a conclusion. All the evidenced were based on reality, without any speculations, having set other aphids to act as control experiments, hence improving on the validity of their testimony.

All the percentages provided in the experiments do not add up to 100%. This is due to the emissions of some reactants and intrusion of some environmental variables into the experiment. During the process of making the precipitate soluble not all of them dissolved in the acetone used, hence one of the deductions towards the intended 100% (Valmalette et al. 3). The comparative spectrum with respective to absorbance did not take place as per the indicated and suggested lengths, providing another loop for divergence from the intended 100%.



The conclusions are based on the review of data as well as the original statement of this discovery science. Through the whole experiment, some of the major components, for both the green and orange aphids, have been tabulated. The tabulated figures have been used in plotting the graphs and come up a vivid conclusion, based on the diagrammatical findings and representation.
