Answer:

Mg most commonly forms a 2+ ion. This is because Mg has two valence electrons and it would like to get rid of those two ions to obey the octet rule. Fluorine has seven valence electrons and usually forms the F – ion because it gains one electron to satisfy the octet rule.

Which of the pathways for nucleotide biosynthesis builds the base ring on a PRPP molecule?

Pepsi [2]

Answer:

A) purine

Explanation:

There are two ways for the synthesis of purines and pyrimidines:

de novo synthesis-from basic simple units

"recycling" synthesis-reuse of metabolites

Purines are synthesized directly on ribose sugar, in segments.

Pyrimidines are attached to the ribose after the synthesis of the base.

5-Phosphoribosyl-1-pyrophosphate (PRPP). is used for the synthesis of purine (ribose 5-phosphate reacts with ATP to form ribonucleotide).
