Read section 17-1, 17-2 and do the laboratory “The Importance of Light & Chlorophyll
for Photosynthesis” (lab. supplement to your book) and do answer the following questions
as a means of understanding this objective:

1. Define photosynthesis.(17-1)
2. State the general word equation for photosynthesis.(17-1)
3. Explain the importance of chlorophyll a to the photosynthetic process.(17-1)
4.   Explain the contributions made by chlorophyll b, carotenes, and xanthophylls to the
     photosynthetic process.(17-1)
5 Describe the structure and summarize the function of a chloroplast.(17-1)
6.   List the light reactions and the dark reactions as the two types of chemical reactions
     associated with photosynthesis, noting in general terms how the two types work together
     to produce glucose.(17-2)
7. List the environmental conditions that affect the rate of photosynthesis.(17-2)

1. Define metabolism. (p.8)
2.   Define cellular respiration and write a chemical equation to show its action. (p.86, 6-1, 6-
     3)
3    Explain why the chemical energy found in glucose needs to be converted into ATP for
     use by cells.(6-1)
4 Describe the role played by ATP in cells.(6-1)
5. Describe the role played by the mitochondrion in cellular respiration.(pp. 86-87)
6. State the sources of the glucose and oxygen needed for cellular respiration.(6-1, 6-2)
7. Define aerobic respiration and anaerobic respiration.(6-2)
8. Distinguish between aerobic and anaerobic respiration by noting differences in:
 i) the end products created,
 ii) the relative amounts of ATP produced, and,
 iii) the locations in the cell where each series of reactions occurs.(6-3)
 9.   Explain why both aerobic and anaerobic respiration are accompanied by a loss of energy
     as heat.(6-1, 6-3)
10.  Relate how both aerobic and anaerobic respiration have roles to play in the functioning
     of muscle cells in humans.(6-3)
11.  Explain how cellular respiration is related to the process of photosynthesis in the flow of
     energy and the cycling of matter.(p.347)
 

1.       Describe the organization and function of all structures in the human respiratory system.
         (11-2)
2.       Explain how the design of the human respiratory system is adapted to allow for efficient
         gas exchange by noting the functions of the following structures in human respiration:
 i) the cilia,
 ii) the mucus membranes,
 iii) the diaphragm and rib muscles,
 iv) the large surface area of the alveoli,
 v) the rings of cartilage in the trachea and bronchi,
 vi) the epiglottis.(p. 162, 11-2)
3. Describe the mechanics of ventilation.(11-2)
4. Explain how differences in air pressure cause the lungs to inflate and deflate.(11-2)
5. Explain how body can obtain oxygen and get rid of carbon dioxide.(11-2)
6. Explain how carbon monoxide poisoning occurs.(11-2)
7.Analyse the effects of smoking on the respiratory system by noting common disorders of
   the system (e.g. bronchitis, emphysema, lung cancer) that are caused or compounded by
    smoking.(11-2) 
8. Evaluate the trend to make certain public buildings smoke free.(11-2)
