Ribonucleotide reductase controls the synthesis of deoxyribonucleotides and the balance of nucleotides in the cell. The R1 subunit of ribonucleotide reductase contains two allosteric sites, one that regulates the overall enzyme activity and another that regulates the substrate specificity of the enzyme.

Select the molecules that bind the site regulating overall ribonucleotide reductase activity.

A. GTP
B. GTP
C. МАТР
D. DATP

ATP and dATP

Explanation:

In the R1 subunit of ribonucleotide reductase, molecules that binds the site regulating overall ribonucleotide reductase activity  include both ATP and dATP. In addition, binding of ATP can activate ribonucleotide reductase and the binding of dATP deactivates ribonucleotide reductase.

the answer is d (apex) good luck : ))

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
