Anton thinks that glucose is a reactant of photosynthesis, but his classmate Jamila disagrees. Who is correct, and why?
Answer
A
Anton is correct because glucose is a substance that is present before the chemical reaction of photosynthesis takes place.
B
Anton is correct because glucose is a substance that is formed from the chemical reaction of photosynthesis.
C
Jamila is correct because glucose is a product, not a reactant, of photosynthesis.
D
Jamila is correct because glucose is not involved in the chemical reaction of photosynthesis.
Explanation
Jamila is correct: photosynthesis uses carbon dioxide and water as reactants and produces glucose and oxygen. Glucose is formed during the reaction, so it is a product, not a reactant. Choice C states this correctly; glucose is involved in photosynthesis, so D is not correct.
