 Below is everything the examiners think you know, if you're not sure of something click on the link to watch my YouTube video explanation. For a copy of these you can print off, get the FREE revision guide I wrote for you.


 • I can describe the role of yeast in food production, including bread making

 • I can describe an experiment into the anaerobic respiration of yeast

 • I can describe the role of Lactobacillus bacteria in making yoghurt

 • I can describe the use of an industrial fermenter

 • I can describe the conditions needed within an industrial fermenter

 • I can describe how to clean and sterilise an industrial fermenter

 • I can state that restriction enzyme is used to cut genetic material and that ligase enzyme is used to join pieces of DNA together

 • I can state that bacterial plasmids and viruses are used as vectors and describe how this works

 • I can describe how insulin-creating bacteria are produced through genetic modification

 • I can describe how insulin is manufactured in an industrial fermenter

 • I can describe how genetically modified plants can be used to improve food production

 • I can define the term transgenic organism

 • I can describe how cloned transgenic animals are used to make human proteins
