Answer:

2, 2, 1

Explanation:

The coefficient of H₂O will be 2 because we have 2 oxygens on the right side but only one on the left side. Now, we have 4 hydrogens on the left side but only 2 on the right side. To balance, we'll add a 2 as the coefficient of H₂. We don't need to change the coefficient of O₂ because the equation is already balanced.

Final answer, 2, 2, 1.

Aloiza [94]

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.
