While reading a biology resource text, a student noticed two terms used erroneously in the statement below:

Light energy is converted to chemical energy with the production of carrier molecules ATP and NADPH during the endergonic light-dependent reactions of photosynthesis.These carrier molecules provide the energy and reducing power for the synthesis of carbon-carbon bonds during the exergonic light-independent reactions of photosynthesis.

Which terms are used erroneously in the text?

Quizplus · Accepted Answer

The terms "endergonic" and "exergonic" are used erroneously. The light-dependent reactions of photosynthesis are actually exergonic because they release energy by converting light energy into chemical energy (ATP and NADPH). The light-independent reactions, which use the ATP and NADPH to synthesize carbon-carbon bonds, are endergonic because they require an input of energy.
