This process is called “photosynthesis” (meaning literally “to put together with light”) and is the cornerstone of life on Earth. In photosynthesis, the sun’s energy combines the hydrogen from water (H20) with carbon dioxide (CO2), producing glucose (C6H12O6) and oxygen (O2), which is given off as a …

The star that is the center of the solar system and that sustains life on Earth because it is the source of light and heat for the Earth. Also, any star that is the center of a planetary system. star. A self-luminous celestial body consisting of a mass of gas held together by its own gravity and generating energy by nuclear reactions in its ...

Accessory pigments absorb light at different wavelengths than chlorophyll and transfer the energy to chlorophyll a for use in photosynthesis. The food storage product of blue green algae, cyanophycean starch, is chemically similar to the glycogen produced by animals.

These reactions are redox reactions where one metal ion is reduced to its elemental state and another more active metal is oxidized to an ionic state. For example, 2Na + Fe+2 ( 2Na+ + Fe. Although hydrogen has many physical and chemical properties that are similar to nonmetals, it frequently functions chemically as a metal, and for this reason ...

Hence, the first step in photosynthesis is the absorption of visible light from the sun by chlorophyll molecules. The chlorophyll molecules then transfer the light energy to chloroplasts, the reaction center of photosynthesis. In this way light energy is converted to …

They examine how biochemical pathways, specifically photosynthesis and cellular respiration, involve many steps that are controlled by enzymes and assisted by coenzymes. Students investigate factors that affect the rate of cellular reactions and explore applications of biotechnology that focus on the regulation of biochemical pathways.
