Document Summary

High concentrations of substrates such as adp and nad+ indicate a low energy state in the cell and stimulate the respiratory pathways. High concentrations of products such as atp and nadh indicate a high energy state in the cell and inhibit the respiratory pathways. Plants, like the trees outside, get most of their biomass (mass of biological macromolecules) from the air. Photosynthesis occurs in the chloroplasts of green plants, algae, and other photosynthetic organisms. Converting light energy to cellular energy (energy intermediates) 6 carbon intermediate splits into 2 3 carbon intermediates (3pg: reduction and carbohydrate production. 6 co2 -> (cid:1005)(cid:1006) g(cid:1007)p (cid:894)6 rubp+ 6 co(cid:1006)(cid:895) (cid:1006) or sugar (cid:894)(cid:272)ar(cid:271)s(cid:895), (cid:1005)(cid:1004) for regeneration of rubp: regeneration of rubp. 10 g3p converted into 6 rubp using 6 atp. 60% of the suns output is outside the visible range and unavaiable for photosynthesis. Plats get most of their biomass from carbon dioxide. What allows all multicellular organisms to work together.
