5. P2 The need for food. Discuss why we need it. expts- blow custard powder over a candle flame Deflagrating spoon burning food, heating up test tube of water with a thermometer NOT peanut Discuss heat losses in design of experiment- how to improve it? P3 Body building- need approx 0.6g protein per kg body weight. Need bathroom scales, calculate intake. Summarise paragraph info: Protein needed for building new cells inc muscle, bone. Too little reduces growth. High protein foods Milk, eggs, meat. Recommend 0.6g per kg body weight. Disease Kwashiorkor if too little protein and high carbohydrate- swollen stomach, muscles waste away.P2 The need for food.

Learning outcome Describe the role of different types of teeth in the mechanical breakdown of food in a herbivore, carnivore and an omnivore such as a human Learning outcome Describe the role of different types of teeth in the mechanical breakdown of food in a herbivore, carnivore and an omnivore such as a human

21. Ingestion Food is taken into the mouth and mechanically broken down and crushed by the teeth. Digestion Large insoluble molecules are broken down into smaller soluble molecules by the action of digestive enzymes. Hydrolysis reactions. Absorption Products of digestion are absorbed through the gut wall. Egestion Elimination of undigested food, dead cells and bacteria as faeces.

26. Stomach P15 stomach Sac with sphincters at each end to control entry and exit of food to and from stomach. Cardiac sphincter (entry), Pyloric sphincter Contracts – keeps food in stomach Relaxes – allows chyme to pass into small intestine Digestion in stomach gastric juice – mostly water, with HCL Absorption in stomach None major nutrients absorbed through walls Small lipid soluble molecules pass easily, e.g. aspirin and alcoholP15 stomach Sac with sphincters at each end to control entry and exit of food to and from stomach.
