To form NADPH in Photosystem I, the required reactants are two electrons and a hydrogen ion. Therefore, the correct response is:

two electrons and two hydrogen ions.

Suppose you seal a house plant in a transparent glass container. What about the scenario would lead to the plant’s death?(1 point)

In the scenario of sealing a house plant in a transparent glass container, the most likely reason that would lead to the plant’s death is a lack of carbon dioxide. Plants require carbon dioxide for photosynthesis, and while they will initially use the carbon dioxide in the sealed environment, this will eventually be depleted, leading to the plant's inability to produce the sugars it needs for energy.

However, if you're specifically focusing on the direct cause of death related to photosynthesis, the answer is more nuanced, as the plant will also suffer from a lack of nutrients over time. But, in the context of photosynthesis and gas exchange in this scenario, the lack of carbon dioxide is critical.
