Which of the following in NOT a step in the light-dependent reactions? ATP and NADPH are used to produce high-energy sugars
What are the products of the light reactions? ATP and NADPH and O2
What are the 3 products when water molecules are split during the light reactions? H+, e-, and O2
The light- independent reactions of photosynthesis are also known as the .. Calvin Cycle
The leaves of a plant appear green because chlorophyll.. Reflects green light.
The Dark Reactions cannot occur in the sunlight. True/False False
