Compare and contrast aerobic and aerobic bacterial photosynthesis in terms of a) the source of electrons used by each; b) the final products of both reactions
What will be an ideal response?
The processes are similar in that both create carbohydrates, but differ in whether oxygen or some other molecule is the final product released. In aerobic photosynthesis, water is used as the electron and hydrogen source to make carbohydrates and oxygen. In contrast, anaerobic photosynthesis often utilizes hydrogen sulfide as an energy source to make carbohydrates, and sulfate, not oxygen, is released.
