【答案】：钠-钾泵是指各种细胞的细胞膜上普遍存在着一种转运Na+、K+的特殊蛋白质。又由于具有水解ATP的能力，故又称为Na+-K+依赖式ATP酶。
5.钠钾泵(sodium potassium pump)又称钠泵或钠钾ATP酶,它会使细胞外的Na+浓度高于细胞内,当Na+顺着浓度差进入细胞时,会经
钠钾泵(Sodium-Potassium Pump)简称钠泵,即Na+,K+-ATP酶为细胞膜中存在的一种特殊蛋白质可以分解ATP获得能量,并利用此能量进行Na+、K+的主动转运,即能逆浓度梯度把Na+从细胞内转运到细胞外,把K+从细胞外转运入细胞内,ATP酶的主要作用是控制细胞膜内外的K+,Na+离子的浓度差,维持细胞内外液的渗透压。O网页链...
神经元细胞膜上的钠钾泵(Sodium-Potassium Pump)又称钠钾转运体,也是Na+,K+-ATP酶。它能分解ATP获得能量,并利用此能量进行Na+、K+的
6、维持细胞的渗透性，保持细胞的体积；7、维持低Na+高K+的细胞内环境，维持细胞的静息电位。钠钾泵（sodium potassium pump）又称钠泵或钠钾ATP酶，它会使细胞外的Na+浓度高于细胞内，当Na+顺着浓度差进入细胞时，会经由本体蛋白质的运载体将不易通过细胞膜的物质以共同运输的方式带入细胞。
钠钾泵(sodium potassium pump)又称钠泵或钠钾ATP酶,它会使细胞外的Na+浓度高于细胞内,当Na+顺着浓度差进入细胞时,会经由本体蛋白质的运载体将不易通过细胞膜的物质以共同运输的方式带入细胞.下列相关叙述错误的是( ) A.通过该转运蛋白转运钠钾离子的方式为主动转运 ...
B. Steinbach in 1940 (see ref. 20), Dean concluded: " the muscle can actively move potassium and sodium against concentration gradients... this requires work. Therefore there must be some sort of a pump possibly located in the fiber membrane, which can pump out the sodium or, what is ...
The sodium-potassium pump, also referred to as Na,K-ATPase, is involved in active transport. This process requires energy to move the sodium and potassium ions into and out of the cell. Adenosine triphosphate, or ATP, is the high-energy carrying molecule that is the primary source of this...
1. The activity of ouabain-sensitive Na,K-dependent ATPase and ouabain-sensitive ATPase was measured in the microsomal fractions of kidney, liver and heart tissue of Sprague-Dawley rats treated with DOCA (10 mg day kg for 6 days, systolic blood pressure 143 ± 13 mmHg, n = 9) or 6 α...
