Question

Which process occurs last in the Calvin cycle/photosynthesis?

Question 1 options:

splitting of water


carbon fixation


formation of an "excited" electron


formation of NADPH

Answer 1

In the Calvin cycle, the processes occur in a specific order. The last process to occur in the Calvin cycle (which is part of photosynthesis) is carbon fixation, where carbon dioxide is fixed into an organic molecule.

However, if we focus on the overall photosynthesis process and consider the light-dependent reactions, the formation of NADPH occurs last in that stage.

So, if the question is specifically about the Calvin cycle, the answer would be **carbon fixation**. If it's more broadly about photosynthesis including light-dependent reactions, then the answer could be **formation of NADPH**.
