The model shows a chloroplast during photosynthesis.

A box labeled Energy has a question mark inside. An arrow points from this box to a thylakoid inside the chloroplast. A box labeled Reaction 1 has the word Water inside. An arrow points from this box to the thylakoid. A line extending from the thylakoid points to a box labeled Product 1 with the word Oxygen inside. Two arrows point from the thylakoid to a circle with arrows on it. An arrow points from a box labeled Reaction 2 with the word Carbon Dioxide in it to the circle with arrows on it. A line extending from the circle with arrows on it to a box labeled Product 2 with a question mark inside. Two arrows point from the circle with arrows on it to the thylakoid.

Which pair of questions can be asked to complete the labeling of the model?

A.
What is the source of energy in the Krebs cycle, and what is the product of glycolysis?

B.
What is the source of energy in glycolysis, and what is the product of light reactions?

C.
What is the source of energy in light reactions, and what is the product of the Calvin cycle?

D.
What is the source of energy in the Calvin cycle, and what is the product of the Krebs cycle?

C.

The thylakoid (light reactions) uses light (sunlight) as the energy source, and the Calvin cycle (the CO2-fixation reactions) produces carbohydrates (e.g., glucose/G3P).
