e. None of the above Textbook Reference: 8.1 What is Photosynthesis? p. 162 6. When a suspension of algae is incubated in a flask in the presence of light and CO 2 and then transferred to the dark, the reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate is blocked. This reaction stops when the algae are placed in the dark because a. the reaction requires CO 2 . b. the reaction is exergonic. c. the reaction requires ATP and NADPH + H + . d. the reaction requires O 2 . e. chlorophyll is not synthesized in the dark. Textbook Reference: 8.1 What Is Photosynthesis? p. 162 7.

Textbook Reference: 8.2 How Does Photosynthesis Convert Light Energy into Chemical Energy? p. 163 8. When white light strikes a blue pigment, blue light is a. reduced. b. absorbed. c. converted to chemical energy. d. scattered or transmitted.
