Question

1. at the end of the electron transport chain, where is the light energy that was absorbed and converted by chlorophyll stored? list two answers.

Explanation:

In photosynthesis, after the electron transport chain (in the light - dependent reactions), the light energy absorbed by chlorophyll is used to generate ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules store the energy. ATP is a direct energy - carrying molecule, and NADPH carries energy - rich electrons that will be used in the Calvin cycle (light - independent reactions) to help convert carbon dioxide into glucose. Also, ultimately, the energy can be stored in the chemical bonds of glucose (a carbohydrate) that is produced in the light - independent reactions, as the energy from ATP and NADPH is used to fix carbon into glucose.

Answer:

1. In the chemical bonds of ATP (adenosine triphosphate).
2. In the chemical bonds of NADPH (nicotinamide adenine dinucleotide phosphate) (or in the chemical bonds of glucose, a carbohydrate, that is produced later in the photosynthetic process).
