PS 50-152: The relationship between photosynthesis and respiration is not primarily regulated through carbohydrates in a desert shrub ([L])The intermediary role of carbohydrate levels is assumed to be of key importance in regulating net photosynthetic rates and respiration rates. A shading experiment ...
The rates of respiration for all the studied species increase linearly with increasing temperature from 18 to 35℃. The optimum salinities for photosynthesis range from 26 to 32 for two species of Gracilaria, whose respiratory rates decrease gradually with increasing salinity. 展开 年份: 1986 ...
This process is extremely important to life on Earth as it provides an energy source, food, and oxygen to living things; without this process, life would not exist. Cellular respiration is the exact opposite of photosynthesis as it is the process of breaking down food....
High rates of photosynthesis and polysaccharide synthesis in the light were followed by high rates of respiration and polysaccharide utilization in the dark. Polysaccharide was the major respiratory substrate in the dark, and small molecular weight metabolites, lipids, and protein were less important ...

Dark respiration was higher in leaves of wild species than in the two genotypes of A. hypogaea. Diffusive resistance of A. hypogaea, A. pintoi and A. sp. (glabrata?) leaves remained constant from 9 a.m. to 3 p.m. EST and then increased up to the last measurement at 10 p.m. The...
Mass spectrometric analysis of oxygen uptake and evolution in the light by marine Synechococcus WH7803 indicated that the respiration rate was near zero at low irradiance levels but increased significantly at high irradiances. The light intensity (I r ) at which oxygen uptake began to increase with...
Eukaryotic organisms include plants that carry out photosynthesis to produce their own foods, and animals that eat plants and other animals. One of the main processes involved in cellular respiration is glycolysis. Glycolysis is a metabolic process that takes place in the cytoplasm of the cell. ...
What is the structure of glucose? What is dehydration synthesis, and what does it do in the glucose-to-glycogen process? What is the relationship between photosynthesis and cellular respiration? What is the structural difference between starch and glycogen?
If the sink organs regulate the metabolic activity of the source organs through the transmission of a signal and that signal is chemical in nature, then it should be present among the substances coming out of the panicle. When flag leaf respiration and photosynthesis of wheat ( Tritcum aestivum...
