Answer

Brief Explanations:

Autotrophic organisms, like plants, use the Calvin cycle (light - independent reactions of photosynthesis) to fix carbon dioxide and produce organic compounds. The Krebs cycle occurs in both autotrophs and heterotrophs (in cellular respiration). Chemiosmosis is involved in both photosynthesis (in chloroplasts) and cellular respiration (in mitochondria) in various organisms. The proton pump mechanism is a more general concept related to ion transport and is not exclusive to autotrophs.

Answer:

A. Calvin cycle
