Depiction of the book of life. In Judaism and Christianity, the Book of Life (Biblical Hebrew: ספר החיים, transliterated Sefer HaḤayyim; Ancient Greek: βιβλίον τῆς ζωῆς, romanized: Biblíon tēs Zōēs Arabic: سفر الحياة, romanized: Sifr al-Ḥayā) is an alleged book in which God records, or will record, the names of every person who is destined for Heaven ...
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
Oxidation response is stimulated by a disturbance in the balance between the production of reactive oxygen species and antioxidant responses, known as oxidative stress. Active species of oxygen naturally occur in aerobic cells and have both intracellular and extracellular sources.
The oxidation reaction that converts adrenaline into adrenochrome occurs both in vivo and in vitro. Silver oxide (Ag 2 O) was among the first reagents employed for this, [ 2 ] but a variety of other oxidising agents have been used successfully. [ 3 ]
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
"Alcohol has a half-life of four to five hours, so if you drink at happy hour at, say, 6 p.m., that alcohol will stick with you until around 11 p.m., which can be way too late to fall asleep ...
Free oxygen is produced in the biosphere through photolysis (light-driven oxidation and splitting) of water during photosynthesis in cyanobacteria, green algae, and plants. During oxidative phosphorylation in cellular respiration, oxygen is reduced to water, thus closing the biological water-oxygen redox cycle.
