What is the role of ATP and NADPH in the Calvin cycle?
Correct Answer: ATP provides energy and NADPH provides reducing power for the Calvin cycle.
Step 1: Understand that the Calvin cycle is a process in plants that helps convert carbon dioxide into glucose (sugar).
Step 2: Know that ATP (adenosine triphosphate) is a molecule that stores and provides energy for many cellular processes.
Step 3: Realize that NADPH (nicotinamide adenine dinucleotide phosphate) is a molecule that carries electrons and provides reducing power, which helps in chemical reactions.
Step 4: In the Calvin cycle, ATP is used to supply the energy needed for the reactions to occur.
Step 5: At the same time, NADPH donates electrons to help convert carbon dioxide into glucose, making it easier for the plant to build sugar.
Step 6: Together, ATP and NADPH are essential for the Calvin cycle to produce glucose from carbon dioxide.
