WebBiology questions and answers. 6. Muscle contraction is associated with elevated levels of cytosolic calcium. Which statement describes a consequence of this increase in calcium? a. An increased level of calcium is associated with an increase in glycogen breakdown, as calcium is an allosteric activator of phosphorylase b kinase b. Calcium is a ... WebOct 1, 1999 · Abstract—Elevated cytosolic free calcium (Ca i) and reciprocally reduced, extracellular ionized calcium (Ca-ion) levels are observed in both hypertension and non–insulin-dependent diabetes mellitus (NIDDM).Because the changes of vascular function and insulin sensitivity in these conditions resemble the changes associated with “normal” …
WebIonized calcium is the physiologically active form. Cytosolic ionized calcium is maintained within the micromolar range (1/1000 of the serum concentration).Ionized calcium acts as … Webincreased cytosolic free calcium concentration ([Ca’+],) which occurs somewhat asynchronously in primary cultured hepa- tocytes. An additional benefit of carrying out these studies at the single cell level was that the temporal relationships be- tween changes in [Ca2+]i and cell death could be determined ...
WebFor example, all intracellular calcium channels are modulated by the luminal and cytosolic calcium concentration and therefore barium is often chosen as a current carrier not affecting channel function [5, 12-14]. ...
