Hi, need to submit a 2000 words paper on the topic Contribution of Mitochondria to the Cellular Energy Budget and the Ethical Implications of Mitochondrial DNA. The best sources of cellular energy are those rich in hydrocarbons due to the presence of hydrogen electrons, which are readily oxidized. The oxidized electrons provide the required energy. There are numerous organic compounds that can be oxidized, but glucose serves as the main fuel molecule for cells, hence the term glucose metabolism or glucose oxidation. The two terms are used interchangeably to refer to pathways involved in cellular respiration. Glucose is derived from photosynthesis. Examples of organic foods that are rich sources of energy include sugars, fats, and proteins. This is because the energy used in the synthesis of these food products is stored in chemical bonds holding the molecules (Karp 2009, p119).
