Linking bioenergetics to everyday challenges
BioenergyThrough bioenergetics studies biochemists are able to understand how energy released during cellular metabolism can be used to “do work” that is useful for the cells e.g. movement of molecules, cells or organs or heating within a body. Similar types of studies and knowledge allow biochemists to appreciate how to harness energy from biological systems, or to make them more efficient. For example, the process of photosynthesis is inspiring solutions to the growing demand for sustainable energy, in the form of novel biofuels and advanced biotechnology products that can convert solar energy into a useful form.
Chemical Effects on the EnvironmentNitrogen is a key component of all cells and it is required for them to be able to synthesise the amino acids of proteins and the nucleotides that are important for the synthesis of DNA and RNA. Therefore, the deeper appreciation of nitrogen metabolism that biochemists will supply will allow the generation of more efficient systems. Some microbes rely on anaerobic nitrate respiration, or denitrification pathways, to generate metabolic energy by using nitrate as a terminal electron acceptor of the electron transport chains. These denitrification pathways generate several intermediates, including nitric oxide and nitrous oxide, which are significant greenhouse gases.© UEA and Biochemical Society, 2018.
