Question 5

An early experiment by Van Helmont (1600s)  describes how he "grew a tree in a large pot and found that after five years, the amount of soil in the pot had not changed. He concluded that the increase in weight was due to the addition of water." At that time, the compounds in the air had not yet been identified. Today, you know that he only discovered half the story. Which additional experiment would provide evidence for the rest of the story?

Question 9

Characterize the reactions involved in these reactions of the Calvin Cycle. 2. Energy is required in the form of ATP, which is hydrolyzed to ADP. The substrate BPG is reduced, while the coenzyme NADPH is oxidized. C)  These reactions are involved in the fixation of CO2. Energy is required in the form of ADP, which is hydrolyzed to ATP. The substrate BPG is oxidized, while the coenzyme NADPH is reduced. D)  These reactions are part of Light Reactions in noncyclic pathway. ATP and NADPH are used during these reactions.

Question 12

The action spectrum of photosynthesis shows a high light absorption for violet/blue and orange/red and a low absorption for green/yellow.
