ATP can be used to activate a substrate by
A)phosphorylation.
B)adding a nucleotidyl group.
C)producing inorganic phosphate.
D)Both A and B.

Question

Quizplus · Accepted Answer

ATP can activate a substrate by phosphorylation or by adding a nucleotidyl group. The phosphate group or nucleotidyl group can increase the energy level of the substrate and make it more reactive. Therefore, choices A and B are both correct. The production of inorganic phosphate is a result of ATP hydrolysis and does not directly involve substrate activation.
