Question

what is the product of the calvin cycle?

oxygen
water
carbon dioxide
glucose

Explanation:

Identify the question and diagram components

The question asks for the product of the Calvin cycle. The provided diagram shows a chloroplast where the light-dependent reactions occur on the left (thylakoids, labeled A and B) and the Calvin cycle occurs on the right (stroma, labeled C).

Analyze the inputs and outputs of the Calvin cycle

Using the Calvin Cycle Reactants and Photosynthesis Reactions knowledge points:

• The Calvin cycle (on the right) takes in carbon dioxide (\(\text{CO}_2\), labeled C) as an input.
• It uses energy carriers ATP and NADPH produced by the light-dependent reactions.
• The output pointing out of the bottom of the Calvin cycle is explicitly labeled "Sugars".

Match the diagram output to the multiple-choice options

The diagram shows "Sugars" leaving the Calvin cycle. Among the given choices:

• Oxygen is a product of the light reactions (photolysis of water at the thylakoid membrane).
• Water is a reactant in the light-dependent reactions.
• Carbon dioxide is a reactant for the Calvin cycle.
• Glucose is a simple sugar (monosaccharide) and represents the primary carbohydrate product of photosynthesis.

Answer:

• Oxygen
• Water
• Carbon Dioxide
• Glucose (Correct answer)
