Two proteins in the same cell perform di erent functions. This is because the two proteins are composed of

Two proteins that are present inside the same cell perform different functions because both proteins have different amino acid composition.

Explanation:

Amino acid is the building blocks of protein. Different proteins perform different functions due to their composition. These proteins are formed by the instructions given to the ribosome of the cell.

a time line cause it goes from 685 to 978

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.
