Chapter 5 Study Guide
1. Define and Write the Equation for the following processes. CIRCLE the reactants (requirements) and BOX the
products.
A) Photosynthesis
6CO2 + 6H2O + Sunlight -> 6O2 + C6H12O6
B) Cellular Respiration
C6H12O6 + 6O6 -> 6H2O + 6CO2 + ATP
2. Summarize the three stages of photosynthesis.
A) Stage 1
Light Dependent: Chloroplast absorbs light energy through the pigment called chlorophyll. The light energy excited
electrons
B) Stage 2
Light Dependent: The excited electrons jump in the thylakoid. Water is split to replaced lost electrons. The by-product
oxygen is created in this stage.
C) Stage 3
Light Independent: The Calvin Cycle creates Glucose to be used for the plant.
3. Describe what happens in Cellular Respiration after the process of glycolysis in the presence and absence of O2.
A) Presence of Oxygen:
Pyruvates created from glycolysis are used to undergo aerobic respiration in the Krebs cycle. The Krebs’s cycle occurs in
the mitochondria and creates the by-product carbon dioxide, and ATP.
B) No Oxygen is present:
Will undergo Fermentation: lactic acid or alcoholic. Products are Alcohol, lactate, and CO2
4. Draw a simple diagram the shows the energy cycle using the SUN, a heterotroph, and an autotroph. Write a
sentence that explains the importance of the SUN.
Sun -> Plant (autotroph) -> Animal (Heterotroph)
The sun provided energy for autotrophs to create glucose through photosynthesis. The heterotrophs than use the plants
as food energy to break down glucose and use to create ATP.
5. Using Page 110 in your text box complete a diagram like the one shown as Figure 16.

6. Draw a plant. Label the requirements being used by the plant for photosynthesis, and the products being
created by the plant.
