Answer:
Decrease in ATP concentration be larger.
Explanation:
Decrease in ATP concentration be larger because 2-deoxyglucose poison inhibit glycolysis. Glycolysis is the first step of energy production where glucose break down started and two ATP are produced. If the first step of ATP production is stopped, no energy will be produced so we can conclude that 2-deoxyglucose poison causes larger decrease in ATP concentration.
