Four autotrophic carbon-fixation pathways were already known ... this cycle in carbon fixation. The first reaction in the 3-hydroxypropionate carbon dioxide-fixation cycle is the carboxylation ...

Electrochemical CO2 reduction (ECR) driven by green electricity represents a promising strategy for CO2 mitigation and utilization by producing fuels ...

The term greenhouse gas often brings carbon dioxide (CO2) to mind, and rightly so, as it is a key contributor to rising ...

‘We found a distinctly different pathway to produce O2 from molecular CO2,’ Tian said. ‘Namely, through the reaction of ...

Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

Conventional carbon dioxide (CO2) conversion technologies ... between two metal atoms to actively regulate the reaction pathway and maximize efficiency. The research team applied the aerosol ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a ...

A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic acid ...

Oxidation describes a type of chemical reaction in which electrons ... they are released as waste in the form of carbon dioxide (Figure 3). The particular energy pathway that a cell employs ...

One way that chemists recycle CO 2 into valuable products is through a process called electrochemical reduction, where a ...

Catabolic – this type of pathway releases energy and is used to break down large molecules into smaller ones (degradation). An example of an anabolic reaction is photosynthesis, where plants ...

altering the reaction pathway entirely. "Our research proposes a new pathway for efficient hydrogen production without CO2 emissions," said Ma Ding, a researcher at Peking University. The study ...
