Ethics of Performance Enhancement in Sports and Genetic Modification: Benefits and Dilemmas

Explore the ethical considerations of using growth factors in sports & advances in genetic modification in plants and animals. Discover the advantages for athletes taking growth factors, health risks of anabolic steroids, and why these substances are banned in sports. Dive into genetic modification impact, human safety, environmental implications, and ethical issues. Learn about gene therapy for diseases like Cystic Fibrosis, Cancer, and Hemophilia, and how it works. Delve into energy flow, photosynthesis, and human exploitation of plants as a food source.

Presentation Transcript

  1. B2 - Divide and Develop Finishing off B2 2.16 - Discuss the ethics and health concerns of using growth factors to enhance performance in sport B2 2.18 - Discuss the potential benefits and ethical dilemmas posed by advances in genetic modification in plants and animals

  2. What advantages are produced in an athlete taking growth factors? • What are the health risks of taking anabolic steriods? • Why are these substances banned from sport? What are the ethical arguments?

  3. What advantages are produced in an athlete taking growth factors? • Anabolic steroids are similar to the hormone testosterone. • The effects are similar to those seen in puberty changes .

  4. What are the health risks of taking anabolic steroids? • Side effects include: • Liver damage  failure • Facial hair growth (in ladies!) • Voice becomes deeper (in ladies!) • Impotence, shrinking testes, breast development (in gentlemen!) • Enlarged organs  heart.

  5. Why are these substances banned from sport? • What are the ethical arguments?

  6. Genetic modificationOrganism Genetic modification Purpose • For your organism explain using an A4 poster the impact of the modification. • Answer the following questions which you will present to the audience: • What are the implications for human safety? • What are the implications for the environment? • What are the ethical issues?

  7. Gene Therapy • Diseases with the capacity to be treated by gene therapy. • Cystic Fibrosis, Cancer & Haemophilia. • How can genes be introduced? • The use of viruses

  8. Gene therapies of cancer • Markers on cancerous cells • Stop or die genes activated in cancer cells • Sensitisation to drugs &/or radiation • Introduction of genes which dominate genes with a predisposition • To eradicate faulty genes would require

  9. Home work • http://gslc.genetics.utah.edu • Select: ‘Gene therapy: molecular bandage’ • ‘What is gene therapy?’ • ‘When a gene code is altered’ Write three sentences about what you learn Write three Qs which you cannot answer and need to research

  10. B2 Topic 3 - Energy Flow • B2 3.1 recall that plant and animal cells are similar because they contain nuclei, cytoplasm and membranes and that plant cells also have cellulose cell walls, chloroplasts containing chlorophyll and vacuoles. • B2 3.2 recall the reactants (carbon dioxide, water) for and products (glucose, oxygen) of photosynthesis. • B2 3.3 explore human exploitation of plants, including their use as a food source.
