(A) Cornelius Van Niel,based on his studies of purple and green sulfur bacteria,demonstrated that photosynthesis is essentially a light-dependent reaction in which hydrogen from a suitable oxidizable compound reduces carbon dioxide to carbohydrates. He proposed that in green plants,water $(H_2O)$ acts as the hydrogen donor,releasing oxygen as a byproduct,whereas in sulfur bacteria,hydrogen sulfide $(H_2S)$ acts as the hydrogen donor.

The hypothesis that all photosynthetic organisms require a source of hydrogen was first proposed by
