In heart, spontaneous local increases in cytosolic Ca2+ concentration ([Ca2+]i) called "Ca2+ sparks" may be fundamental events underlying both excitation-contraction coupling and resting Ca2+ leak from the sarcoplasmic reticulum (SR). In this study, resting Ca2+ sparks were analyzed in rabbit an...

解答解:A.钙元素的原子序数为20,核外有20个电子,分四层排布,所以钙元素位于元素周期表的第4周期,故正确; B.钙原子的最外层有2个电子,在化学反应中易失去最外层的2个电子而带上2个单位的正电荷,离子符号为Ca2+,故错误; C.钙元素属于人体所需的常量元素,在人体中的含量为1.5%,故错误; ...
Mfn2 expression is reduced in H/R-treated NRK-52E cells and renal tissue of I/R rats. At the cellular level, overexpression of Mfn2 promoted cell proliferation, inhibited cell apoptosis, attenuated mitochondrial damage and Ca2+ overload, and ER stress. In addition, Mfn2 also restored the ...
解:钠离子是钠原子失去一个电子而得,带一个正电荷,故不用标钠离子的最外层的10个电子,用离子符号表示即可,故钠离子的电子式为:Na+;同理,金属阳离子均可用离子符号表示其电子式,故镁离子的电子式为Mg2+,钙离子的电子式为Ca2+;氧负离子是氧原子得到两个电子,最外层有8个电子,带有两个负电荷,故氧离子...

4I). This suggests that these peaks correspond to the same residues in the FGF12ACaMBDp and FGF12ANTD and that they have an essentially identical local chemical environment when bound by (Ca2+)4-CaM. That supports a model where (Ca2+)4-CaM is anchored to the FGF12ANTD via the CaMBD...
