Cyanobacteria are chemosynthetic organisms that reside deep in the ocean near hydrothermal vents. 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.

Fill in the products for each of the following reactions.
BACKGROUND Oxidation numbers can be assigned to determine if an atom is reduced or oxidized during the course of a reaction. An organic compound that has a carbon atom that has been reduced has generally obtained more hydrogen atoms. Hydrogen is less electronegative than carbon, so bonds to additional hydrogen atoms increase the electron density around a carbon atom. In contrast, when oxidation occurs in an organic molecule, a carbon atom loses H atoms, or forms additional bonds to more electronegative elements such as oxygen or nitrogen. One of the most commonly used methods for the preparation of 1° and 2° alcohols is via the reduction of aldehydes or ketones. In the generic reactions shown below, [H] represents the reducing agent, the reactant that causes reduction of the organic molecule. The conversion of a carbonyl compound to an aldehyde can be recognized as a reduction reaction because the carbonyl carbon forms an additional bond to a less electronegative H atom,…
