How does bioenergetics relate to the news today

In their paper Nick Lane UCL, Genetics, Evolution and Environment and Bill Martin University of Dusseldorf address the question of where all this energy came from - and why all life as we know it conserves energy in the peculiar form of ion gradients across membranes.

Living organisms require vast amounts of energy to go on living," said Nick Lane. It is possible to trace a coherent pathway leading from no more than rocks, water and carbon dioxide to the strange bioenergetic properties of all cells living today. Humans consume more than a kilogram more than litres of oxygen every day, exhaling it as carbon dioxide. The simplest cells, growing from the reaction of hydrogen with carbon dioxide, produce about 40 times as much waste product from their respiration as organic carbon by mass.

In all these cases, the energy derived from respiration is stored in the form of ion gradients over membranes. This strange trait is as universal to life as the genetic code itself.

A new study introduces a statistical mechanical framework that draws on biophysical data from SH2 domain—phosphoprotein interactions to predict the functional effects of mutations in cancer. Research Highlights 06 November Advanced search. Skip to main content Thank you for visiting nature.

Atom RSS Feed Bioenergetics Definition Bioenergetics is the branch of biochemistry that focuses on how cells transform energy, often by producing, storing or consuming adenosine triphosphate ATP. Latest Research and Reviews Research 11 November Open Access Structural dynamics in the water and proton channels of photosystem II during the S 2 to S 3 transition The oxygen-evolving complex in Photosystem II PSII catalyzes the light-driven oxidation of water to oxygen and it is still under debate how the water reaches the active site.

Nature Communications 12 , Nature , Instead, they want to develop a blood test to rapidly assess how well the body is truly processing oxygen via the mitochondria.

They published results from a preliminary pilot study of one such method using patient blood cells in the journal Clinical Toxicology in July. Their pilot study showed the test of mitochondrial functioning could be conducted quickly enough to be clinically useful. They are now pursuing larger studies and similar studies with sepsis, a severe form of infection that is the leading cause of patient deaths in intensive-care settings.

To work toward developing future bioenergetics-focused therapies, they can begin with an existing part of their assessments of how well mitochondria are working. In this process, they systematically disrupt each of several distinct steps in the process by which mitochondria consume oxygen and create energy for the cell.

In unhealthy mitochondria, this gives an indication of which specific steps are in need of repair. If drugs that help skip past the broken steps can be successfully delivered directly into the mitochondria — something Eckmann and Jang, among others, are attempting with a type of drugs called prodrugs — then someday a whole new class of therapies might be possible to treat bioenergetics aspects of disease, wherever they might manifest in the body.
