• plants

• tube worms
• cyanobacteria
• chemoautotrophic bacteria

Production of ATP occurs in all of the following processes EXCEPT

• glycolysis
• Krebs cycle
• light independent reactions of photosynthesis
• light dependent reactions of photosynthesis

Which of the following occurs in both fermentation and aerobic cellular respiration
