Reversible swelling and contraction of isolated spinach chloroplasts.
By use of a micro technique for producing extracts of spinach mesophyll cells, chloroplasts were isolated in a state wherein they displayed microscopically visible, reversible osmotic properties. Swollen spherical chloroplasts treated with hypertonic sucrose or mannitol media, but not NaCl, could be shrunken to a state resembling their disk appearance in living cells. Reversible osmotic behavio...
متن کاملIsolated Chloroplasts
1. Chloroplasts prepared by the non-aqueous technique will, after fragmentation by ultrasonic treatment, incorporate [2-14C]mevalonic acid into phytoene, the first C40 compound formed in the biosynthetic sequence to coloured carotenoids. 2. With suspensions containing 3*5mg. of chlorophyll, the optimum amounts of cofactor required were ATP (10,umoles), magnesium chloride (20,umoles) and glutath...
متن کاملEngineering Properties and Shrinkage Limit of Swelling Soils in Greece
The existence of specific expansive minerals in the clay soil related to the climatological conditions, seasonable variation of rainfall precipitation (wet and dry periods) and fluctuation of water table in Mediterranean countries, has resulted to induce unexpected shrinkage and swelling movements with all the unfavourable consequences. It was observed that light industrial structures and small...
متن کاملMeasurement of experimentally induced brain swelling and shrinkage.
White et al. (I, 2) have measured changes in brain volume in cats by careful determinations of the volume of the brain and of the cranial cavity. The normal difference between these two volumes is about IO per cent and variation from this figure represents swelling or shrinkage of the brain. This method is difkult, and could hardly be applied after craniotomy. Assuming that changes in brain vol...
متن کاملPhotosynthesis by isolated chloroplasts.
Photosynthesis in green plants requires not only photoelectron transport, oxygen evolution, and photophosphorylation, but also the synthetic reactions whereby carbon dioxide is assimilated and reduced to a number of organic compounds via the photosynthetic carbon reduction cycle1 and secondary biosynthetic pathways.2 Complete photosynthesis with isolated chloroplasts has for many years been a g...
