A defective Na+/K+ ATPase pump is isolated from a plasma membrane and studied. Careful measurements in the laboratory determine
Paul [167]

Answer:

The defective Na+/K+ ATPase is not able to dephosphorylate itself.

Explanation:

Na+/K+ ATPase pump cycles between two different forms: the phosphorylated form of the Na+/K+ ATPase has a high affinity for K+ ions and low affinity for Na+ ions. The release of phosphate from ATP and phosphorylation of Na+/K+ ATPase makes the pump to release the bound 3 Na+ ions outside the cell and to bind to the 2 K+ ions from the surroundings. As the Na+/K+ ATPase is dephosphorylated, its affinity for K+ ions is reduced leading to the release of K+ inside the cell.  

A defective Na+/K+ ATPase that is able to pick and bind the K+ ions but is not able to shuttle them across the membrane should be defective to achieve its dephosphorylated form. Without releasing phosphate, the affinity of the pump for K+ ions is not reduced and the pump would not be able to release them to the opposite side of the membrane.

A piece of steel has a mass of 1170g and a volume of 150 cm3. What is the density of<br> steel?*
julsineya [31]

Answer:

<h3>The answer is 7.80 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of metal = 1170 g

volume = 150 cm³

We have

density  =  \frac{1170}{150}  =  \frac{117}{15}   =  \frac{39}{5}  \\

We have the final answer as

<h3>7.80 g/cm³</h3>

Hope this helps you
