Question

where are the raw materials for the calvin cycle primarily obtained? from redox of oxygen from the light reactions from the krebs cycle

Explanation:

The Calvin - cycle is part of photosynthesis. The raw materials for the Calvin cycle, ATP and NADPH, are primarily obtained from the light - reactions of photosynthesis. Oxygen reduction is related to cellular respiration, not the main source of Calvin - cycle raw materials. The Krebs cycle is also part of cellular respiration.

Answer:

From the light reactions
