• C, D and E only

• D and E only

• A, B and C only

• B, C and D only

Answer 1

C, D and E only

Explanation:

Three essential elements are needed for the dark processes of photosynthesis, sometimes referred to as the Calvin cycle or C₃ cycle: carbon dioxide (CO₂), ATP (adenosine triphosphate), and NADPH (nicotinamide adenine dinucleotide phosphate hydrogen). These chemicals are created in the thylakoid membranes of the chloroplasts during the light-dependent processes of photosynthesis. The energy contained in ATP and the reducing power of NADPH are used in the dark processes to fix CO₂ into organic molecules like glucose.
