Daniel I. Arnon was the first to demonstrate the chemical function of photosynthesis outside of a plant cell, creating sugar and starch from carbon dioxide and water?
Question 1: ________, the enzyme that captures carbon dioxide in the light-independent reactions, has a binding affinity for both carbon dioxide and oxygen.
Question 4: The first photosynthetic organisms probably evolved about 3,500 million years ago, and used ________ or hydrogen sulfide as sources of electrons, rather than water.
Question 5: In plants, algae and cyanobacteria this is done by a sequence of reactions called the ________, but different sets of reactions are found in some bacteria, such as the reverse Krebs cycle in Chlorobium.
Question 7: The surface of the leaf is uniformly coated with a water-resistant waxycuticle that protects the leaf from excessive evaporation of water and decreases the absorption of ultraviolet or ________light to reduce heating.
Question 8: For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reaction centers that contain ________.
