5005 Praxis Practice Test Practice Question
Which of the following is a by-product of the process of photosynthesis?
Correct Answer: B
Rationale: Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, producing glucose and releasing molecular oxygen as a by-product.
Option A, ammonium nitrate, is a compound typically associated with nitrogen fixation, not photosynthesis. Option C, carbon dioxide, is a reactant in photosynthesis, used by plants to produce glucose and oxygen, rather than a by-product. Option D, sodium bicarbonate, does not play a role in photosynthesis and is unrelated to the process. Thus, molecular oxygen is the only correct by-product of photosynthesis.
