D) through the pentose-phosphate pathway.
E) by beta-oxidation.

Question

Quizplus · Accepted Answer

Photophosphorylation captures energy from sunlight and uses it to produce ATP, which is then used to power the Calvin-Benson cycle. This cycle produces glucose from carbon dioxide in a process known as carbon fixation. The Krebs cycle, cyclic phosphorylation, pentose-phosphate pathway, and beta-oxidation are all involved in different metabolic processes and not directly related to the production of glucose through photophosphorylation.
