DEF

The synthesis of organic matter from carbon dioxide and water in the presence of light by living organisms, employing photochemically reactive pigments.

CONT

Photosynthesis is the chemical process where plants and some bacteria can capture and organically fix the energy of the sun.... The main product of photosynthesis is a carbohydrate, such as the sugar glucose, and oxygen which is released to the atmosphere. All of the sugar produced in the photosynthetic cells of plants and other organisms is derived from the initial chemical combining of carbon dioxide and water with sunlight. This chemical reaction is catalyzed by chlorophyll acting in concert with other pigment, lipid, sugars, protein, and nucleic acid molecules. Sugars created in photosynthesis can be later converted by the plant to starch for storage, or it can be combined with other sugar molecules to form specialized carbohydrates such as cellulose, or it can be combined with other nutrients such as nitrogen, phosphorus, and sulfur, to build complex molecules such as proteins and nucleic acids.

DEF

Synthèse de matière organique à partir de gaz carbonique et d'eau, en présence de lumière, par des organismes vivants utilisant des pigments réagissant photochimiquement.

CONT

Toute la matière vivante découle plus ou moins directement de ce phénomène que l'on appelle aussi «assimilation chlorophyllienne». La photosynthèse est un phénomène très complexe qui donne lieu à divers types de réactions chimiques. Les unes sont dites claires, car elles dépendent directement de la lumière et assurent les transformations proprement photochimiques; les autres, dites obscures, précèdent ou prolongent ces transformations photochimiques vers des synthèses organiques, ou la reconstitution de molécules organiques servant aux transferts d'énergie.

Record 2 2003-07-14

English

Subject field(s)
  • Chemical Elements and Compounds
CONT

Liquid chlorine and liquid sulfur dioxide are used at the Water Pollution Control Plant in the treatment of wastewater and in the production of reclaimed water.

CONT

Sulfur dioxide gas is intensely irritating to the eyes, throat, and upper respiratory system. Liquid sulfur dioxide may cause skin burns, which result from the freezing effect of the liquid on tissue.

CONT

Sulphur dioxide is either converted into sulphuric acid or liquid sulphur dioxide, or is emitted in gaseous form into the atmosphere.

French

Domaine(s)
  • Éléments et composés chimiques
CONT

Le dioxyde de soufre peut se transformer en acide sulfurique ou en dioxyde de soufre liquide ou gazeux. Une fois dans l'atmosphère, le dioxyde de soufre réagit avec d'autres gaz et avec l'humidité de l'air ambiant pour produire des précipitations acides.
