Why is the term dark reactions considered misleading?
AIt implies the reactions produce no sugar
BIt implies the reactions need no enzymes
CIt implies the reactions occur outside cells
DIt implies the reactions run only at night
Answer & Solution
Correct answer: D. It implies the reactions run only at night
1. The most outdated name for these reactions is dark reactions, since light is not directly required.
2. That term can be misleading because it implies incorrectly that the reaction only occurs at night.
3. It also wrongly implies that the reaction is independent of light altogether.
4. Most scientists and instructors therefore no longer use it.
