1. THE CELL<br />

This section looks at life in terms of the cell. Knowledge of eukaryotic and prokaryotic cellular structure and<br />

the processes which take place in all living cells is fundamental to explaining how life ‘works’. Cell biology<br />

also has medical and commercial applications and these are also considered in this section.<br />

These questions may be put to candidates to stimulate discussion and prompt and direct their own<br />

researches while covering Section 1.<br />

• What makes eukaryotes different from prokaryotes?<br />

• Are eukaryotes more successful than prokaryotes?<br />

• What are the advantages and disadvantages of using electron microscopes?<br />

• How can I determine what is inside a cell and what the parts do?<br />

• How are intracellular structures adapted to their functions?<br />

• How do cells replicate?<br />

• How are meiosis and genetics connected?<br />

• How and why do a variety of proteins catalyse such a variety of different reactions so specifically?<br />

• If enzymes denature at 55°C, how do organisms live in hydrothermal vents deep in the ocean or in hot<br />

springs at 95°C?<br />

• What is it about ATP that makes it so important?<br />

• How does ATP get made?<br />

• Why is anaerobic respiration so much less efficient at releasing energy from a glucose molecule than<br />

aerobic respiration?<br />

• What is the role of DNA?<br />

• How do organisms control their genes?<br />

• What is genetic engineering and is it a good thing or a bad thing?<br />

• How is knowledge and understanding of Biology applied to gene technology?<br />

• Selective breeding ...... is it genetic engineering or not?<br />

• How do I transfer a gene from one species to another, and how can I tell if I have done it successfully?<br />
