A, plant with no fertilizer
Atomic #= 16
Mass=32.06
Neutrons=16 (subtract the atomic number by the mass(32-16=16))
Non metal
Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
