HW: Bring in Science Board Wednesday or
  Monday!
Cell       • Glucose (sugar) is broken
Respiration down to make ENERGY
             (ATP)
           • Occurs in mitochondria
           • Carried out by every
             living thing!!!
Aerobic    • Oxygen (O2) required
Respiration to make energy
Oxygen   Carbon dioxide
         & water vapor
              EQUATION
 C6H12O6 + 6O2 à 6CO2 + 6H2O +
 36ATP + OXYGEN à CARBON + WATER + ENERGY
GLUCOSE
                  DIOXIDE




  Raw materials
                            Products
Anaerobic • Energy produced
Respiration WITHOUT oxygen
           • FERMENTATION
           • Occurs in the cytoplasm
            EQUATION
 C6H12O6 à 6CO2 + 2ATP
  GLUCOSE       à CARBON       +       ENERGY
                  DIOXIDE
Raw materials
                            Products
Aerobic respiration




Anaerobic respiration
2 types of 1. ALCOHOLIC
 anaerobic   FERMENTATION =
respiration   – In yeast cells
• C6H12O6àalcohol + CO2+2ATP
2. LACTIC ACID FERMENTATION =
  – In your muscles, when oxygen is
    not available
• C6H12O6 à lactic acid + 2ATP
Let’s summarize…

•   Explain why the process of respiration is so
    important.
•   Explain the difference between the two types
    of respiration.
•   What nutrient is used in both types of
    respiration?
•   Which type of respiration is more efficient?
Review:
• Yeast cells undergoing anaerobic
  respiration produce carbon dioxide
  and                                                             
  (1.) water  
  (2.) ethyl alcohol  
  (3.) nitrogen  
  (4.) glucose 
2. During the process of respiration, energy
  from the oxidation of glucose is stored in
  molecules of
(1.) DNA     
(2.) ADP     
(3.) ATP     
(4.) RNA
3. In the presence of oxygen, _____
  molecules of ATP can be formed. 
(1.)2      
(2.) 19        
(3.) 36          
(4.) 63
4. Which process yields lactic acid
 and small amounts of usable
 energy?                                                
 (1.) photosynthesis        
 (2.) aerobic respiration                         
 (3.) anaerobic respiration    
 (4.) chemosynthesis
5. The net yield of ATP from the
 process of fermentation is
 (1.) 2     
 (2.) 4      
 (3.) 34     
 (4.) 36
6. Muscles cells engaged in vigorous
 activity build up relatively high
 concentrations of
 (1.) lactic acid 
 (2.) pyruvic acid 
 (3.) alcohol 
 (4.) oxygen 
7. Where do the final stages of cellular
  respiration appear to take place?         
  (1.) along the endoplasmic reticulum 
  (2.) in the cytoplasm                                 
  (3.) on the surface of ribosomes 
  (4.) within the mitochondria
8. Aerobic respiration and
  fermentation are similar in that
  BOTH processes                                     
  (1.) require oxygen 
  (2.) use light energy                                  
  (3.) release energy 
  (4.) produce glucose
9. During aerobic respiration, the
  chemical energy of a glucose molecule
  is gradually released, producing 36
  ATP and
(1.) NH3 and O2           
(2.) NH3 and CO2            
(3.) H2O and O2
(4.) H20 and CO2
Review:
Which statement is not a part of the cell
  theory?
(1) Cells are the basic unit of structure of 
  living things.
(2) Cells are the basic unit of function of 
  living things.
(3) Cell parts such as chloroplasts are self-
  replicating.
(4) Cells come from preexisting cells.
Which structure permits the entry
   and exit of materials in an animal
   cell?
1. lysosome     2. chromosome               
3. cell wall       4. cell membrane
The structure most closely
   associated with the destruction of
   worn out cell organelles is the
• lysosome      2. centrosome
3.  vacuole        4. chromosome
Whitney observes a cell under the
 microscope. She identifies it as a
 green plant cell and not a cheek cell
 because of a
 (1.) nucleus      
 (2.) cell membrane 
 (3.) cell wall    
 (4.) mitochondrion
Which structure is found ONLY
   in animal cells?
(1.) cell wall
(2.) vacuoles
(3.) centrioles
(4.) chloroplasts
The organelle most closely
   associated with the manufacture
   of proteins within the cell is the
(1.) ribosome
