Role of yeast in beer production: Fermentation is anaerobic respiration by yeast (fungus) Glucose → ethanol + carbon dioxide
Process: Barley seeds are germinated (warm, moist) Seeds make amylase which converts: starch → maltose (sugar) Yeast is added to ferment the sugars to produce alcohol Hops are added for flavour
you could add a bit more in on this bit such as

Yea all good... Except none of it is required in the syllabus for this particular statement.
