The conversion of ribose-1-phosphate to ATP via the salvage pathway would require the activity of several enzymes.Choose the answer that lists them in the order that they would act in this pathway.
A) PRPP synthetase; phosphopentomutase; kinase; kinase; phosphoriboxyl transferase
B) PRPP synthetase; phosphoriboxyl transferase; phosphopentomutase; kinase; kinase
C) phosphopentomutase; PRPP synthetase; phosphoriboxyl transferase; kinase; kinase
D) phosphopentomutase; phosphoriboxyl transferase; kinase; PRPP synthetase; kinase

Question

Quizplus · Accepted Answer

Phosphopentomutase converts ribose-1-phosphate to ribose-5-phosphate, PRPP synthetase converts ribose-5-phosphate to PRPP, phosphoriboxyl transferase adds a base to PRPP, and kinases are involved in the phosphorylation steps to form ATP.
