Question

Which of the following would be a typical product of the dark reactions of photosynthesis?

a) ethanol
b) 3-phosphoglycerate acid (3-PGA)
c) green fluorescent protein
d) FADH2
e) pyruvate"

Answer 1

In the dark reactions of photosynthesis, or the Calvin cycle, the typical product is 3-phosphoglycerate acid (3-PGA), used to produce sugars.

Step-by-step explanation:

The typical product of the dark reactions of photosynthesis, also known as the Calvin cycle or light-independent reactions, is 3-phosphoglycerate (3-PGA).

During the Calvin cycle, atmospheric carbon dioxide is fixed and reduced to produce 3-PGA, which is then used to regenerate ribulose bisphosphate (RuBP) and to form sugars like glucose and other carbohydrates. Therefore, the correct answer from the options provided is (b) 3-phosphoglycerate acid (3-PGA).
