Glycine and serine are connected in their breakdown. Write the mechanism of the breakdown of both glycine and serine (you don’t have to repeat all the steps that are the same for both) and explain where and how they are connected.

They both are connected at the serine hyrdoxylmethyl transferase as shown the diagram which initiates the brakdown of serine and glycine into tetrahydrofolate and N, N methylene THF.

Explanation:

See attached picture for structural information.

explanation:

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.
