Options

Choose one · Correct answer highlighted

Glucose-6-phosphate inhibits SPS-phosphatase Inorganic phosphate activates SPS-kinase Glucose-6-phosphate inhibits SPS-kinase Correct Inorganic phosphate activates SPS-phosphatase

Explanation

quantitative reasoning analysis shows ratio, percentage and series logic determine correct calculation. Consequently Glucose-6-phosphate inhibits SPS-kinase emerges as the valid choice since it meets mathematical and logical criteria, aligning with established principles in aptitude and reasoning literature.
