Increased cytosolic calcium
WebIncreases in cytosolic free calcium concentration ([Ca2+]I) may play an important role in myocardial ischemic injury. An early effect of the rise in [Ca2+]I may be impaired postischemic contractile function if the ischemic myocardium is reperfused during the reversible phase of ischemic injury; furthermore, if the rise in [Ca2+]I is prolonged, a … WebJan 25, 2024 · Increased cytosolic calcium generated during synaptic activity also acts to halt mitochondrial trafficking, resulting in mitochondrial accumulation near active …

WebAug 15, 2000 · A prolonged decay of Ca(2+) signals in mutant boutons at high temperatures indicated abnormally slow Ca(2+) clearance. Cytosolic Ca(2+) at rest was determined with the ratiometric Ca(2+) indicator fura-2 AM and was similar in mutant and control boutons at 24 degrees C but higher in mutant boutons at 34 degrees C. Webincreased cytosolic calcium, which binds to calmodulin in cytosol, complex binds with myosin light-chain kinase, which uses ATP to phosphorylate myosin cross-bridges, which bind to actin filaments, resulting in contraction. 3: Which of the following statements is true concerning calcium ions?

Increased cytosolic calcium restored the Cyt/Nuc ratio of TBPH significantly (p<0.05) in the PR100- and GR100-expressing larval motor neurons (Figure 7A right panels and 7B).
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 an intracellular 2nd messenger; it is involved in skeletal muscle contraction, excitation-contraction coupling in cardiac and smooth muscle, and activation of protein kinases and …
