Question

what would happen to the concentrations of atp, nadph and sugars if the calvin cycle stopped working?
decrease stay the same increase
atp
nadph
sugars

Explanation:

Step1: Analyze ATP concentration change

The Calvin Cycle uses ATP to fuel its reactions. If it stops, ATP is no longer consumed, so its concentration builds up.

Step2: Analyze NADPH concentration change

NADPH provides electrons for the Calvin Cycle. Without the cycle running, NADPH is not used, so its concentration increases.

Step3: Analyze Sugar concentration change

Sugars are the end product of the Calvin Cycle. If the cycle stops, no new sugars are produced, so their concentration decreases as existing sugars are used.

Answer:

• ATP: Increase
• NADPH: Increase
• Sugars: Decrease
