Description:
Antidiuretic hormone (ADH)-induced luminal intramembranous particle aggregates and hormonally stimulated water flow in toad urinary bladder are reduced simultaneously with a reduction in temperature. When water movement is factored by the aggregation response, the apparent activation energy for this process decreases from 12.1 +/- 1.6 to 3.0 +/- 2.3 kilocalories per mole. The data are consistent with the view that the particle aggregates contain sites for transmembrane water movement and that these sites behave as pores.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kachadorian, W A -- Muller, J -- Rudich, S W -- DiScala, V A -- New York, N.Y. -- Science. 1979 Aug 31;205(4409):910-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/112678" target="_blank"〉PubMed〈/a〉
