From the Stage 2 SACE Biology course outline, this video discusses:
- Cell metabolism is critical to the survival of cells.
- Biochemical processes in the cell are influenced by the nature and arrangement of internal membranes and the presence of specific enzymes.
• Explain how the structure of internal membranes of mitochondria and chloroplasts facilitates some biochemical processes.
• Explain that in a metabolic pathway:
– there are many regulated steps
– each step loses some energy as heat
– some steps produce intermediate compounds
– specific enzymes are required at each step.
- Biochemical processes in the cell are influenced by environmental factors.
- Chemicals can interfere with cell metabolism.
• Discuss possible benefits and/or harmful effects of chemicals that human beings use.
