What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plas
Gennadij [26K]

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

<h3><u>Explanation</u>:</h3>

The membranes that contain high concentration of sodium potassium ATPase pumps are generally the excitable membranes. These are found in muscles and in neurons.

In normal scenario, the de polarised membrane has higher potassium concentration inside and higher sodium concentration outside it. Now as an impulse comes, the sodium channels open which creates sodium influx and then potassium channels open which let's potassium efflux. Then after the conduction of impulse is over, the membrane regains its de polarised state by the sodium potassium ATPase pumps which transfers three potassium outside the cell and two potassium inside the cell in exchange of an ATP.

Now if the ATP is non hydrolyzable, then the pump won't occur. This will lead to greater sodium inside the cell and greater potassium outside the cell but the change difference will be nil on both sides.

Salsk061 [2.6K]

Answer:

Type II restriction enzymes are the familiar ones used for everyday molecular biology applications such as gene cloning and DNA fragmentation and analysis. These enzymes cleave DNA at fixed positions with respect to their recognition sequence, creating reproducible fragments and distinct gel electrophoresis patterns. Over 3,500 Type II enzymes have been discovered and characterized, recognizing some 350 different DNA sequences. Thousands more ‘putative’ Type II enzymes have been identified by analysis of sequenced bacterial and archaeal genomes, but remain uncharacterized.

Explanation:

I hope this is right I need a brainlest.
