Archeoglobus, one of these types of cyanobacteria, uses the pathway shown in the chemical equation. 4H2 + SO42− + 2H+ → H2S + 4H2O Based on this equation, which explanation best describes how the process of chemosynthesis in bacteria differs from photosynthesis, and why can this process occur in the absence of oxygen? Chemosynthesis uses H2 as an energy source, while photosynthesis uses the Sun as an energy source. Chemosynthesis uses H+ as an energy source, while photosynthesis uses the Sun as an energy source. Chemosynthesis reduces a sulfate molecule in the absence of oxygen and light, while photosynthesis depends on light to reduce carbon dioxide. Chemosynthesis oxidizes a sulfate molecule in the absence of oxygen and light, while photosynthesis depends on light to reduce carbon dioxide.
