Based on the map above, the step of photosynthesis that generates glucose sugar is…

• A. the Calvin cycle.
• B. the light reactions.
• C. C3 photorespiration.
• D. C4 photorestoration.

Answer: (A)

Verified step by step guidance

1. Understand that photosynthesis consists of two main stages: the light reactions and the Calvin cycle.
2. Recognize that the light reactions occur in the thylakoid membranes of the chloroplasts and are responsible for converting light energy into chemical energy in the form of ATP and NADPH.
3. Identify that the Calvin cycle, also known as the light-independent reactions or dark reactions, takes place in the stroma of the chloroplasts.
4. Learn that during the Calvin cycle, ATP and NADPH produced in the light reactions are used to convert carbon dioxide into glucose sugar through a series of reactions.
5. Conclude that the step of photosynthesis that generates glucose sugar is the Calvin cycle, as it involves the fixation of carbon dioxide into organic molecules, ultimately forming glucose.
