Step 1
Identify what V, W, and Z represent
Answer
To determine what V, W, and Z represent, we need to examine their roles in the context of photosynthesis and the associated biochemical processes.
Typically, in photosynthesis:
- V usually represents a reactant or product like carbon dioxide (CO₂).
- W can be associated with energy carriers like ADP or ATP.
- Z often represents coenzymes or electron carriers such as NADPH.
Based on common definitions, option C states: oxygen, ADP and NADPH. However, ADP is typically not produced directly from photosynthesis, making option C plausible but not completely valid. The presence of ADP suggests a cycle that involves energy transformation rather than direct photosynthesis.
In contrast, examining option D indicates:
- V as carbon dioxide
- W as ADP
- Z as NADP+, all of which suggest involvement in photosynthetic usage.
Thus, since the expected process depicts carbon dioxide as a prime reactant, the correct answer derived from the observed schema is D.
