ATPase

Explanation: The sodium potassium pump is also known as ATPase.

This pump works by pumping potassium ions into the cell while pushing the sodium ions outside of the cell which is used to generate action potential across the cell membrane.

This pump performs active transport and the energy used for this process is derived from adenosine triphosphate. ATP is hydrolyzed and energy is energy is released which is used by this pump.

Hence, sodium potassium pump is known as sodium potassium ATPase.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
