Question

Quizplus · Accepted Answer

During oxygenic photosynthesis, water (H2O) is split to provide electrons, producing oxygen as a byproduct. In contrast, non-oxygenic photosynthesis, such as that performed by some bacteria, can use hydrogen sulfide (H2S) or other substances as electron donors, without producing oxygen.
