Parathyroid Hormone-dependent Uptake of Inorganic Phosphate by Mitochondria.
The role of the parathyroid hormone in the regulation of calcium and phosphate metabolism has been recognized for many years (1). At the cellular level, the hormone is thought to regulate calcium and phosphate transport reactions. It is now known to (a) increase calcium reabsorption in the renal tubule (2, 3), (b) increase the transport of calcium across intestinal membranes (a, 5), (c) increas...
متن کاملProton / Phosphate Stoichiometry in Uptake of Inorganic Phosphate by Cultured Cells of Catharanthus roseus ( L . )
Upon absorption of phosphate, cultured cells of Catharanthus roseus (L.) G. Don caused a rapid alkalinization of the medium in which they were suspended. The alkalinization continued until the added phosphate was completely exhausted from the medium, at which time the pH of the medium started to drop sharply toward the original pH value. Phosphate exposure caused the pH of the medium to increas...
متن کاملPhosphate addition enhanced soil inorganic nutrients to a large extent in three tropical forests
Elevated nitrogen (N) deposition may constrain soil phosphorus (P) and base cation availability in tropical forests, for which limited evidence have yet been available. In this study, we reported responses of soil inorganic nutrients to full factorial N and P treatments in three tropical forests different in initial soil N status (N-saturated old-growth forest and two less-N-rich younger forest...
متن کاملSeasonal hydrochemical variation in a tropical coastal lagoon (Açu Lagoon, Brazil).
Hydrochemical conditions in the Açu Lagoon are described using spatial and temporal variations of various limnological variables (water temperature, dissolved oxygen, electric conductivity, total alkalinity, carbon dioxide, dissolved and total nutrients (N, P and Si), and chlorophyll a). Collected data was used in order to understand the structure and functioning of an enclosed coastal lagoon s...
متن کاملDistribution of picophytoplankton communities from brackish to hypersaline waters in a South Australian coastal lagoon
BACKGROUND Picophytoplankton (i.e. cyanobacteria and pico-eukaryotes) are abundant and ecologically critical components of the autotrophic communities in the pelagic realm. These micro-organisms colonized a variety of extreme environments including high salinity waters. However, the distribution of these organisms along strong salinity gradient has barely been investigated. The abundance and co...
