Question 4 • CMS 2026-2027 Biology CREDIT RECOVERY
Cellular respiration proceeds through glycolysis first, where glucose is split in the cytoplasm. The products then enter the Krebs cycle, followed by the electron transport chain, which produces most of the ATP. Therefore, the correct order is “glycolysis → Krebs cycle → electron transport chain.” The Calvin cycle belongs to photosynthesis, not cellular respiration.
