|---|---|
| Adenosine triphosphate | Adenosine is a purine nucleoside comprising a molecule of adenine attached to a ribose sugar molecule. |
| autotroph | An autotroph[α],(self-feeding) or producer, is an organism that produces complex organic compounds. |
| heterotroph | is an organism that cannot fix carbon and uses organic carbon for growth |
| photosynthesis | is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. |
| pigment | a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption |
| chlorophyll | is a green pigment found in almost all plants. |
| thylakoid | A membrane-bound compartment inside chloroplasts and cyanobacteria. |
| stroma | the connective, functionally supportive framework of a biological cell, tissue, or organ |
| NADP | Nicotinamide adenine dinucleotide phosphate. |
| light-dependent reactions | first stage of photosynthesis. |
| light-independent reactions | chemical reactions that convert carbon dioxide and other compounds into glucose. |
| photosystem | functional and structural units of protein complexes |
| electron transport chain | electron transfer between an electron donor (such as NADH) and an electron acceptor (such as O2) with the transfer of H+ ions (protons) across a membrane. |
| ATP synthase | important enzyme that provides energy for the cell to use through the synthesis of adenosine triphosphate. |
| Calvin cycle | a series of biochemical redox reactions that take place in the stroma of chloroplasts in photosynthetic organisms. |
