AQA A-level Biology (2016 specification). Section 3 Topic 6 Exchange. 9 Enzymes and digestion

Lengthy PowerPoint detailing enzymes and digestion, designed to completement the bespoke class notes for this topic, available separately on TES. It starts off by labelling the major parts of the digestive system, but then students are expected to use the spec to identify the parts they actually need to learn(!). There is an activity - 'guess the parts of the digestive system' and then physical breakdown and chemical digestion are outlined. There's a quick bit of carbohydrate revision before students are tasked to arrange the cards so they detail starch digestion in mouth and illeum. The PPT then moves on to protein digestion, before the processes that lead to amino acid absorption via the co-transport mechanism are considered. There are links to previously taught year 1 material (movement across membranes). The PPT contains notes with most of the answers to the questions on the PPT, but also some answers to the activities in the class notes about lactose intolerance a table which students complete, using the information covered in the lesson - it's quite challenging for them!
