Question

a student creates a 2 - d model showing the conversion of light energy into chemical energy in a chloroplast. the teacher tells the student that something is incorrect in the model. what should the student change to make the model scientifically correct? exchange the positions of the light - dependent and light - independent reactions. exchange the positions of oxygen and water in the light - dependent reaction. move the carbon dioxide to the other side of the light - independent reaction. move the atp and nadph below the light - independent reaction.

Explanation:

In the light - dependent reactions of photosynthesis in a chloroplast, water is split to release oxygen. So oxygen should be a product and water a reactant in the light - dependent reactions. Currently, they seem to be in the wrong positions in the model.

Answer:

B. Exchange the positions of oxygen and water in the light - dependent reaction.
