Chemical Character and Physiological Action of the Potassium Ion
1. It is shown that the NH(4) ion acts in cases of antagonism on the egg of Fundulus more like the K ion than the Na ion; this corresponds to the fact that in its general chemical behavior the NH(4) ion resembles the K ion more closely than the Na ion. 2. It is shown that the tolerance of sea urchin eggs towards the Li ion can be increased 500 per cent or more if at the same time a certain amou...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
The significance of potassium
The human body contains about 3,500mmol of potassium. Only about 2 per cent of this is in the extracellular fluid at any one time and the rest is intracellular. This 98 per cent is held in cells by a set of complex mechanisms and is pumped in and out of them by Na/K-ATPase pumps. Potassium has many biological functions. It is a co-factor for many enzymes and it is required for insulin secretion...
متن کاملThe mutual independence of the endolymphatic potential and the concentrations of sodium and potassium in endolymph.
The relationship between the endolymphatic potential (EP) and the sodium and potassium concentration gradients between endolymph and interstitial fluid was studied both by measuring the EP at varying concentrations of sodium and potassium in endolymph and by measuring the effect of a depressed EP on the concentrations of these cations. Ethacrynic acid was used in dogs to change the concentratio...
متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
