AP BIOLOGY
Chapter 10
Objectives- By the end of this week you should be able to: (Many of these will be review from Honors
Biology. Objectives in bold are new or done in more detail.)
1. Distinguish between autotrophic and heterotrophic nutrition.
2. Distinguish between photoautotrophs and chemoautotrophs.
3. Describe the structure of chloroplasts, indicate their locations within plant cells, and explain how
their structure relates to their function.
4. Write a summary equation for photosynthesis.
5. Explain van Niel's hypothesis and explain how it contributed to our current understanding of
photosynthesis.
6. Explain the role of redox reactions in photosynthesis.
7. Describe in general the two main stages of photosynthesis.
8. Describe the wavelike and particle-like behaviors of light.
9. Distinguish between an action spectrum and an absorption spectrum.
10. Explain why the absorption spectrum for chlorophyll differs from the action spectrum for
photosynthesis.
11. Predict which wavelengths of light that would be most effective for photosynthesis in terms of
energy and absorption.
12. Explain what happens when chlorophyll or accessory pigments absorb photons.
13. List the components of a photosystem and explain their functions.
14. Trace electron flow through photosystems II and I.
15. Compare cyclic and noncyclic electron flow and explain the relationship between these
components of the light reactions.
16. Compare and contrast the processes of chemiosmosis in oxidative phosphorylation( in
mitochondria) and photophosphorylation (in chloroplasts).
17. Summarize the carbon-fixing reactions of the Calvin cycle and describe changes that occur in the
carbon skeletons of intermediates.
18. Describe the roles of ATP and NADPH in the Calvin cycle.
19. Describe what happens to rubisco (RubP carboxylase) when the O2 concentration is much higher
than CO2.
20. Explain the major consequences of photorespiration.
21. Describe two important photosynthetic adaptations that minimize photorespiration in some
plants.
22. Predict the fate of photosynthetic products.
23. Brainstorm techniques that could be used to determine photosynthetic rates.
24. Form, explain, and test hypotheses about how the rate of photosynthesis is related to light
intensity, wavelength of light, or other environmental variables.

BIOLOGY HIT SONGS OF THE WEEK
Photosynthesis (to the tune of The Muppet Song)
The plants are making glucose.
It’s happenin’ in the leaves!
And in the plants when sunlight hits
It’s photosynthesis!
They’re using six CO2.
Add in six H2O’s,
Chlorophyll in just the right dose –
Making a glucose!
It’s C6H12O6,
A simple sugar brew
With energy to use
Now transpirate the six O2.
The plants are making glucose.
It’s happenin’ in the leaves!
And in the plants when sunlight hits
It’s photosynthesis!
Photosynthesis (to the tune of Auld Lang Syne)
When sunlight bathes the chloroplast, and photons are absorbed
The energy's transduced so fast that food is quickly stored,
Photosynthetic greenery traps light the spectrum through
Then Calvin cycle machinery fixes the CO2.
Two chlorophylls (a, b to you) are cleverly deployed
In photosystems I and II, within the thylakoid
System I takes energy, at 700 (red)
While system II (with pigment b) takes 680 instead.
