STUDY GUIDE
6.1 The Molecules of Living Systems
- describe the chemical structure and function of carbohydrates (simple sugar, polysacharides), lipids and proteins.
- explain how macromolecules are synthesized (dehydration synthesis) and how they are broken down (hydrolyzed)
- explain the function of enzymes, how they speed up chemical reactions and what factors affect enzyme action
- be able to explain the following diagrams from page 207-215
6.2 The Digestive System
- identify the main structures and functions of the digestive system (be able to label diagram)
- describe important secretions of the digestive tract (p.219, table 6.2)
- identify and describe the structure and functions of accessory organs (liver, gall bladder and pancreas)
- explain the chemical digestion and absorption of carbohydrates, lipids and proteins (be able to name each organ, enzyme secreted, substrate and product of digestion)
- describe where carbohydrates, lipids and proteins are absorbed
- describe how hormones (gastrin, secretin, CCK and GIP) regulate digestion function (p.230)
- describe the main function of the large intestine, bacteria in the colon, rectum and anus
6.3 Health and the Digestive System
- explain ulcers, inflammatory bowel disease, Crohn's disease, Colitis, Hepatitis A,B and C, Cirrhosis and gallstones
7.1 Structures of the Respiratory System
- identify the structures and functions of the upper and lower respiratory system
- describe the 4 stages of respiration (breathing, external respiration, internal respiration and cellular respiration)
7.2 Breathing and Respiration
- explain the mechanics of breathing (inhalation and exhalation)
- explain the purpose of a Spirograph and explain tidal volume, inspiratory reserve volume, expiratory reserve volume, vital capacity and residual volume
- explain gas exchange and external respiration
7.3 Respiratory Health
- identify and explain diseases that are associated with the respiratory system (tonsillitis, laryngitis, bronchitis, pneumonia, emphysema and asthma)
