| Z scheme of photosynthesis | <biochemistry, biology> A schematic representation of the light reactions of photosynthesis, in which the photosynthetic reaction centres and electron carriers are arranged according to their electrode potential (free energy) in one dimension and their reaction sequence in the second dimension. This gives a Z shape, the two reaction centres (of photosystems I and II) being linked by the photosynthetic electron transport chain. (18 Nov 1997) |

| scheme | 1. A combination of things connected and adjusted by design; a system. "The appearance and outward scheme of things." (Locke) "Such a scheme of things as shall at once take in time and eternity." (Atterbury) "Arguments . . . Sufficient to support and demonstrate a whole scheme of moral philosophy." (J. Edwards) "The Revolution came and changed his whole scheme of life." (Macaulay) 2. A plan or theory something to be done; a design; a project; as, to form a scheme. "The stoical scheme of supplying our wants by lopping off our desires, is like cuttig off our feet when we want shoes." (Swift) 3. Any lineal or mathematical diagram; an outline. "To draw an exact scheme of Constantinople, or a map of France." (South) 4. <astronomy> A representation of the aspects of the celestial bodies for any moment o at a given event. "A blue case, from which was drawn a scheme of nativity." (Sir W. Scott) Synonym: Plan, project, contrivance, purpose, device, plot. Scheme, Plan. Scheme and plan are subordinate to design; they propose modes of carrying our designs into effect. Scheme is the least definite of the two, and lies more in speculation. A plan is drawn out into details with a view to being carried into effect. As schemes are speculative, they often prove visionary; hence the opprobrious use of the words schemer and scheming. Plans, being more practical, are more frequently carried into effect. "He forms the well-concerted scheme of mischief; 'T is fixed, 't is done, and both are doomed to death." (Rowe) "Artists and plans relieved my solemn hours; I founded palaces, and planted bowers." (prior) Origin: L. Schema a rhetorical figure, a shape, figure, manner, Gr, form, shape, outline, plan, fr, to have or hold, to hold out, sustain, check, stop; cf. Skr. Sah to be victorious, to endure, to hold out, AS. Sige victory, G. Sieg. Cf. Epoch, Hectic, School. Source: Websters Dictionary (01 Mar 1998) |

| occlusal scheme | The form or design and arrangement of the occlusal and incisal units of a dentition or the teeth on a denture. Synonym: occlusal scheme. (05 Mar 2000) |
| anoxygenic photosynthesis | A type of photosynthesis in green and purple bacteria in which oxygen is not produced. Use of light energy to synthesise ATP by cyclic photophosphorylation without oxygen production in green and purple bacteria. (09 Oct 1997) |
| photosynthesis | <biochemistry, biology> Process by which green plants, algae and some bacteria absorb light energy and use it to synthesise organic compounds (initially carbohydrates). In green plants, occurs in chloroplasts, that contain the photosynthetic pigments. Occurs by slightly different processes in C3 and C4 plants. (18 Nov 1997) |
| oxygenic photosynthesis | Use of light energy to synthesise ATP and NADPH by noncyclic photophosphorylation with the production of oxygen from water. (09 Oct 1997) |
