Where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?

Question

Responses

They obtain the energy directly from the Sun.
They obtain the energy directly from the Sun.

They convert the 6-carbon sugars into 5-carbon sugars.
They convert the 6-carbon sugars into 5-carbon sugars.

They use the ATP and NADPH that are produced during the light-dependent reactions.
They use the ATP and NADPH that are produced during the light-dependent reactions.

They use the ADP and carbon dioxide produced during the light-dependent reactions.

Answer 1

The correct response is:

They use the ATP and NADPH that are produced during the light-dependent reactions.

During the light-independent reactions (or Calvin cycle) of photosynthesis, organisms utilize the energy stored in ATP and the reducing power of NADPH, which are generated during the light-dependent reactions, to convert carbon dioxide into sugars.
