PHOTOSYNTHESIS - SOLAR NAVIGATOR
The energy for photosynthesis ultimately comes from absorbed photons and involves a reducing agent, which is water in the case of plants, releasing oxygen as a waste product. The light energy is converted to chemical energy, in the form of ATP and NADPH, using the light-dependent reactions and is then available for carbon fixation.

USING HYDROGEN AS A NUCLEOPHILE IN HYDRIDE REDUCTIONS
Like carbon, hydrogen can be used as a nucleophile if it is bonded to a metal in such a way that the electron density balance favors the hydrogen side. A hydrogen atom that carries a net negative charge and bears a pair of unshared electrons is called a hydride ion..
gcse 2. Blast furnace extraction of iron recycling, steel …
The carbon monoxide, CO, is known as the reducing agent because it is the oxygen (O) remover and gets oxidised to carbon dioxide in the process (CO gains oxygen). This frees the iron, which is molten at the high blast furnace temperature, and trickles down to the base of the blast furnace and run off.
The energy for photosynthesis ultimately comes from absorbed photons and involves a reducing agent, which is water in the case of plants, releasing oxygen as a waste product. The light energy is converted to chemical energy (known as light-dependent reactions ), in the form of ATP and NADPH , which are used for synthetic reactions in photoautotrophs.
Sodium Borohydride - an overview | ScienceDirect Topics
Sodium borohydride is considered to be a selective reagent, 31 which means that it is a weaker reducing agent when compared to LiAlH 4 (e.g., see Section 7.6). Sodium borohydride is useful for the reduction of aldehydes, ketones, or acid chlorides in the presence of other easily reducible functional groups . 32 The relatively poor reactivity of sodium borohydride is reflected in the solvents
CHEMICAL REACTIONS AND EQUATIONS
2/8/2018· Reducing agent: Compounds or elements which can cause reduction are called reducing agents. In a chemical reaction oxidation and reduction both take place simultaneously and such reactions are also known as REDOX REACTIONS.
Electrochemistry O - Corrosion
Electrochemistry Dictionary - O Ω: Syol and abbreviation of ohm.(The syol is the "Greek capital omega" letter, some browsers unfortunately do not support this.) OCP: Stands for open-circuit potential. See equilibrium potential. OCV: Stands for open circuit voltage.
Chapter 6 Oxidation-Reduction Reactions
another. These reactions are called oxidation-reduction reactions (or redox reactions). This section provides examples of these reactions and introduces the terms oxidation, reduction, oxidizing agent, and reducing agent, which are summarized in Figure 6.2.
Summary The three types of carbohydrates are monosaccharides, disaccharides and polysaccharides Monosaccharides are the simplest sugars e.g. glucose. fructose and galactose Disaccharides are formed by condensation where there is linking of two monosaccharides together Disaccharides can be broken down to monosaccharides via hydrolysis Polysaccharides, also known as polymers contain three or
What Decarbonization Means for Cows, Steel and …
1/10/2019· Thyssenkrupp AG uses carbon dioxide and other gases released in the steel production process as raw materials for making chemicals, reducing overall emissions. Why Steel Pollutes So Much
Reduction of Metals (Extraction from Ore) - A-Level …
In many cases, carbon cannot be used to reduce the metal oxide to the metal as the metal reacts with carbon to form the carbide instead. It is possible to avoid this problem by first converting the ore to the chloride, and then reducing the chloride with a more reactive metal such as magnesium or sodium.
Vitamin C: An Antioxidant Agent | IntechOpen
4/11/2016· Plant and animal cells contain an NADH-dependent semidehydroascorbate reductase enzyme (EC 22.214.171.124), reducing the radical back to vitamin C by using NADH as a source of reducing agent (). Both enzymatically and nonenzymatically, it can irreversibly decompose into diketogluconic acid or it can be converted to ascorbate in a glutathione-dependent reaction [ 3 , 13 , 14 ].
