Challenge Problems
Push your limits with advanced challenges
Calculate the amount of ATP and NADPH required for six turns of the Calvin Cycle if each turn uses 1 ATP and 1 NADPH in the reduction phase.
💡 Hint: Remember the ratio of usage for each turn.
If a plant can fix CO₂ at a rate of 5 molecules per hour, how long will it take to produce one glucose molecule, knowing that six carbon dioxide molecules are needed?
💡 Hint: Use simple division to find the time per glucose production based on the fixation rate.
