Biotechnology - Examples and fermentation

✓ Engaging presentation
✓ Worksheet with table and diagrams
✓ Lots of short AFL tasks
✓ Exam question on enzyme investigation

This lesson on Biotechnology is designed for KS4 Science students enrolled in the CIE Cambridge IGCSE Biology 0610 (2023-25) course. This is the second lesson in the topic 21 Biotechnology and Genetic Modification.

The lesson recaps previous learning from other linked topics to ensure students have a strong foundation before diving into the material. It also includes concise and easy-to-understand information and a variety of quick assessment for learning tasks to help students solidify their understanding of the topic. There is a strong emphasis on answering exam questions, with examples and the mark scheme included in the presentation.

Objectives:

• Describe the role of anaerobic respiration in yeast during the production of ethanol for biofuels
• Describe the role of anaerobic respiration in yeast during bread-making
• Describe the use of pectinase in fruit juice production
• Investigate and describe the use of biological washing powders that contain enzymes
• Explain the use of lactase to produce lactose-free milk
• Describe how fermenters can be used for the large-scale production of useful products by bacteria and fungi, including insulin, penicillin and mycoprotein
• Describe and explain the conditions that need to be controlled in a fermenter, including: temperature, pH, oxygen, nutrient supply and waste products

This lesson would also be adaptable for all GCSE students (whether AQA, Edexcel, OCR) and great for KS3 Science or as a GCSE revision resource.
