Biology
1 answer:
Illusion [34]3 years ago
6 0
Prokaryotes have a significant role in decomposition of organic matter, bringing back key nutrients into the trophic network. By decomposing dead plant or animal parts, they enable the circulation of elements like phosphorus and sodium.
On the other hand, specialized bacteria have a role in transforming nitrogen compounds in the soil, converting them into chemical forms that are suitable for other organisms to use.

The sodium-potassium pump does not do which of the following actions?
Rzqust [24]

The sodium-potassium pump does not allow the movement of sodium molecules against their concentration gradient into the cell  with the use of ATP molecules.

In sodium-potassium pump, the sodium moves outside the cell whereas potassium moves inside the cell with the help of using ATP molecules. The sodium-potassium pump maintains the gradient of higher concentration of sodium extracellularly means outside the cell and a higher level of potassium intracellularly means inside the cell. This process is done only in the presence of ATP molecules that provides a force for the movement of sodium and potassium so we can conclude that no movement of sodium occur inside the cell in the sodium-potassium pump.
