Answer:
The photosynthesis process is interrupted.
Explanation:
Algae produce energy using the photosynthesis process. The reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate is part of this process. Despite this reduction reaction being light-independent (Calvin Cycle), the precursors of this reaction are synthesized in light-dependent steps.
This is the reason why the reduction is blocked when the algae is placed in the dark.
