2. Adenosine diphosphate - Wikipedia

   en.wikipedia.org/wiki/Adenosine_diphosphate

   Chemical compound. Adenosine diphosphate(ADP), also known as adenosine pyrophosphate(APP), is an important organic compoundin metabolismand is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugarbackbone attached to adenineand two phosphategroups bonded to the 5 carbon atom of ribose.

3. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   To use this stored chemical energy, an organism's cells metabolize the organic compounds through cellular respiration. Photosynthesis plays a critical role in producing and maintaining the oxygen content of the Earth's atmosphere, and it supplies most of the biological energy necessary for complex life on Earth.

4. Adenine - Wikipedia

   en.wikipedia.org/wiki/Adenine

   Function. Adenine is one of the two purine nucleobases (the other being guanine) used in forming nucleotides of the nucleic acids. In DNA, adenine binds to thymine via two hydrogen bonds to assist in stabilizing the nucleic acid structures. In RNA, which is used for protein synthesis, adenine binds to uracil.

5. Flavin adenine dinucleotide - Wikipedia

   en.wikipedia.org/wiki/Flavin_adenine_dinucleotide

   In biochemistry, flavin adenine dinucleotide (FAD) is a redox -active coenzyme associated with various proteins, which is involved with several enzymatic reactions in metabolism. A flavoprotein is a protein that contains a flavin group, which may be in the form of FAD or flavin mononucleotide (FMN). Many flavoproteins are known: components of ...

6. Hill reaction - Wikipedia

   en.wikipedia.org/wiki/Hill_reaction

   Hill reaction. Plant cells with visible chloroplasts (from a moss, Plagiomnium affine) The Hill reaction is the light-driven transfer of electrons from water to Hill reagents (non-physiological oxidants) in a direction against the chemical potential gradient as part of photosynthesis. Robin Hill discovered the reaction in 1937.

7. ATP synthase - Wikipedia

   en.wikipedia.org/wiki/ATP_synthase

   ATP synthase is an enzyme that catalyzes the formation of the energy storage molecule adenosine triphosphate (ATP) using adenosine diphosphate (ADP) and inorganic phosphate (P i). ATP synthase is a molecular machine. The overall reaction catalyzed by ATP synthase is: ADP + P i + 2H +out ⇌ ATP + H 2 O + 2H +in.

8. Light-dependent reactions - Wikipedia

   en.wikipedia.org/wiki/Light-dependent_reactions

   Light-dependent reactions of photosynthesis at the thylakoid membrane. Light-dependent reactions are certain photochemical reactions involved in photosynthesis, the main process by which plants acquire energy. There are two light dependent reactions: the first occurs at photosystem II (PSII) and the second occurs at photosystem I (PSI).

9. Photosynthetic efficiency - Wikipedia

   en.wikipedia.org/wiki/Photosynthetic_efficiency

   Fraction of light energy converted into chemical energy during photosynthesis in plants and algae. The photosynthetic efficiencyis the fraction of light energy converted into chemical energyduring photosynthesisin green plants and algae. Photosynthesis can be described by the simplified chemical reaction. 6 H2O + 6 CO2+ energy → C6H12O6+ 6 O2.
