Multiple Choice
Which of the following best describes the role of ATP and NADPH in the process of photosynthesis?
A
ATP and NADPH are used to convert carbon dioxide into glucose during the Calvin cycle.
B
ATP and NADPH are stored as energy reserves in chloroplasts for cellular respiration.
C
ATP and NADPH are used to split water molecules during the light-dependent reactions.
D
ATP and NADPH are produced during the Calvin cycle to power the light-dependent reactions.
Verified step by step guidance
1
Understand the two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle (light-independent reactions).
Recognize that ATP and NADPH are produced during the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membranes of chloroplasts and involve the conversion of light energy into chemical energy.
Identify the role of ATP and NADPH in the Calvin cycle. These molecules provide the energy and reducing power needed to convert carbon dioxide (CO2) into glucose (C6H12O6) in the stroma of chloroplasts.
Clarify that ATP and NADPH are not stored as energy reserves in chloroplasts for cellular respiration. Instead, they are used immediately in the Calvin cycle to synthesize glucose.
Conclude that ATP and NADPH are not used to split water molecules during the light-dependent reactions; rather, water splitting is part of the process that generates these molecules.
