Carbon Dioxide Diffusion inside Leaves
Leaves are beautifully specialized organs that enable plants to intercept light necessary for photosynthesis. The light is dispersed among a large array of chloroplasts that are in close proximity to air and yet not too far from vascular tissue, which supplies water and exports sugars and other metabolites. To control water loss from the leaf, gas exchange occurs through pores in the leaf surfa...
متن کاملPhotosynthetic path of carbon dioxide in spinach and corn leaves.
The primary route of COn incorporation in C-4 plants (corn) has been formulated to be fi-carboxylation catalyzed by phosphoenolpyruvate carboxylase, while in C-3 plants (spinach) COZ enters the carboxyl carbon of glycerate 3-phosphate after reacting with ribulose 1,5-diphosphate. Detached leaf tissues of spinach and corn were compared with respect to their fixation of CO* in the dark or in the ...
متن کاملCytotoxic Deoxypodophyllotoxin Can Be Extracted in High Purity from Anthriscus sylvestris Roots by Supercritical Carbon Dioxide.
Deoxypodophyllotoxin is present in the roots of Anthriscus sylvestris. This compound is cytotoxic on its own, but it can also be converted into podophyllotoxin, which is in high demand as a precursor for the important anticancer drugs etoposide and teniposide. In this study, deoxypodophyllotoxin is extracted from A. sylvestris roots by supercritical carbon dioxide extraction. The process is sim...
متن کاملVariations in Respiratory Excretion of Carbon Dioxide Can Be Used to Calculate Pulmonary Blood Flow
BACKGROUND A non-invasive means of measuring pulmonary blood flow (PBF) would have numerous benefits in medicine. Traditionally, respiratory-based methods require breathing maneuvers, partial rebreathing, or foreign gas mixing because exhaled CO2 volume on a per-breath basis does not accurately represent alveolar exchange of CO2. We hypothesized that if the dilutional effect of the functional r...
متن کاملCan increasing carbon dioxide cause climate change?
The realistic physical functioning of the greenhouse effect is reviewed, and the role of dynamic transport and water vapor is identified. Model errors and uncertainties are quantitatively compared with the forcing due to doubling CO2, and they are shown to be too large for reliable model evaluations of climate sensitivities. The possibility of directly measuring climate sensitivity is reviewed....
