What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plas
marusya05 [52]

Answer:

The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.

Explanation:

Na+/K+ ATPase exists in two forms: Its phosphorylated form has a high affinity for K+ and low affinity for Na+. ATP hydrolysis and phosphorylation of the Na+/K+ pump favor the release of Na+ outside the cell and binding of K+ ions from the outside of the cell. Dephosphorylation of the pump increases its affinity for Na+ and reduces that for K+ ions resulting in the release of K+ ions inside the cells and binding to the Na+ from the cells.  

The presence of ATP analog would not allow the pump to obtain its phosphorylated form. Therefore, Na+ ions would not be released outside the cells. This would increase the Na+ concentration inside the cell above the normal. Similarly, the pump would not be able to pick the K+ from the outside of the cell resulting in reduced cellular K+ concentration below the normal range.

Name a difference between a vein and artery
Yuki888 [10]
Arteries like veins, are tube-shaped vessels that carry blood in the body. 
But the difference is that the artery carries oxygenated blood away from the heart to the body. But the veins carry poor-oxygen blood back from the body to the heart! 
I hope this helps! :)
