Make Sure You Can:
1. Explain how chemoheterotrophic energy processing allows for the production of useful energy for organisms.
2. Explain why and how chemoheterotrophic energy processing is controlled.
3. Identify the reduction and oxidation reactions that occur in cellular respiration.
4. Explain the processes and identify all inputs and outputs of all steps of anaerobic and aerobic cellular
respiration.
5. Relate the different steps of chemoheterotrophic nutrition to their locations in the cell.
