How many carbon atoms combine in the photosynthesis reaction?(1 point) Responses 1 1 6 6 12 12 2

Answer 1

In the photosynthesis reaction, specifically the balanced equation for photosynthesis, six carbon dioxide (CO₂) molecules combine with six water (H₂O) molecules to produce one glucose (C₆H₁₂O₆) molecule and six oxygen (O₂) molecules. Therefore, the number of carbon atoms that ultimately combines to form one glucose molecule is 6.

So, the correct response is 6.
